Select the input channel for the main given frequency of the inverter. There are 10 main given frequency channels:

0: Digital setting (no memory) (Potentiometer and terminal UP/DOWN adjustable, power failure no memory) The initial value is F0.08 value of Digital Setting Preset Frequency. The set frequency value of the inverter can be changed by ▲/▼ key of the keyboard (or the UP and DOWN of the multi-function input terminal). No memory means that after the inverter power off, the set frequency value is restored to the initial value;

1: Digital setting (memory) (Potentiometer and terminal UP/DOWN adjustable, power failure memory) The initial value is F0.08 "digital setting preset frequency" value. The set frequency value of the inverter can be changed by ▲/▼ key of the keyboard (or the UP and DOWN of the multi-function input terminal). Memory means that when the inverter is powered on again after power failure, the set frequency is the set frequency before the last power failure

2: AI1 3: AI2 refers to the frequency determined by the analog input terminal. The standard unit provides two analog input terminals (AI1, AI2), of which AI1 is 0V to 10V voltage input, AI2 can be 0V to 10V voltage input, or 4mA to 20mA current input.

4: Potentiometer set by keyboard potentiometer to set the frequency

When the frequency source is selected as a frequency stack (F0.07 is set to 1, 3, or 4), it is used to determine the adjustment range of the auxiliary frequency source. F0.05 is used to determine the object relative to the range, if it is relative to the maximum frequency (F0.10), the range is a fixed value; If it is relative to the primary frequency source X, its range will change as the primary frequency source X changes.

The secondary frequency source is used in the same way as the primary frequency source X when it is used as an independent frequency given channel (that is, the frequency source selected is switched from X to Y). When the secondary frequency source is used as a superposition given (i.e., the frequency source selected is X+Y, X to X+Y switching, or Y to X+Y switching), there are the following special features:

When the auxiliary frequency source for digital or pulse potentiometer timing, preset frequency (F0.08) does not work, through the keyboard ▲/▼ key (or multi-function input terminal UP, DOWN) can be adjusted on the basis of the main given frequency.

When the auxiliary frequency source is given as an analog input (AI1, AI2) or a pulse input, 100% of the input setting corresponds to the auxiliary frequency source range (see F0.05 and F0.06 instructions). If you need to adjust up or down from the main given frequency, set the analog input to a range of n% to +n%.

The frequency source is timed for pulse input, similar to analog quantity setting.

Tip: The secondary frequency source Y and the primary frequency source X Settings cannot be the same, that is, the primary and secondary frequency sources cannot use the same frequency given channel.

0: The same direction

1: The direction is reversed

2: Reverse prohibition

By changing the function code, the steering of the motor can be changed without changing any other parameters, which is equivalent to the conversion of the rotation direction of the motor by adjusting any two lines of the motor (U, V, W).

Tip: The motor running direction will be restored to the original state after parameter initialization. For the system debugging is strictly prohibited to change the motor steering occasions with caution.

For example, in torque control, speed control is not effective. In order to avoid the "speed" of material breakage, the upper limit frequency can be set with the analog quantity. When the inverter runs to the upper limit frequency value, the torque control is invalid and the inverter continues to run at the upper limit frequency.

F0.12Upper limit frequencyFactory default50.00Hz
Setting rangeLower frequency F0.14 to Maximum frequency F0.10
F0.13Upper frequency biasFactory default0.00Hz
Setting range0.00Hz to Maximum frequency F0.10

When the upper limit frequency is given by the analog quantity, this parameter is used as the bias quantity calculated by the upper limit frequency, and this upper limit frequency offset is added to the set value of the upper limit frequency of the simulation as the set value of the final upper limit frequency.

F0.14Lower frequencyFactory default0.00Hz
Setting range0.00Hz to Upper limit frequency F0.12

When the VFD starts to run, it starts from the start frequency. If the given frequency is less than the lower limit frequency during operation, the VFD runs at the lower limit frequency, stops or runs at zero speed. You can set which mode of operation to use with F0.15.

F0.15Lower frequency Operating modeFactory default0
Setting range

0: Run at the lower limit frequency

1: Stop

2: Zero speed operation

Select the operating state of the inverter when the set frequency is lower than the lower limit frequency. In order to avoid the motor running at low speed for a long time, you can use this function to choose to stop.

F0.16Carrier frequencyFactory defaultModel determination
Setting range0.5kHz to 16.0kHz

This function regulates the carrier frequency of the inverter. By adjusting the carrier frequency, the motor noise can be reduced, the resonance point of the mechanical system can be avoided, and the interference of the line to the floor drain current and the VFD can be reduced.

When the carrier frequency is low, the higher harmonic component of the output current increases, the motor loss increases, and the motor temperature rise increases.

When the carrier frequency is high, the motor loss decreases and the motor temperature rise decreases, but the VFD loss increases, the VFD temperature rise increases and the interference increases.

F0.18Acceleration time 1Factory defaultModel determination
Setting range0.0s to 6500.0s
F0.19Deceleration time1Factory defaultModel determination
Setting range0.0s to 6500.0s

One place: Select PWM mode

VFD can choose 5-section wave or 7-section wave, the 5-section wave converter has little heat, and the 7-section wave motor has little noise. When the bit is 0, 7 waves are generated at low frequency and 5 waves are generated at high frequency. At 1 o 'clock, the whole wave is 7 stages, and at 2 o'clock, the whole wave is 5 stages.

Tens place: The carrier is associated with the output frequency

When the output frequency is low, reducing the PWM carrier can increase the low frequency starting torque and reduce the electromagnetic interference during starting. When the bit is 1, the program automatically reduces the PWM carrier when the output frequency is low.

Hundreds place: Random PWM depth

In order to make the motor noise spectrum flatter, you can turn on the random PWM function, after the function is turned on, the PWM carrier is no longer a fixed value, but fluctuates around the F0.16 set carrier. When the bit is not 0, the random PWM function works. The larger the value, the wider the fluctuation range and the flatter the noise spectrum. It should be noted that after opening the random carrier, the electromagnetic noise of the motor will not necessarily be reduced, and the actual noise perception varies from person to person.

Thousands place: Over modulation option

The over modulation function can increase the maximum output voltage of the inverter, but it also makes the current distortion more obvious. When the bit is 1, the over modulation function is enabled.

Acceleration time refers to the time required for the inverter to accelerate from zero frequency to the reference frequency of acceleration and deceleration (determined by F0.24), as shown in t1 in Figure 9-0-1.

Deceleration time refers to the time required for the VFD to decelerate from the reference frequency of acceleration and deceleration (determined by F0.24) to the zero frequency, see t2 in Figure 9-0-1.

2: 0.01s

This function is used to determine all acceleration and deceleration time units.

Note that when the value is modified, the actual acceleration and deceleration time will also change accordingly (the decimal point position changes, the actual display number remains unchanged), Therefore, it is necessary to adjust the various acceleration and deceleration Settings according to the situation.

Note the following function codes: F0.18, F0.19, F8.01, F8.02, F8.03, F8.04, F8.05, F8.06, F8.07, F8.08.

F1 group start stop control

F1.00Start-up operation modeFactory default00
Setting range

LED ones place: Boot mode

0: Start directly from the start frequency

1: Start after speed tracking and direction judgment

2: The asynchronous machine starts with pre-excitation

0: Direct startup

1: Start after speed tracking and direction judgment

The inverter first detects the steering and speed of the motor, and then starts according to the real-time speed. It is suitable for instantaneous power failure and restart of large inertia load or smooth restart of rotating equipment. Set accurate F2 motor parameters for better speed tracking and restart performance.

2: The asynchronous machine starts with pre-excitation

Pre-excitation current, time and DC braking current, time share function code. If F1.09 pre-start braking time is set to 0, start from the start frequency. When the value is not set to 0, pre-excitation is implemented before startup to improve the dynamic response speed.

F1.01Speed tracking modeFactory default0
Setting range

LED tens place: speed tracking direction

0: One to the stop direction

1: One to the starting direction

2: Automatic search

This parameter determines the direction from which to start speed tracking. Please set it correctly according to the actual situation. If the setting is wrong, the startup may fail. In the case of not knowing the starting direction, you can set to automatic search, the program will automatically judge the starting direction, but the search time will be lengthened accordingly.

F1.02Speed tracking timeFactory default1.00s
Setting range0.01 to 60.00s

If the speed tracking time is too short, the tracking may end without tracking the actual frequency. At F1.01=002X, if the search direction is wrong, two searches will be performed and the actual search time will be doubled.

F1.06Starting frequencyFactory default0.00Hz
Setting range0.0s to 60.00Hz
F1.07Startup frequency durationFactory default0.0s
Setting range0.0 to 50.0s

In order to ensure the torque during startup, please use the appropriate startup frequency. In addition, the magnetic flux is established when waiting for the motor to start, so that the starting frequency is maintained for a certain time before accelerating. The starting frequency is maintained for a certain time before accelerating. The startup frequency F1.06 is not limited by the lower frequency. If the frequency given less than startup frequency, the AC driver can no be started, and it will standby state. The startup frequency holding time is not work during forward/reverse switching. The holding time is not included in the acceleration time, but is included in the running time of the simple PLC.

F1.08Braking current before startingFactory default80.0%
Setting range0.0 to 150.0%
F1.09Braking time before startingFactory default0.0s
Setting range0.0 to 60.0s

Starting DC braking is generally used to stop the motor completely before starting.

If the starting mode is starting after the DC braking, the AC driver will execute the DC braking as the setting value, and it will start running after the setting starting braking time value. It will direct start without DC braking if the setting DC braking time is 0. The braking power is greater with the greater DC braking current.

F1.10Shutdown modeFactory default0
Setting range

0: Slow down stop

1: Free stop

0: Slow down stop

After the stop command is effective, the inverter reduces the output frequency according to the deceleration mode and the defined acceleration and deceleration time, and stops after the frequency drops to 0.

1: Free stop

When the stop command is valid, the inverter terminates output immediately. The load stops freely according to mechanical inertia.

F1.11Stop DC braking start frequencyFactory default0.00Hz
Setting range0.00Hz to Maximum frequency F0.10
F1.12Stop DC braking wait timeFactory default0.0s

F1.13Stop DC braking currentFactory default80.0%
Setting range0% to 150%
F1.14Stop DC braking durationFactory default0.0s
Setting range0.0s to 100.0s

DC braking start frequency: slow down the stopping process. When the output frequency is less than this frequency, the DC braking process starts to stop.

DC braking waiting time: When the output frequency is reduced to F1.11 DC braking starting frequency, the inverter stops output and starts timing. After the delay time set by F1.12, DC braking starts again. Used to prevent over current failure caused by DC braking at high speeds.

Stop DC braking current: refers to the amount of DC braking applied. The greater the value, the stronger the DC braking effect.

DC braking time: the time added to the DC braking amount. When this value is 0, it means that there is no DC braking process, and the inverter stops according to the set deceleration stop process.

F1.18Magnetic flux braking operating voltageFactory defaultModel-based setting
Setting range110% to 150%
F1.19Flux brake limitingFactory default20%
Setting range0 to 200%

When the motor decelerates the feedback energy, opening the flux brake can consume the feedback energy on the motor, so as to achieve rapid deceleration of the motor. This function is only effective in asynchronous motor VF control, and turning on this function will correspondingly increase motor loss and motor temperature rise.

Magnetic flux braking gain: The strength of magnetic flux braking, the greater the parameter, the greater the magnetic flux braking current.

Magnetic flux braking action voltage: When the relative value of the bus voltage is higher than this value, magnetic flux braking begins to work.

Flux brake limiting: The upper limit of the flux brake voltage, which may cause the output current of the inverter to be too high.

1: S-curve, S-type acceleration and deceleration curve is mainly provided for the load that needs to slow down noise and vibration during acceleration and deceleration, reduce start-stop impact, or decrease torque at low frequency, and short-time acceleration at high frequency. If an over current or over load failure occurs at startup, reduce the set value of [F1.21].

F1.21S-curve initial acceleration rateFactory default50.0%
Setting range20.0% to 100.0%
F1.22S-curve initial deceleration rateFactory default50.0%
Setting range20.0% to 100.0%

S-curve Initial acceleration rate: The rate at which the acceleration process begins to increase in frequency. The smaller the initial acceleration rate, the more curved the S-curve of the acceleration process, whereas the larger the initial acceleration rate, the closer the acceleration S-curve to a straight line. To make the acceleration curve softer, you can reduce the initial acceleration rate and extend the acceleration time.

F1.23Zero speed holding torqueFactory default0
Setting range0.0% to 150.0%

Set the output torque of the inverter at zero speed. If the torque setting is large or the duration is long, attention should be paid to the heat dissipation of the motor.

F1.24Zero speed holding torque timeFactory defaultModel setting
Setting range

0.0 to 6000.0s

If the value is set to 6000.0s, the value remains unchanged without time limitation

Set the torque holding time when the inverter is running at zero speed. The timing starts when the operating frequency is 0Hz, and the inverter stops output after the time reaches the set zero-speed holding torque time. Among them, the effective timing value is 0 to 5999.9s, and the parameters are set in the effective timing value of the VFD at the set time. After the time is full, the VFD terminates and maintains the zero-speed torque.

If the parameter setting is equal to 6000.0s, the VFD is not timed and defaults to long-term validity, and the zero-speed torque holding is terminated only after the stop command is given or the non-zero operating frequency is given.

Setting an appropriate zero-speed holding torque time can effectively achieve energy saving and protect the motor.

F1.25Start pre-excitation timeFactory default0.20
Setting range0.00 to 60.00s

This parameter is only valid if F0.00=0, in the open loop vector start, appropriate pre-excitation can make the start smoother.

During the waiting time of power failure and restart, the inverter does not accept the running command, but if the stop command is entered during this period, the inverter will release the restart state.

F1.28Power failure restart waiting timeFactory default0.50s
Setting range0.00 to 120.00s

The speed dynamic response characteristic of vector control can be adjusted by setting the proportional coefficient and integration time of the speed regulator. Proportional increase

If the integration time is reduced, the dynamic response of the speed loop can be accelerated. The system may oscillate if the proportional gain is too large or the integration time is too small.

Recommended adjustment method:

If the Factory parameters cannot meet the requirements, fine-tune the Factory default parameters: first increase the proportional gain to ensure that the system does not oscillate; Then the integration time is reduced so that the system has both faster response characteristics and smaller overshoot.

Note: Setting the PI parameter incorrectly may result in excessive speed overshoot. Even overvoltage failure occurs when overshoot falls back.
