09 Function code

Refers to an open loop vector. Suitable for the usual high-performance control occasions, one inverter can only drive one motor. Such as machine tools, centrifuges, wire drawing machines, injection molding machines and other loads.

13

14

1: V/F control

15

16

It is suitable for occasions where the load requirement is not high or a VFD drags multiple motors, such as fans and pumps. It can be used for driving multiple motors with one VFD.

17

18

Tip: When selecting the vector control mode, the motor parameter identification process must be carried out. Only accurate motor parameters can give full play to the advantages of vector control.

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

89

90

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;

91

92

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

93

94

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.

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:

182

183

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.

184

185

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%.

186

187

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

188

189

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.

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.

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.

273

|Setting range|(% colspan="2" %)0.5kHz 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.

278

279

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.

280

281

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.

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.

336

337

Tens place: The carrier is associated with the output frequency

338

339

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.

340

341

Hundreds palce: Random PWM depth

342

343

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.

344

345

Thousands place: Over modulation option

346

347

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.

348

349

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.

350

351

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.

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.

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.

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.
