282 Parameters
44.16
Brake reopen delay
Defines a minimum time between brake closure and a
subsequent open command.
0.00 s
0.00 … 10.00 s
Brake reopen delay.
100 = 1 s
44.17
Brake fault function
Determines how the drive reacts upon a mechanical brake
control error.
Note:
If parameter
44.07
Brake acknowledge selection
is
set to
No acknowledge
, acknowledgment status
supervision is disabled altogether and will generate no
warnings or faults. However, the brake open conditions
are always supervised.
Fault
Fault
The drive trips on a
71A2
Mechanical brake closing failed
The drive trips on a
A7A5
Mechanical brake opening not
allowed
fault if the brake open conditions cannot be
fulfilled (for example, the required motor starting torque is
not achieved).
0
Warning
The drive generates a
A7A1
Mechanical brake closing
failed
The drive generates a
A7A5
Mechanical brake opening
not allowed
warning if the brake open conditions cannot
be fulfilled (for example, the required motor starting torque
is not achieved).
1
Open fault
Upon closing the brake, the drive generates a
A7A1
Mechanical brake closing failed
warning if the status of the
acknowledgment does not match the status presumed by
the brake control logic.
The drive trips on a
71A5
Mechanical brake opening not
allowed
fault if the brake open conditions cannot be
fulfilled (for example, the required motor starting torque is
not achieved).
2
44.18
Brake fault delay
Defines a close fault delay, ie. time between brake closure
and brake close fault trip.
0.00 s
0.00 … 60.00 s
Brake close fault delay.
100 = 1 s
44.202 Torque proving
Selects whether Torque proving (electrical test) is active or
not. For more information on the function, see section
Brake system checks – Torque proving
on page
536
.
Note
: For scalar motor control, disable Torque proving
and Brake open torque. Select the following:
44.09
Brake open torque source
=
Zero
44.10
Brake open torque
= 0%
44.202
Torque proving
=
Not selected
Not selected
Not selected
Torque proving is inactive.
0
Selected
Torque proving is active.
