2-20 Release Brake Current
Range: Function:
Application
dependent*
[Application dependant] 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
.
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.
2-21 Activate Brake Speed [RPM]
Range: Function:
Application
dependent*
[0 - 30000 RPM] 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
Warning Speed High
.
2-22 Activate Brake Speed [Hz]
Range: Function:
Application
dependent*
[Application dependant] Set the motor frequency for activation of the mechanical brake, when a stop condition is present.
2-23 Activate Brake Delay
Range: Function:
0.0 s* [0.0 - 5.0 s] 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
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 pa-
rameter is a part of the stopping function.
