What to do if Emotron AFR 2.0 shows 'Over curr F' error?
- L
  Latoya KingAug 18, 2025
  If the Emotron Industrial Electrical unit displays an 'Over curr F' error, it indicates that the current exceeds the peak VSI current. This can be due to too high load, excessive load change, a soft short-circuit between phases or phase to earth, or poor or loose cable connections. To resolve this, check the main supply voltage, examine line and earth cable connections for issues, and inspect the motor housing and cable connections for water or moisture.

What to do if Emotron AFR 2.0 Industrial Electrical shows 'Under voltage' error?
- Y
  yschmidtAug 21, 2025
  If the Emotron Industrial Electrical unit shows an 'Under voltage' error, it means the DC Link voltage is too low. This can be caused by too low or no supply voltage, or a mains voltage dip due to starting other major power-consuming machines on the same line. To fix this, ensure all three phases are properly connected and the terminal screws are tightened, check that the DC supply voltage is within the limits of the VSI, and try using other mains supply lines if the dip is caused by other machinery.

  If you're getting an 'Over temp' error on your Emotron Industrial Electrical, it means the heatsink temperature is too high. This could be due to a high ambient temperature, insufficient cooling, excessive current, or blocked fans. Check the cooling of the VSI cabinet, ensure the built-in fans are working correctly and switch on automatically when the heatsink temperature gets too high, verify the VSI and motor ratings, and clean the fans.

Why does Emotron Industrial Electrical show 'Over volt (Mains)' error?
- T
  Tiffany McdonaldAug 26, 2025
  The 'Over volt (Mains)' error on your Emotron Industrial Electrical indicates that the DC Link voltage is too high due to an excessive mains voltage. To address this, check the main supply voltage and try to eliminate the source of interference or switch to different main supply lines.

What causes 'Sync Error' in Emotron AFR 2.0 Industrial Electrical?
- A
  alex81Aug 28, 2025
  A 'Sync Error' in Emotron Industrial Electrical indicates overcurrent during synchronization to the supply. To resolve this, check the mains supply voltage, LCL-filter and cables, circuit breaker and main contactor. Also, verify the supply parameters and check if the DC-link is not already loaded.

What causes 'Over volt G(enerator)' error in Emotron Industrial Electrical?
- E
  Erica DicksonSep 1, 2025
  The 'Over volt G(enerator)' error in Emotron Industrial Electrical indicates that the DC Link voltage is too high. To resolve this, check the main supply voltage and try to eliminate the interference or use other main supply lines.

What does 'DC link error' mean on Emotron Industrial Electrical?
- I
  Isabel BowersSep 4, 2025
  A 'DC link error' on Emotron Industrial Electrical means the DC link voltage ripple exceeds the maximum level. To resolve this, make sure all three phases are properly connected and that the terminal screws are tightened, check that the DC supply voltage is within the limits of the VSI, and try to use other mains supply lines if a dip is caused by other machinery.

What does 'Supply error' mean in Emotron Industrial Electrical?
- A
  Ashley SchwartzSep 6, 2025
  A 'Supply error' in Emotron Industrial Electrical indicates that no synchronization current pulse was detected. To address this, check the mains supply voltage, LCL-filter and cables, and the circuit breaker and main contactor.

How to resolve 'Sup Chk Err' on Emotron Industrial Electrical?
- C
  camachotylerSep 8, 2025
  To resolve a 'Sup Chk Err' on your Emotron Industrial Electrical, check the mains supply voltage, LCL-filter and cables, circuit breaker and main contactor. Also, check the wiring of the voltage sensor (if 'Sync option' is used) and re-do the supply ID-Run.
