Digital Operator Display Probable Cause Corrective Action
Er - 01
Fault
• There is an error in the data input for autotuning.
• There is an error in the relationship between the motor
output and the motor rated current.
• Check input data.
• Check iQpump and motor capacity.
• Check motor rated current.
Er - 02
Minor Fault
A minor fault is detected during auto-tuning.
• Check input data.
• Check wirings and around the machine.
• Check the load.
Er - 03
STOP key

range.
• Check input data.
• Check motor wiring.
• If a motor and a machine are connected, disconnect the
motor from the machine.
Er - 12
I-det. Circuit
• Current flow exceeded the motor rated current.
• Current detection value symbol was reversed.
• Any of U/TI, V/T2, and W/T3 has open-phase.
• Check current detection circuit, wiring and mounting
procedure.
Er - 13
Leakage Inductance Fault
Auto-tuning did not finish within the set time.
Tuning result was outside the acceptable parameter setting
range.
• Check motor wiring.
End - 3
Data Invalid
