
For the FR-A860-01440 or higher, and when a 75 kW or higher motor is used, always connect a DC reactor, which is available as an option. (To select a DC reactor,
refer to the Instruction Manual (Detailed), and select one according to the applicable motor capacity.) When connecting a DC reactor, if a jumper is installed across
terminals P1 and P/+, remove the jumper before installing the DC reactor. (The jumper is not installed for the FR-A860-01440 or higher.)

When using separate power supply for the control circuit, remove the jumper between R1/L11 and S1/L21.

The function of these terminals can be changed with the input terminal assignment (Pr.178 to Pr.189). (Refer to

Terminal JOG is also used as the pulse train input terminal. Use Pr.291 to choose JOG or pulse.

Terminal input specifications can be changed by analog input specification switchover (Pr.73, Pr.267). To input a voltage, set the voltage/current input switch OFF. To
input a current, set the voltage/current input switch ON. Terminals 10 and 2 are also used as a PTC input terminal. (Pr.561) (Refer to the FR-A800 Instruction Manual
(Detailed).)

It is recommended to use 2 W 1 kΩ when the frequency setting signal is changed frequently.

A brake resistor is provided with the FR-A860-00090 or lower. Connect the provided brake resistor to terminals P3 and PR as required.

Connect a brake resistor across terminals P3 (P/+) and PR. (Terminal PR is equipped in FR-A860-01080 or lower.) Install a thermal relay to prevent overheating and
damage of discharging resistors. (Refer to the FR-A800 Instruction Manual (Detailed).)

The function of these terminals can be changed with the output terminal assignment (Pr.195, Pr.196). (Refer to

The function of these terminals can be changed with the output terminal assignment (Pr.190 to Pr.194). (Refer to

Terminal F/C (FM) can be used to output pulse trains as open collector output by setting Pr.291.

Not required when calibrating the scale with the operation panel (FR-LU08) or the parameter unit (FR-PU07).

The option connector 2 cannot be used because the Ethernet board is installed in the initial status. The Ethernet board must be removed to install a plug-in option to the
option connector 2. (However, Ethernet communication is disabled in that case.)
NOTE
• To prevent a malfunction due to noise, keep the signal cables 10 cm or more away from the power cables. Also, separate the main circuit cables at the input side from
the main circuit cables at the output side.
• After wiring, wire offcuts must not be left in the inverter. Wire offcuts can cause an alarm, failure or malfunction. Always keep the inverter clean. When drilling mounting
holes in an enclosure etc., take caution not to allow chips and other foreign matter to enter the inverter.
• Set the voltage/current input switch correctly. Incorrect setting may cause a fault, failure or malfunction.
• Terminals S1, S2, SIC, So (SO), and SOC are for manufacturer setting. Do not connect anything to these. Doing so may cause an inverter failure.
Do not remove the shorting wires across terminals S1 and PC, terminals S2 and PC, and terminals SIC and SD. Removing either shorting wire disables the inverter
operation.
