ity selection
(1) Selection conditions
The multifunction regeneration converter FR-XC-(H) can be used with 200 V class servo amplifiers with
capacities of 100 W to 22 kW and 400 V class servo amplifiers with capacities of 600 W to 22 kW. Select
a multifunction regeneration converter based on the following selection conditions.
Number of servo amplifiers to be connected to one FR-XC-(H) is 10 or less
Total capacity of servo amplifiers [kW] ≤ Total capacity of servo amplifiers that can be connected to the
FR-XC-(H) [kW]
Effective value of the total servo motor output power [kW] ≤ Continuous output of the FR-XC-(H) [kW]
Maximum value of the total servo motor output power [kW] ≤ Instantaneous maximum output of the
FR-XC-(H) [kW]

(a) Calc
ulate the running power and regenerative power from the servo motor speed and torque with the
following formulas.
For rotary servo motors
Running power and regenerative power [W] = Servo motor speed [r/min] × Torque [N•m]/9.55
For linear servo motors
Running power and regenerative power [W] = Servo motor speed [m/s] × Thrust [N]
(Running power is indicated by positive values, and regenerative power is indicted by negative
values.)

Select a multifunction regeneration converter based on the selection conditions.
Number of servo amplifiers: 4 ≤ 10
Number of servo amplifiers OK.
Total capacity of servo amplifiers [kW] = 5 kW + 5 kW + 11 kW + 22 kW = 43 kW

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 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 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. If the
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, 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.

8. Remove the R1/L11 and S1/L21

9. Do not connect an

to the P4 terminal of the FR-XC.
10. Install a fuse on each wire between the FR-XC 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-wi
