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
