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
NB!
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.
Function:
Set the motor speed for activation of the mechanical brake, when a stop condition is present. The
upper speed limit is specified in par. 4-53
Function:
Set the motor frequency for activation of the mechanical brake, when a stop condition is present.
Function:
Enter the brake delay time of the coast after 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
Function:
Set the time interval from the moment when the motor is stopped until the brake closes. This pa-
rameter is a part of the stopping function.
