FC 300 Programming Guide
Function:
Set the motor current for release of the
mechanical brake, 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 par. 16-37 Inv.
Max. Current.
NOTE
When Mechanical brake control
output is selected but no
mechanical brake is connected,
the function will not work by
default setting due to too low
motor current.

2-23 Activate Brake Delay
Range: Function:
0.0 s [0.0 - 5.0 Enter the brake delay time of the coast after
*
s] ramp-down time. The shaft is held at zero speed
with full holding torque. Ensure that the
mechanical brake has locked the load before the
motor enters coast mode. See Mechanical Brake
Control section in the Design Guide.
2-24 Stop Delay
Range: Function:
0.0 s [0.0 - 5.0 s] Set the time interval from the moment when
*
the motor is stopped until the brake closes.
This parameter is a part of the stopping
function.
