response
Cause/solution
Error 01
Overcurrent in output
stage
Output stage
inhibit / locked
Short circuit on inverter output.
→
Check the connection between the inverter output and the motor as
well as the motor winding for short circuits.
Reset error by switching the unit off or via error reset function.
Error 06
