4.3.11. Turning the motor holding brake on and off
Compax3 controls the holding brake of the motor and the power output stage. The
time behavior can be set.
Application:
For an axis to which torque is applied in the stationary state (e.g. for a z-axis) the
drive can be switched on and off in a manner such that no load movement takes
place. The drive thereby remains energized during the holding brake response
time. This is adjustable.
The power output stage current is de-energized by:
Error or
the control word
the ServoManager
Thereafter the motor is braked to zero rotation speed on the set ramp.
When zero speed is reached, the motor is de-energized with the delay "brake clo-
sing delay time".
