In vector control, the motor control algorithm supports five times weak magnetic operation, so
the set range of
E0-02
is 1 to 5 times of the motor rated frequency. When the rated frequency is
50Hz, please not set it higher than 250 Hz under vector control.
Under SVC vector control, the motor control algorithm supports 12r/min lowest speed (Min.
0r/min for VC control). The motor will stop when the speed command is less than the lowest
speed.
For V/F control,
E0-02
can be set as Max. 400.0Hz.
Note: When torque control mode selected in d2-00, the parameter setting is invalid.
