16-9 Explanation of various PLC speed mode controls

Speed mode supports SVC control. Under the speed mode of SVC control, it cannot be
performed successfully unless finish motor parameter auto tuning ahead of time.
Control methods and settings are explained as follows:

FREQ (P)
Target speed
Example of speed mode control:
Before performing speed control, if the SVC control method is used, setting of electromechanical
parameters must first be completed.
1. Setting D1060 = 0 will shift the converter to the speed mode (default).
2. Use the FREQ command to control frequency, acceleration time, and deceleration time.
3. Set M1040 = 1, the driver will now be excited, but the frequency will be 0.
