Default value: Size related
Parameter type: Range, 10 - par. 16-37 A
Setup: All setups
Conversion index: -2
Data type: Uint32
Change during operation: True
Set the motor current for release of the mechanical braking when a start condition is present. The default value is the maximum
current the inverter can provide for the particular power size. The upper limit is specified in parameter 16-37 Inv. Max. Current.
N O T I C E
When mechanical brake control output is selected, but no mechanical braking is connected, the function does not work by de-
fault setting due to too low motor current.
