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. For the FR-CV-H, 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-H. 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 FR-CV-H, always disconnect wiring 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.
8. 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.
