Stop due to overvoltage
•
Input power voltage too high or deceleration too fast.
•
The currents generated could damage the inverter.
Troubleshooting:
1. Ensure that the power voltage of terminals L and N is correct.
2. Press STOP/RESET on the inverter.
3. Check the RUNNING SPEED, inverter parameter A021, and reduce the speed, if necessary.
4. Check the MINIMUM STOP SPACE in chart 1 in section 6.2 FINAL ADJUSTMENT OF THE LIMIT SWITCHES, and, if necessary,
increase the stop space by adjusting the limit switches.
5. Check the DECELERATION SPACE, as shown in section 6.2 FINAL ADJUSTMENT OF THE LIMIT SWITCHES, and, if necessary,
increase the deceleration space by adjusting the limit switches.
6. Check the DECELERATION set in the parameter F003, as shown in section 6.2 FINAL ADJUSTMENT OF THE LIMIT SWITCHES,
paragraphs 13 and 14, and, if necessary, increase the deceleration value.
NOTE: In case of other ERROR warnings, wait (10 sec) for the inverter to reset automatically.
If the ERROR persists, press STOP/RESET
