Multifunction regeneration converter (FR-XC-(H))
For details on the multifunction regeneration converter (FR-XC-(H)), refer to "FR-XC Instruction Manual (IB-
0600668ENG)".
Precautions
• Set the FR-XC-(H) to the common bus regeneration mode by turning on the switch 1 of the function selecting switch (SW2).
• Do not apply 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.
• Regenerative capacity cannot be enhanced even if two or more FR-XC-(H) are connected.
• When using the FR-XC-H, the rated voltage and the permissible fluctuation of the input power supply must be within the
following range.
Rated voltage: 3-phase, 380 to 480 V, 50 Hz/60 Hz
Permissible fluctuation: 3-phase, 323 to 528 V, 50 Hz/60 Hz
Servo amplifier settings
When using the FR-XC-(H), set the parameters as follows.
• [Pr. PA02.0-1]: 01/[Pr. PA02.4]: 0
• [Pr. PA04.2]: 0/[Pr. PA04.3]: 0
Capacity selection
Selection conditions
The multifunction regeneration converter FR-XC-(H) can be used with 200 V class servo amplifiers with capacities of 100 W to
7 kW and 400 V class servo amplifiers with capacities of 600 W to 3.5 kW. Use the following conditions to select a
multifunction regeneration converter.
• 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 total output power of servo motors [kW]
≤
Continuous output of the FR-XC-(H) [kW]
• Maximum value of total output power of servo motors [kW]
≤
Instantaneous maximum output of the FR-XC-(H) [kW]
*1 Values in parentheses are when six servo amplifiers or less are connected.
