Note 1. Configure a sequence that shuts off the main circuit power supply in the following situations:
When an alarm occurs in the FR-XC-H or servo amplifier
When EM1
(
Forced stop 1
)
is enabled.
2. Confi
g
ure a sequence that shifts the status to servo-on once the F
R
-XC-H is read
y
.
3. Ensure that the servo motor stops with a forced stop input of the servo amplifier when an alarm occurs in the FR-XC-H. If t
he
controller does not have an emer
g
enc
y
stop input, use the forced stop input of the servo amplifier to stop the servo motor.
4. When usin
g
the FR-XC-H, remove the wire between P3 and P4.
5. To use EM1
(
Forced stop 1
)
, set [Pr. PA04] to "0 0 _ _".
6. If wires used for L11 and L21 are thinner than wires used for L1, L2, and L3, use a molded-case circuit breaker.

purposes, the s

ured to use a sin

y
.
8. Remove the R1/L11 and S1/L21
j
umpers when usin
g
a dedicated power suppl
y
for the control circuit.
9. Do not connect an
y
thin
g
to the P4 terminal of the FR-XC-H.
10. Install a fuse on each wire between the FR-XC-H and servo amplifier.
11. Make sure to wire the built-in regenerative resistor when using servo amplifiers with a capacity of 7 kW or less. (factory-wired)
(
3.5 kW or less: between P+ and D, 5 kW/7 kW: between P+ and C
)

e size selection example (between P/+ and P4, between N/- and N-)
When connecting multiple servo amplifiers to the FR-XC, junction terminal blocks must be used for the
wiring to terminals P4 and N- on the servo amplifiers. Connect the servo amplifiers in order with the
largest capacity first.
