What to do if my Fuji Electric FRENIC-Multi Inverter shows an enable circuit failure?
- M
  Melissa LucasJul 30, 2025
  If your Fuji Electric Inverter shows an enable circuit failure, first ensure the interface PCB is correctly mounted. If that's not the issue, check that the safety switch output levels (EN1/EN2) are consistent (both High/High or Low/Low). Power cycle the inverter to clear the alarm. If the problem persists and a single enable circuit failure is detected, the inverter requires repair; contact your Fuji Electric representative, as the 'Reset alarm' terminal command RST won't resolve it.

Why does my Fuji Electric FRENIC-Multi Inverter show overheat protection?
- B
  Brian YatesAug 5, 2025
  The Fuji Electric Inverter might show overheat protection because the heat sink temperature is too high. This can happen if the inverter fan isn't working or if the inverter is overloaded.

What causes undervoltage protection in Fuji Electric Inverter?
- R
  Robin ReedAug 10, 2025
  Undervoltage protection in Fuji Electric Inverters is activated when the voltage in the DC link is too low (200 V for 200 V class inverters; 400 V for 400 V class inverters). Note: if F14=4 or 5, this alarm won't activate when the DC link voltage is low.

What does electronic thermal overload motor 1 mean on a Fuji Electric FRENIC-Multi Inverter?
- S
  smithtimothyAug 15, 2025
  The 'Electronic thermal overload motor 1' message on your Fuji Electric Inverter indicates that the inverter is protecting the motor according to the electronic thermal overload protection settings. Specifically: - F10 (A06) =1 is for general purpose motors. - F10 (A06)=2 is for inverter motors. - F11 (A07) defines the operation level (current level). - F12 (A08) defines the thermal time constant. Note: F functions are for motor 1 and A functions are for motor 2.

What to do if PTC thermistor stops Fuji Electric Inverter?
- F
  fmendozaAug 20, 2025
  If the PTC thermistor stops your Fuji Electric Inverter to protect the motor, ensure the thermistor is connected between terminals [C1] and [11]. Also, verify the slide switch position and that functions H26 (enable) and H27 (level) are correctly set.
