Err display on operation panel
Err display appears on the operation panel but the inverter continues operating normally.
It seems that the situation does not fall under any error cause described in the Instruction Manual. Are there any possible causes?
How can I clear this Err display?

Answer
The following causes are probable for this Err display:
- Operation error (for example, you tried to input a value other than the available range of parameter values)
- RES signal is ON
- Communication fault due to connection fault between the inverter and operation panel
If the inverter can operate normally, the RES signal should be OFF. Check the operation procedure as well as check for a contact fault between the inverter and operation panel.
If both are correct, the operation panel or inverter may be faulty.
Contact your local distributor.
