App. 4.4 Electrical Installation and configuration diagram
WARNING
Turn off the molded-case circuit breaker (MCCB) to avoid electrical shocks or
damages to the product before starting the installation or wiring.
CAUTION
The installation complies with IEC/EN 60204-1. The voltage supply to machines
must be 20 ms or more of tolerance against instantaneous power failure as
specified in IEC/EN 60204-1.
Connecting a servo motor for different axis to U, V, W, or CN2_ of the servo
amplifier may cause a malfunction.
Securely connect the cables in the specified method and tighten them with the
specified torque. Otherwise, the servo motor may operate unexpectedly.
The following shows representative configuration examples to conform to the IEC/EN/UL/CSA standards.
