Tab. 6:
Electrical data – motor connections on motor series 32xx BX4 SC
Motors in the version with SCDC have a 2-wire cable. In this operating mode, the servomo-
tor is connected in the same way as a conventional DC motor. The rotation direction of the
motor is determined by the polarity of the connection wires.
