11.19.2 P
recautions
Set the FR-XC-(H) to the common bus regeneration mode by turning on switch 1 of the function
selecting switch (SW2).
Do not supply power to the main circuit power supply terminals (L1/L2/L3) of the servo amplifier. Doing
so may fail the servo amplifier and the FR-XC-(H).
Connect the polarities of the DC power supply between the FR-XC-(H) and the servo amplifier correctly.
Failing to do so may fail the FR-XC-(H) and the servo amplifier.
For 400 V, use the rated voltage and permissible fluctuation of the input power supply within the
following range.
Rated voltage: 3-phase 380 V to 480 V, 50 Hz/60 Hz
Permissible fluctuation: 3-phase 323 V to 528 V, 50 Hz/60 Hz
11.19.3 Servo amplifier settings
When using the FR-XC-(H), set the parameters as follows.
[Pr. PA02]: "_ _ 0 1"
[Pr. PA04]: "0 0 _ _"
[Pr. PC20]: "_ _ _ 1"

11.19.4 Capac
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.)
