Holding brake control
This basic function is used for low-wear control of a holding brake.
Intended use
Motor holding brakes are used to lock axes if the controller is inhibited or in case of "mains
off" system status. This is not only important for vertical axes but also for e.g. horizontal
axes which may cause various problems if the motion is not controlled.
Examples:
Loss of the reference information after mains OFF and further spinning of the drive.
Collision with other moving machine parts.
Danger!
Please note that the holding brake is an important element of the safety concept
of the entire machine.
Thus, proceed very carefully when commissioning this system part!
Stop!
Holding brakes on Lenze motors are not intended for braking during operation.
The increased wear caused by braking during operation can destroy the motor
holding brake!
Note!
•
Deactivate automatic DC-injection braking when a holding brake is used!
– For this purpose, go to
C00019
and set the
Auto DCB
threshold to "0".
– Background: Controller inhibit is already activated by the holding brake
control.
• If an electrically holding (self-releasing) brake is to be controlled instead of an
electrically released (self-holding) brake, the trigger signal must be inverted!
