330 Parameters
Defines the brake open delay, ie. the delay between the
internal open brake command and the release of motor speed
control. The delay timer starts when the drive has magnetized
the motor and increased the motor torque to the level required
for brake release (parameter
). Simultaneously with the timer start, the brake
control logic energizes the brake control output and the brake
starts to open.
Set this parameter to the value of mechanical opening delay
specified by the brake manufacturer.
0.00 s
0.00 … 5.00 s
Brake open delay.
100 = 1 s
Defines a source that is used as a brake opening torque
reference if
• its absolute value is greater than the setting of parameter
, and
• its sign is the same as the setting of

). -
Defines the sign (ie. direction of rotation) and minimum
absolute value of the brake open torque (motor torque
requested at brake release in percent of motor nominal
torque).
The value of the source selected by parameter
is used as the brake open torque only if it
has the same sign as this parameter and has a greater
absolute value.
Note:
This parameter is not effective in scalar motor control
mode.
0.0%
-1600.0 … 1600.0% Minimum torque at brake release.
See par.
Selects a source that prevents the brake from opening.
0 = Normal brake operation
1 = Keep brake closed
Note:
This parameter cannot be changed while the drive is
running.
