Releasing the motor holding brake when mounting the motor
The motor holding brake can be released via the X4 interface. This means that the shaft of the
S120M can be moved without connecting the supply voltage via the hybrid cable.
X4 is a commissioning interface. Interface X4 must not be used in normal operation. Cover the
X4 interface with the protective cap supplied.
