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 44.10 Brake
open torque.
Zero.
12.12 AI1 scaled value.
12.22 AI2 scaled value.
03.05 FB A reference 1.
03.06 FB A reference 2.
Parameter 44.02 Brake torque memory.
Parameter 44.10 Brake open torque.
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 44.09
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.
Minimum torque at brake release.
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.
