Note: 1. The Servopack SVON signal and the power regenerative converter signal, MANUAL RUN or AUTO RUN, should be turned off
at the same time when the emergency stop SW (ESP) is turned off.
2. Wire the VS-656RC5 and the SGDB so that the RY relay and the main circuit power supply turn off when an alarm occurs in the
Servopack or the power regenerative converter.
* 1 The DC bus wiring ( ¨1 − ¨, © − © ) between the Servo unit and the power regenerative unit should be 5m or less.
* 2 Connect the Servo unit’s AC power supply terminals R/L1, S/L2, and T/L3 to the secondary side of the power coordinating reac-
tor.
* 3 Connect terminals r/
1, / 2 on the Servo unit and terminals r1/ 11, 1/ 21, and t1/ 31 on the VS-656RC5 to the primary side of
the power coordinating reactor.
