Mounting and Installation
Check if the holding brake is functioning properly before mounting the
motor. How to check the holding brake is described below as well as
procedures to follow if any refinishing of such could be necessary.
Premature wear of the holding brake is possible!
The holding brake wears down after appropx. 20000
motor revolutions when closed.
⇒ Please therefore note the following instructions!
CAUTION
Prerequisite: The motor is equipped with a holding brake and has been
stored for an extended period.
⇒ Check the transferrable holding torque of the holding brake.
If the holding torque listed in the dimensional data sheets is not achie-
ved, then refinish the holding brake.
The following preconditions must be set before the holding brake can be
refinished.
Prerequisite: No electrical connection of motor and drive controller.
⇒ Electrical connection between motor and drive controller must be se-
parated.
⇒ Turn motor manually with holding brake closed approximately 50 ti-
mes.
The holding brake is now refinished and ready to operate.
