Start autotuning.
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 2 (T1-01 = 4)
If using Inverters for applications with constant loads such as for elevators, or with a motor load ratio exceed-
ing 30% at startup, and rotational autotuning without loads cannot be performed, perform stationary autotun-
ing 2 (T1-01=4).
Stationary autotuning 2 is used for open-loop vector control and flux vector control. Set T1-04 to 4, and Motor
no-load current (T1-09) will be added as a setting item. Input the data from the nameplate. Be sure to input the
value or motor no-load current (motor exciting current) from motor examination results to T1-09. After auto-
tuning, the value of T1-09 will be written in E2-03. When not setting T1-09, the value of Yaskawa standard
motor’s no-load current will be written in E2-03.

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