Note 1. Configure a sequence that will shut off main circuit power in the following cases.
Alarm occurred in the FR-CV or the servo amplifier.
Emergency stop is activated.
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 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.
5. When using the servo amplifier of 11k to 22kW, make sure to connect P
1
and P. (Factory-wired.)
6. 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.
