2.5 Holding
brake
Optional. Holds the servo axis when no power is being supplied to the
machine.
The holding brake works with the "electrically-released" principle. At zero
current, a magnetic force acts on the brake armature disc. This means
that the brake is locked and holding off the axis.
With the application of 24 V DC, the electrical field cancels the permanent
magnetic field and the brake opens.
The drive controller regulates the holding brake. This ensures the correct
on and off sequence in all operating states.
DANGER
Falling axes!
Danger to personnel. Body parts could be pinched or se-
vered.
⇒
The holding brake itself does not guarantee personnel
safety. Personnel safety must be secured by other
measures such as protective bars or an additional
brake in the machine.
CAUTION
Premature wear of the holding brake is possible!
The holding brake wears down after approximately
20,000 motor revolutions in a closed state.
⇒
Do not use the holding brake to stop a moving axis.
This is only permitted in an emergency stop (E-stop)
situation!
Note:
If motors are stored for extended periods, then the transferrab-
le torque of the holding brakes must be checked before the
motor can be used. If the torque specified in the data sheets is
not achieved, then it becomes necessary to refinish the hol-
ding brake prior to use.
⇒
Note the guidelines in section 11.5, Refinishing the holding brake, pa-
ge 11-8.
