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".

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.

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.

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.

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 palce: 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.

736 Tip: Before tuning, you must set the correct motor type and rating parameters (F2.00 to F2.05).
737
738 0: No operation is performed, that is, tuning is disabled.
739
740 1: Static tuning 1, suitable for the motor and the load is not easy to come off and can not be rotated tuning occasions, static tuning learning asynchronous motor F2.05-F2.10 or synchronous motor F2.22 to F2.25 parameters, wherein synchronous motor back potential is calculated according to F2.01 and F2.03, if the motor power or current and the actual difference is large, Calculations may not be accurate.
741
742 Action description: Set the function code to 1, and press the RUN key to confirm, the inverter will perform static tuning.
743
744 2: Complete tuning, in order to ensure the dynamic control performance of the inverter, please select rotary tuning, rotary tuning motor must be disconnected from the load (no-load). After selecting rotary tuning, the inverter first performs static tuning, and after static tuning, the motor accelerates to 80% of the rated frequency of the motor, and maintains it for a period of time, and then decelerates and stops, and the rotary tuning ends.
745
746 Action description: Set the function code to 2, and press the RUN key to confirm, the inverter will perform rotation tuning.
747
748 3: Static tuning 2, different from static tuning 1, the tuning needs to manually input the asynchronous motor no-load current F2.10, the program will calculate the mutual inductance F2.09 according to the current, the other is the same as static tuning 1.
749
750 Action description: Set the function code to 3, and press the RUN key to confirm, the inverter will perform static tuning.
751
752 Note: Tuning can only be effective in keyboard control mode, acceleration and deceleration time is recommended to use the factory default.
