Over current stall preventive mode (Settable range 10~200%)
This function is to prevent when motor current exceeds stall current from stall.
There are 2 kinds of acceleration time slopes when motor acceleration current
exceeding stall current occurs:
Instantaneous load increase during steady operation and current exceeding over
current stall, revolution frequency will drop till current dropped to within stall current
level.

Cd57
Maximum frequency setting FH (Settable range 10~240)
This function cannot be modified during revolution.
When Cd05=11, the maximum frequency V/F slope FH
Settable range 10Hz-240Hz
Please refer to function code table Cd60.
§
Cd58
Base frequency setting Fb (Settable range 10~240)
This function cannot be modified during revolution.
When Cd05=11, the base frequency V/F slope Fb
Settable range 10Hz-240Hz (Fb
≦
FH). Please refer to function code table Cd60.
