For the FR-F820-03160(75K) or higher and the FR-F840-01800(75K) or higher, always connect the DC reactor option FR-HEL. Refer to
to select the right DC reactor according to the applicable motor capacity.
To connect a DC reactor, remove the jumper installed across terminals P1 and P/+ before installing the DC reactor. (A jumper is not installed in
the FR-A820-03160(75K) or higher and the FR-A840-01800(75K) 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 using the Input terminal function selection (Pr.178 to Pr.189). (Refer to
Terminal JOG is also used as a 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 corresponding
switch of the voltage/current input selection switch assembly to the OFF position. To input a current, set the switch to the ON position. Terminals
10 and 2 are also used as a PTC input terminal (Pr.561). (Refer to
It is recommended to use 2 W 1 kΩ potentiometer when the frequency setting signal is changed frequently.
Do not use terminals PR and PX. Whether a jumper is provided across the terminals depends on the inverter model. (Refer to
Do not connect the DC power supply (under DC feeding mode) to terminal P3.
The function of these terminals can be changed using the Output terminal function selection (Pr.195 or Pr.196). (Refer to
*10 The function of these terminals can be changed using the Output terminal function selection (Pr.190 to Pr.194). (Refer to
*11 Terminal FM can be used to output pulse trains as open collector output by setting Pr.291.
*12 Not required when calibrating the scale with the operation panel.
*13 No function is assigned in the initial setting. Assign the function using Pr.186 CS terminal function selection. (Refer to
• To prevent a malfunction due to noise, keep the signal cables 10 cm or more away from the power cables. Also, keep the
cables of the main circuit for input and output separated.
• After wiring, wire offcuts must not be left in the inverter.
Wire offcuts can cause a fault, 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 switches of the voltage/current input selection switch assembly correctly. Incorrect setting may cause a fault, failure or
