Autotuning Mode - YASKAWA Varispeed E7 Instruction Manual And Parameter Description

Autotuning Mode

Autotuning automatically measures and sets the motor line-to-line resistance of the motor and motor cable to
compensate the voltage drop and thereby to achieve the best performance.
Example of Operation
Set the motor rated output power (in kW) and the motor rated current, specified on the motor nameplate and
then press the RUN key. The motor is automatically run and the line-to-line resistance is measured.
Constants can be changed from the setting displays. Use the Increment, Decrement, and Shift/RESET keys to
change the setting. The user constant will be written and the display will be returned to monitor display when
the DATA/ENTER key is pressed.
The following example shows the autotuning procedure.
