Function:
[Application Set the motor current for release
dependant] 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
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.
Function:
[0 - 30000 Set the motor speed for
RPM] activation of the mechanical
brake, when a stop condition is
present. The upper speed limit is
specified in 4-53 Warning Speed
High.

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 the
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 timeout when
brake feedback is activated.
