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 sensor, configure a sequence that will shut off main circuit power when the thermal sensor
operates.
3. For the servo amplifier, configure a sequence that will switch the servo on after the FR-CV-H is ready.
4. For the FR-CV-H, the RSO signal turns off when it is put in a ready-to-operate status where the reset signal is input.
Configure a sequence that will make the servo inoperative when the RSO signal is on.
5. Configure a sequence that will make a stop with the emergency stop input of the servo system controller if an alarm occurs
in the FR-CV-H. When the servo system controller does not have an emergency stop input, use the forced stop input of the
servo amplifier to make a stop as shown in the diagram.
6. 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.
7. When using the servo amplifier of 11k to 22kW, make sure to connect P
8. Stepdown transformer is required for coil voltage of magnetic contactor more than 200V class servo amplifiers.
