10 0: Speed sensorless vector control
11
12 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.

81 Select the input channel for the main given frequency of the inverter. There are 10 main given frequency channels:
82
83 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;
84
85 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
86
87 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.
88
89 4: Potentiometer set by keyboard potentiometer to set the frequency
90
91 5: PULSE pulse setting (DI4) The frequency setting is set by the terminal pulse. Pulse given signal specifications: voltage range, frequency range 0kHz to 20kHz. Note: Pulse Settings can only be input from the multi-function input terminal DI4.
92
93 6: Multi-speed Select the multi-speed operation mode. The F5 "input terminal" and FD "multi-speed and PLC" parameters need to be set to determine the correspondence between a given signal and a given frequency.
94
95 7: Simple PLC Select simple PLC mode. When the frequency source is a simple PLC, the FD group "multi-speed and PLC" parameters need to be set to determine the given frequency.
96
97 8: PID selection process PID control. In this case, set the PID function of the F9 group. The operating frequency of the inverter is the frequency value after PID action. For the meaning of PID set source, feed quantity and feedback source, please refer to the introduction of F9 group "PID Function".
98
99 9: Communication set means that the main frequency source is given by the host computer through communication.

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.

168 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:
169
170 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.
171
172 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%.
173
174 The frequency source is timed for pulse input, similar to analog quantity setting.
175
176 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.

192 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).

232 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.

239 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.

244 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.

260 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.
261
262 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.
263
264 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.

314
315 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.
316
317 Tens place: The carrier is associated with the output frequency
318
319 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.
320
321 Hundreds place: Random PWM depth
322
323 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.
324
325 Thousands place: Over modulation option
326
327 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.
328
329 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.
330
331 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.

845 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
846
847 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.
848
849 Recommended adjustment method:
850
851 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.
