POINT
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).

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, confi
g
ure a sequence that will switch the servo-on after the FR-CV-H is read
y
.
3. 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 dia

6. When wires used for L11 and L21 are thinner than wires used for L1, L2, and L3, use a molded-case circuit breaker.

(b) Example of selecting the wire sizes
When connecting multiple servo amplifiers, always use junction terminals for wiring the servo
amplifier terminals P4, N-. Also, connect the servo amplifiers in the order of larger to smaller
capacities.
