Description
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.

Source selection (see Terms and abbreviations
Selects the source of an external brake close request signal.
When on, the signal overrides the internal logic and closes
the brake.
0 = Normal operation/No external close signal connected
1 = Close brake
Notes:
• In an open-loop (encoderless) application, if the brake is
kept closed by a brake close request against a modulating
drive for longer than 5 seconds, the brake is forced to
close and the drive trips on a fault,
opening not allowed.
• This parameter cannot be changed while the drive is
running.
