Note 1. Configure a sequence that will shut off main circuit power at an emergency stop or at FR-CV-H or servo amplifier alarm
occurrence.
2. For the servo motor with thermal relay, configure a sequence that will shut off main circuit power when the thermal relay
operates.
3. For the servo amplifier, configure a sequence that will switch the servo on after the FR-CV-H is ready.
4. When using the servo amplifier of 7kW or less, make sure to disconnect the wiring of built-in regenerative resistor (2kW or less:
P-D, 3.5k to 7kW: P-C.
5. When using the servo amplifier of 11k to 22kW, make sure to connect P
1
and P. (Factory-wired.)
6. Stepdown transformer is required for coil voltage of magnetic contactor more than 200V class servo amplifiers.
