Note 1. 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.
2. For the servo amplifier, configure a sequence that will switch the servo-on after the FR-CV is ready.
3. 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.
4. 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 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.
5. 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: P+ and C).
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.
P4
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.
