524 Overspeed Limit
Overspeed Limit
Sets the incremental amount of the output frequency (above maximum speed: either
P520 [Max Fwd Speed] or P521 [Max Rev Speed]) allowable for functions such as slip
compensation. Units:
Default:
Min/Max:

525 Zero Speed Limit
Zero Speed Limit
Establishes a band around zero speed that is used to determine when the drive considers
the motor to be at zero speed. Units:
Default:
Min/Max:
