Analog input fault

Analog Input Fault

Mitsubishi Electric · FR-D700 Basic Inverter

What does Analog input fault mean?

A voltage (or current) has been incorrectly applied to terminal 4 due to a mismatch between the Pr. 267 Terminal 4 input selection setting and the physical voltage/current input switch position. This incorrect configuration can lead to erroneous frequency commands, inaccurate control, or potential damage to the inverter's analog input circuitry.

Complete Troubleshooting Guide

  1. 1

    If intending to use current input, ensure the voltage/current input switch is set to the 'I' position and provide a current frequency command.

  2. 2

    If intending to use voltage input, set Pr. 267 Terminal 4 input selection accordingly and ensure the voltage/current input switch is set to the 'V' position.
