For information on connecting the power, also refer to the diagrams relating to "System
integration". The rotor rotates counterclockwise if the torque motor is connected to phase
sequence U, V, W. See "Defining the direction of rotation (Page 35)"
Connection of circuit breaker
For the following configurations, you require a circuit breaker for each motor:
• Several motors are connected in parallel to one Motor Module.
• The current-carrying capacity of the feeder cable cross-section is less than the current
load capability of the Motor Module.
Connect all of the motors to be connected in parallel to a Motor Module via a circuit breaker.
• Connect phases U, V, W of the motor in question to the corresponding terminals of the
associated circuit breaker:
U - L1
V - L2
W - L3
• Connect phases U, V, W of the Motor Module to the circuit breaker terminals:
U - T1
V - T2
W - T3
• Connect the auxiliary NO contacts of the circuit breaker in series.
• Connect the auxiliary NO contacts to an input on the CU/NCU.
• Connect the auxiliary NO contact to an external drive fault of the drive using BICO
technology. This means that when a circuit breaker trips, the complete drive is shut down
(OFF2).
• You can also evaluate the auxiliary NO contact of the circuit breaker using the PLC.
• Adjust the circuit breaker to the rated current of the motor feeder cables +10 %.
