Note 1. Configure a sequence that will shut off main circuit power in the following.
An alarm occurred at FR-CV-H or servo amplifier.
EM1 (Forced stop 1) is enabled.
2. For the servo amplifier, configure a sequence that will switch the servo-on after the FR-CV-H is ready.
3. Configure a sequence that will make a stop with the forced stop input of the servo amplifier if an alarm occurs in the FR-CV-H.
4. When using FR-CV-H, always disconnect wiring between P3 and P4 terminals.
5. Set [Pr. PA04] to "0 0 _ _" to enable EM1 (Forced stop 1).
6. When wires used for L11 and L21 are thinner than wires used for L1, L2, and L3, use a molded-case circuit breaker.
7. The illustration of the 24 V DC power supply is divided between input signal and output signal for convenience. However, they
can be configured by one.
