Configure a sequence that will shut off main circuit power at the follow cases.
FR-CV or servo amplifier alarm occurs.
EM1 (forced stop 1) turns off.
For the servo amplifier, configure a sequence that will switch the servo-on after the FR-CV is ready.
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.
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.
When using the servo amplifier of 7 kW or less, make sure to disconnect the wiring of built-in regenerative resistor (5 kW or
less: P+ and D, 7 kW to 7 kW: P+ and C).
Set [Pr. PA04] to "0 0 _ _" to enable EM1 (Forced stop 1).
When wires used for L11 and L21 are thinner than wires used for L1, L2, and L3, use a molded case circuit breaker.
(4) Selection example of wires used for wiring
POINT
Selection condition of wire size is as follows.
Wire type: 600 V Polyvinyl chloride insulated wire (IV wire)
Construction condition: One wire is constructed in the air.
(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.

2) Grounding
For grounding, use the wire of the size equal to or greater than that indicated in the following
table, and make it as short as possible.

5. When using the FR-CV, disconnect between P3 and P4 terminals.
6. Set [Pr. PA04] to "0 0 _ _" to enable EM1 (Forced stop 1).
7. When wires used for L11 and L21 are thinner than wires used for L1, L2, and L3, use a molded case circuit breaker.
