Terminal connection diagrams

The function of these terminals can be changed with the input terminal assignment (Pr.178 to Pr.189). (Refer to the FR-A800 Instruction Manual
(Detailed).)

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 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 k when the frequency setting signal is changed frequently.

The function of these terminals can be changed with the output terminal assignment (Pr.195, Pr.196). (Refer to the FR-A800 Instruction Manual
(Detailed).)

The function of these terminals can be changed with the output terminal assignment (Pr.190 to Pr.194). (Refer to the FR-A800 Instruction
Manual (Detailed).)

Do not change the initially set ON (enabled) position of the EMC filter ON/OFF connector in the case of the inverter with a built-in C2 filter. The
Class C2 compatibility condition is not satisfied with the EMC filter OFF. The FR-A846-00250(7.5K)-C2 to FR-A846-00470(18.5K)-C2 are not
provided with the EMC filter ON/OFF connector. The EMC filter is always ON.
NOTE
• To prevent a malfunction due to noise, keep the signal cables 10 cm (3.94 inches) 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 a wall or the side of the enclosure etc., take caution not to allow chips and other foreign
matters to enter the inverter.
• Set the voltage/current input switch correctly. Incorrect setting may cause a fault, failure or malfunction.
