What to do if my INVT Inverter displays OH1?
- H
  hmullinsAug 23, 2025
  If your INVT Inverter displays 'OH1', it indicates a sudden overcurrent. Refer to the overcurrent solution. Other causes include a short-circuited output phase (reconfigure), a damaged ventilation duct or fan (clear the duct and change the fan), high ambient temperature (reduce it), loose wiring on the control board (check and rewire), damage to the assistant circuit causing undervoltage (ask for support), a direct bridge arm issue in the power module (ask for support), or an abnormal control board (ask for support).

What does OUT1 error mean on INVT CHV180-7R5G-4?
- D
  Daniel RogersAug 31, 2025
  If your INVT Inverter displays 'OUT1', it may be due to the Acc/Dec time being too short (increase Acc/Dec time), an IGBT module fault (ask for support), malfunction caused by interference (inspect external equipment and eliminate interference), or improper grounding.

What to do if INVT CHV180-7R5G-4 displays OL2?
- R
  Rhonda GrayAug 30, 2025
  If your INVT Inverter displays 'OL2', it could be caused by a short Acc time (increase Acc time or select a bigger capacity inverter), restarting the rotating motor (avoid restarting after stopping), low input voltage (select a bigger capacity inverter), or an excessively heavy load.

What does OV1 error mean on INVT CHV180-7R5G-4?
- T
  Teresa MooreAug 29, 2025
  If your INVT Inverter displays 'OV1', it could be due to abnormal input voltage (check the input power) or restarting the rotating motor after a sudden power off (avoid restarting after stopping).

Why is my INVT CHV180-7R5G-4 Inverter showing OL1 error?
- B
  Brian MyersAug 28, 2025
  If your INVT Inverter displays 'OL1', it might be due to low voltage (check the input power), an improper motor rated current (reset the rated current of the motor), motor stalling or excessive load transients (check the load and adjust the torque boost), reverse direction of the encoding disk or prolonged low-speed operation in open-loop vector control (adjust the direction of the encoding disk signal), or a motor driving a heavy load at low speed for an extended period (select a proper motor).

What causes OC1 fault on INVT Inverter?
- E
  Eric RiveraAug 27, 2025
  If your INVT Inverter displays 'OC1', it could be because the acceleration time is too short (increase Acc time), the voltage is too low (check the input power), or the inverter power is too low (select bigger capacity inverter).

What does OC2 mean on my INVT CHV180-7R5G-4?
- L
  Lisa JenkinsAug 27, 2025
  If your INVT Inverter displays 'OC2', it could be due to a short deceleration time (increase the Dec time), high load inertia torque (add proper braking kits), or the inverter power being too low (select a bigger capacity inverter).

Why does my INVT Inverter show OV2 error?
- R
  Robert CrosbyAug 26, 2025
  If your INVT Inverter displays 'OV2', it could be due to a short deceleration time (increase the deceleration time), high load inertia (increase proper braking kits), or abnormal input voltage (check the input power).

What causes OC3 error on INVT CHV180-7R5G-4?
- K
  Kimberly MartinezAug 25, 2025
  If your INVT Inverter displays 'OC3', it could be due to load transients, abnormal load (check the load and reduce the transients), low voltage (check the input power), insufficient inverter power (select a bigger capacity inverter), or issues with the encoding disk in a closed-loop system running at high speed (check the encoding disk and wiring).
