10.1.2 Connection to MP920 Servo Module SVA-01A
∗
represents twisted-pair wires.
Note 1. Connection cables (model: JEPMC-W6050-
) to connect the multi-winding drive unit to the MP920 are pre-
pared by Yaskawa. For details, refer to
Machine Controller MP920 User’s Manual design and maintenance
(No.:
SIEZ-C887-2.1).
2. Only the signals that are related to the multi-winding drive unit and MP920-series SVA-01A are given in this
example.
3. Incorrect signal connections may damage the machine controller, multi-winding drive unit, SERVOPACKs, and
converters.
4. Open the signal lines not to be used.
5. The above connection diagram shows the connections for only one axis. When using other axes, make connec-
tions to the SERVOPACK in the same way.
6. Short-circuit the normally closed (NC) input terminals that are not used at the I/O connector section of the
machine controller.
7. Make the settings so that the servomotor can be turned ON/OFF by the Servo ON signal (/S-ON).
8. The SERVOPACK incorporates safety functions to protect people from the hazardous operation of the movable
parts of the machines, reduce the risk, and ensure the safety of the machine in operation. Necessary circuits and
settings are required in CN8 to use these functions. If these functions are not used, use the SERVOPACK with the
enclosed safety jumper connected to CN8. For details, refer to
5.11 Safety Function.
