■400 V class
When using the servo amplifier of 7 kW or less, be sure to disconnect the wiring of built-in regenerative
resistor (3.5 kW or less: P+ and D, 5 kW/7 kW: P+ and C).

*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 emergency stop input of the controller if an alarm occurs in the FR-CV-H. When the
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.
*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.
