NOTICE
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
Note
The motor brake must be connected via connector X11. It is not permitted to directly connect
the cable BR – to the electronics ground M.
Note
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 filter times to debounce terminals X21.3 and X21.4 can be parameterized (see
SINAMICS S120/S150 List Manual). Additional parameter settings are also required in order
to prevent discrepancy errors when performing bit pattern tests (light/dark tests). For
comprehensive information, see the SINAMICS S120 Safety Integrated Function Manual,
Section "Controlling the safety functions".
