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 regenerative resistor (2kW or
less: P
and D, 3.5k to 7kW: P and C).
7. When using the servo amplifier of 11k to 22kW, make sure to connect P
1
and P( ). (Factory-wired.)
8. Stepdown transformer is required for coil voltage of magnetic contactor more than 200V class servo amplifiers.

(b) Example of selecting the wire sizes
When connecting multiple servo amplifiers, always use junction terminals for wiring the servo amplifier
terminals P, N. Also, connect the servo amplifiers in the order of larger to smaller capacities.
