Description
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
torque.
See parameter 44.10 Brake open
Zero.

Parameter 44.02 Brake torque memory.
Parameter 44.10 Brake open
Source selection (see Terms and abbreviations
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
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.
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.
