
For the FR-F820-03160(75K) or higher, the FR-F840-01800(75K) or higher, always connect a DC reactor (FR-HEL), which is available as an option. (To select a DC
reactor, refer to page 25, and select one according to the applicable motor capacity.)
When a DC reactor is connected to the FR-F820-02330(55K) or lower or the FR-F840-01160(55K) or lower, if a jumper is installed across the terminals P1 and P/+,
remove the jumper before installing the DC reactor.

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 Instruction Manual (Detailed).)

It is recommended to use 2 W 1 kΩ when the frequency setting signal is changed frequently.
 Do not use terminals PR and PX. Do not remove the jumper connected to terminals PR and PX.

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

The 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.

No function is assigned in the initial status. Assign the function using Pr.186 CS terminal function selection. (Refer to
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.
