Destruction of the motor or motor holding brake as a result of high voltage tolerances of the

motor holding brakes

If the voltage tolerances of the motor holding brakes are not complied with (24 V ± 10 %),

then the brake will malfunction, i.e. the brake will not reliably open. If the motor constantly

runs against the closed brake, the brake or the motor will be destroyed.

• Set the DC power supply to 26 V.

The following general conditions must be satisfied:

• Siemens three-phase motors must be used

• Siemens MOTION-CONNECT power cables must be used

• Motor cable lengths, max. 100 m

The total length of the power cables (motor feeder cables and DC link cables) must not

exceed the values listed in Chapter Combining line reactors and line filters (Page 136).

The motor brake must be connected via connector X11. It is not permitted to directly connect

the cable BR – to the electronics ground M.
