8.3.2.2 Holding brake
On request the motors can be equipped with a holding brake. The brake is
mounted in the motor housing on the B-side. The mechanical dimensions of the
motor are changed. See the dimensions table. The power supply infeed is through
the motor cable. Please see to the poling being correct.
