Auto-Tuning Codes, Causes, and Possible Solutions
Table 5.5 Auto-Tuning Codes, Causes, and Possible Solutions
LED Operator Display Error Name
End1 Excessive V/f Setting. Displayed after Auto-Tuning is complete.
Cause Possible Solutions
The torque reference exceeded
20% during Auto-Tuning.
• Before Auto-Tuning the drive, verify the information written on the motor
nameplate and enter that data to T1-03 through T1-05.
• Enter proper information to parameters T1-03 to T1-05 and repeat Auto-Tuning.
• If possible, disconnect the motor from the load and perform Auto-Tuning.
The no-load current exceeded
80% of the drive rated current
during Auto-Tuning.
End2
Motor Iron-Core Saturation Coefficient. Detected only during Rotational
Auto-Tuning and displayed after Auto-Tuning is complete.
Cause Possible Solutions
Motor data entered during
Auto-Tuning was incorrect.
• Motor data entered to the T1 parameters does not match the information written
on the motor nameplate.
• Restart Auto-Tuning and enter the correct information.
Auto-Tuning calculated values
outside the parameter setting
range, assigning the iron-core
saturation coefficient (E2-07,
-08) a temporary value.
• Check and correct faulty motor wiring.
• Disconnect the motor from machine and perform Rotational Auto-Tuning.
End3 Rated Current Setting Alarm (displayed after Auto-Tuning is complete)
Cause Possible Solutions
• The motor line-to-line
resistance and the
motor-rated current are not
consistent with one another.
• The correct current rating
printed on the nameplate was
not entered into T1-04.
• Check the setting of parameter T1-04.
• Check the motor data and repeat Auto-Tuning.
Er-01 Motor Data Error
Cause Possible Solutions
Motor data or data entered during
Auto-Tuning was incorrect.
• Check that the motor data entered to T1 parameters matches motor nameplate
input before Auto-Tuning.
• Start Auto-Tuning over again and enter the correct information.
