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:

Speed mode control commands:
FREQ (P)

Target speed The first acceleration time setting The first deceleration time setting
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.
4. Set M1025 = 1, the driver frequency command will now jump to the frequency designated
by FREQ, and acceleration/deceleration will be controlled on the basis of the acceleration
time and deceleration time specified by FREQ.
5. M1052 can be used to lock the current operating frequency.
6. M1044 can be used to temporarily pause operation, and the deceleration method will comply
with deceleration settings.
