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

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.

Function:
brake, when a stop condition is
present.
Function:
[0.0 - 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.
Function:
[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.
Function:
[0.00 - 5.00 This value defines the time it takes for
s] the mechanical brake to open. This
parameter must act as a time-out when
brake feedback is activated.
