Figure 5-32 Brake sequence
This parameter should be set to a level that is required to hold a load when the brake is released.
When stopping, the drive reference can be removed (i.e. Pr 1.11 = 0), but the brake will remain energized (open), until the motor has remained at a
speed below the brake apply speed for the delay defined by Pr 12.46. The delay prevents rapid activation and de-activation of the brake when fine
control of a motor is required close to zero speed.
See Pr 12.45 for more information.
