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. 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 regenerat ive 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 P1 and P. (Factory-wired.)

8. Stepdown transformer is required for coil voltage of magnetic contactor more than 200V class servo am plifiers.
