242 Parameters
35.04 BRAKE OPEN
DELAY
Defines the brake open delay (= the delay between
the internal open brake command and the release of
the motor speed control). The delay counter starts
when the drive has magnetised the motor and risen
the motor torque to the level required at the brake
release (parameter 35.07 BRK OPEN TRQ).
Simultaneously with the counter start, the brake
function energises the relay output controlling the
brake and the brake starts opening.
Set the delay the same as the mechanical opening
delay of the brake specified by the brake
manufacturer.
0.10 s /
UINT32
0.00…5.00 s Brake open delay. 100 = 1 s / -
35.05 MODULATION
DELAY
Defines the duration of modulation starting from
reaching Brake close speed.
0.50 s /
UINT32
0.00…60.00 s Modulation delay. 100 = 1 s / -
35.06 BRAKE CLOSE
SPD
Defines the brake close speed (an absolute value).
See parameter 35.09 BRAKE CLOSE DLY.
3.0 rpm/
Real
0.0…1000.0 rpm Brake close speed. 10 = 1 rpm /

35.07 BRAKE OPEN
TORQ
Defines the brake open torque value. 0.0% / Real
-1000.0...
1000.0%
Constant brake open torque. - / 10 = 1%
35.08 BRAKE FAULT
FUNC
Defines how the drive reacts in case of a mechanical brake
control error. If brake control supervision has not been
activated by parameter 35.01 BRAKE CONTROL, this
parameter is disabled.
FAULT /
enum
FAULT The drive trips on fault BRAKE NOT CLOSED / BRAKE NOT
OPEN if the status of the optional external brake monitoring
signal does not meet the status presumed by the brake
control function. The drive trips on fault BRAKE START
TORQUE if the required motor starting torque at brake
release is not achieved.
0
ALARM The drive generates alarm BRAKE NOT CLOSED / BRAKE
NOT OPEN if the status of the optional external brake
monitoring signal does not meet the status presumed by the
brake control function. The drive generates alarm BRAKE
START TORQUE if the required motor starting torque at
brake release is not achieved.
1
OPEN FLT The drive generates fault BRAKE NOT CLOSED / BRAKE
NOT OPEN if the status of the optional external brake
monitoring signal does not match the status presumed by
the brake control function. The drive trips on fault BRAKE
START TORQUE if the required motor start torque at brake
release is not achieved.
