Description
Selects the source of an external brake close request signal.
When on, the signal overrides the internal logic and closes
the brake.
0 = Normal operation/No external close signal connected
1 = Close brake
Notes:
• In an open-loop (encoder-less) application, if the brake is
kept closed by a brake close request against a
modulating drive for longer than 5 seconds, the brake is
forced to close and the drive trips on a fault,

Source selection (see Terms and abbreviations
152).
Defines a delay between a close command (that is, when
the brake control output is de-energized) and when the drive
stops modulating. This is to keep the motor live and under
control until the brake actually closes.
Set this parameter equal to the value specified by the brake
manufacturer as the mechanical make-up time of the brake.
Brake close delay.
Defines the brake close speed as an absolute value.
After motor speed remains below this level for the duration
of the brake close level delay
delay), a close command is given.
Note: Check the compatibility of this setting with
mode (and the applicable deceleration time).
Brake close speed.
Defines a brake close level delay. See parameter
Brake close level.
Brake close level delay.
Defines a minimum time between brake closure and a
subsequent open command.
