Why does my INVT CHV180-7R5G-4 Inverter trip the input switch when running?
- G
  gracerogersSep 4, 2025
  If your INVT Inverter displays 'The inverter displays normally when power on, but switch at the input side trips when running', inspect whether the output side of inverter is short circuit. If yes, ask for support. Inspect whether ground fault exists. If yes, solve it. If trip happens occasionally and the distance between motor and inverter is too far. It is recommended to install output AC reactor.

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).

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).

- 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).

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).

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 does EEP error mean on INVT CHV180-7R5G-4 Inverter?
- A
  Andrew LambSep 9, 2025
  If your INVT Inverter displays 'EEP', it could be due to a read/write fault of control parameters (press STOP/RST to reset) or EEPROM damage (ask for support).

  trevorwatkinsSep 10, 2025
  If your INVT Inverter displays 'OV3', it could be due to abnormal input voltage changes (install input reactor) or high load inertia (add proper braking kits).

What should I do if my INVT Inverter is running but the motor won’t move?
- N
  Nicole ClaySep 3, 2025
  If your INVT Inverter displays 'Motor doesn’t move after inverter running', inspect if there is balanced three-phase output among U, V, and W. If yes, then motor could be damaged, or mechanically locked. Please solve it. If the output is unbalanced or lost, the inverter drive board or the output module may be damaged. ask for support.

How to troubleshoot no display on INVT CHV180-7R5G-4 Inverter after power on?
- L
  Laura RaySep 1, 2025
  If your INVT Inverter displays 'No display after power on', inspect whether the voltage of power supply is the same as the inverter rated voltage or not with multi-meter. If the power supply has problem, inspect and solve it. Also inspect whether the three-phase rectify bridge is in good condition or not. If the rectification bridge is burst out, ask for support. Check the CHARGE light. If the light is off, the fault is mainly in the rectify bridge or the buffer resistor. If the light is on, the fault may be lies in the switching power supply. Please ask for support.
