Connection of the DC reactor
• When using the DC reactor, connect it across terminals P/+ and P1.
For the FR-A860-01080 or lower, the jumper connected across terminals P/+ and P1 must be removed. Otherwise, the
reactor will not be effective.
• Select a DC reactor according to the applied motor capacity. (Refer to
• For the FR-A860-01440 or higher, and when a 75 kW or higher motor is used, always connect a DC reactor.
• Select a DC reactor according to the following table.
Motor capacity (kW)


The power supply frequency of 60 Hz is assumed.

Class H or higher insulation is recommended.
Select a DC reactor for which its L value does not fall to 50% or below when the inverter overload current rating is 150% (ND rating).
NOTE
• The wiring distance must be within 5 m.
• As a reference, the cable gauge for the connection must be equal to or larger than that of the power supply cables (R/L1, S/
L2, T/L3) and the earthing (grounding) cable. (Refer to
