-
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,
• This parameter cannot be changed while the drive is
running.

-
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.
0.00 s
0.00 … 60.00 s
Brake close delay.
100 = 1 s
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 (
), a
close command is given.
Note:
Check the compatibility of this setting with
(and the applicable deceleration time).
10.00 rpm
0.00 … 1000.00
rpm
Brake close speed.
See par.
Defines a brake close level delay. See parameter
.
0.00 s
0.00 … 10.00 s
Brake close level delay.
100 = 1 s
No.
