DZB100 Series
Parameter Settings
F1-
27
Parameter Name Over-current stall prevention during steady-state operation
Factory Setting 170%
Unit 1%
Settings 50 200%
During steady-state operation with the motor load rapidly increasing, the AC drive output
current may exceed the limit specified in F1-27. When this occurs, the output frequency will
decrease to maintain a constant motor speed. The drive will accelerate to the steady-state
operating frequency only when the output current drops below the level specified by F1-27.
A setting of 100% is equal to the rated current of the drive.

Parameter Name DC braking voltage
Factory Setting 0
Unit 1V
Settings 0 50V
This parameter determines the DC voltage that will be applied to the motor during braking
when the Motor Stop Method is set to "RAMP stop" (refer to F1-02).
Note: When setting this parameter, begin at a lower voltage level then increase the value until
sufficient holding torque is achieved. The rated motor current cannot be exceeded.
