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.)
