35.03 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
TORQ). 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...5 s
35.04 BRAKE CLOSE DLY
Defines the brake close delay. The delay counter starts when the motor actual speed has fallen below
the set level (parameter
Simultaneously with the counter start, the brake control function de-energises the relay output
controlling the brake and the brake starts closing. During the delay, the brake function keeps the motor
live preventing the motor speed from falling below zero.
Set the delay time to the same value as the mechanical make-up time of the brake (= operating delay
when closing) specified by the brake manufacturer.
0...60 s
35.05 BRAKE CLOSE SPD
Defines the brake close speed (an absolute value). See parameter
0...1000 rpm
35.06 BRAKE OPEN TORQ
Defines the motor starting torque at brake release (in percent of the motor nominal torque).
0...1000%
35.07 BRAKE CLOSE REQ
Selects the source for the brake close (open) request. 1 = Brake close request. 0 = Brake open
request.
Note: This parameter cannot be changed while the drive is running.
Bit pointer: Group, index and bit
35.08 BRAKE OPEN HOLD
Selects the source for the activation of the brake open command hold. 1 = Hold active. 0 = Normal
operation.
Note: This parameter cannot be changed while the drive is running.
Bit pointer: Group, index and bit
35.09 BRAKE FAULT FUNC
Defines how the drive reacts in case of mechanical brake control error. If brake control supervision
has not been activated by parameter
