Error Displays during Autotuning
If the STOP Key is pressed during autotuning or a measurement error is detected, an error will be displayed
and autotuning will be canceled. Details on the error will be displayed on the Digital Operator. The fault con-
tact output and the alarm output will not operate.
Refer to Errors During Autotuning in Chapter 7 Troubleshooting for details.
Stationary Autotuning for Line-to-Line Resistance Only (T1-01 = 2)
Stationary autotuning for line-to-line resistance only can be used in any control method. This is the only auto-
tuning possible for V/f control and V/f control with PG modes.
Autotuning can be used to prevent control errors when the motor cable is long (50 m or longer) or the cable
length has changed since installation or when the motor and Inverter have different capacities.
Set T1-01 to 2, and then press the RUN Key on the Digital Operator. The Inverter will supply power to the sta-
tionary motor for approximately 20 seconds and the Motor Line-to-Line Resistance (E2-05) and cable resis-
tance will be automatically measured.

1. Power will be supplied to the motor when stationary autotuning for line-to-line resistance is performed
even though the motor will not turn. Do not touch the motor until autotuning has been completed.
2. When performing stationary autotuning connected to a conveyor or other machine, ensure that the
holding brake is not activated during autotuning.
