Parameters 251
44.12 Brake close request 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 (encoderless) 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, 71A5
Mechanical brake opening not allowed
• This parameter cannot be changed while the drive is
running.

44.13 Brake close delay Specifies 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.
0.00 s
0.00…60.00 s Brake close delay. 100 = 1 s
44.14 Brake close level Defines the brake close speed as an absolute value.
After motor speed has decelerated to this level, a close
command is given.
10.0 rpm
0.0…1000.0 rpm Brake close speed. See par.
46.01
44.15 Brake close level
delay
Defines a brake close level delay. See parameter 44.14
Brake close level.
0.00 s
0.00 … 10.00 s Brake close level delay. 100 = 1 s
