0.00 s / real32Defines 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 44.3 Brake open torque reference).
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.

Brake open torque /
uint32
Defines a source that is used as a brake opening torque
reference if
• its absolute value is greater than the setting of
parameter 44.10 Brake open torque, and
• its sign is the same as the setting of 44.10 Brake
open torque.
See parameter 44.10 Brake open torque.

0.0 % / real32Defines 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 44.9
Brake open torque source 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.

Not selected / uint32Selects 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.
