Note 1. Configure a sequence that will shut off main circuit power at a forced stop or at FR-CV 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 is ready.
4. For the FR-CV, 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 forced stop input of the servo system controller if an alarm occurs in
the FR-CV. When the servo system controller does not have a forced stop input, use the forced stop input of the servo
amplifier to make a stop as shown in the diagram.
6. For 7kW or less servo amplifier, always remove the wiring (3.5kW or less: across P-D, 5k 7kW: across P-C) of built-in
regenerative resistor.
7. When using the servo amplifier of 11k to 22kW, make sure to connect P
1
and P. (Factory-wired.)
8. Refer to section 1.3 for the power supply specification.
(3) Wires used for wiring
(a) Wire sizes
1) Across P-P, N-N
The following table indicates the connection wire sizes of the DC power supply (P, N terminals)
between the FR-CV and servo amplifier. The used wires are based on the 600V vinyl wires.
