Autotuning Mode - Omron VARISPEED L7 Manual

Autotuning Mode

Autotuning automatically measures and sets the required motor data in order to achieve the maximum perfor-
mance. Always perform autotuning before starting operation when using the vector control modes.
When V/f control has been selected, stationary autotuning for line-to-line resistance can be selected only.
When the motor cannot be operated (e.g. if the ropes cannot be removed from the traction sheave), and Open
Loop or Closed Loop Vector Control shall be used, perform stationary autotuning.
Example of Operation for V/f control
The tuning method for V/f control is fixed to the measurement of the terminal resistance (T1-01=1). Input the
the rated output power and the rated current specified on the nameplate of the motor and then press the RUN
key. The motor data are measured automatically.

Always set the above items. Otherwise autotuning cannot be started, e.g. it cannot be started from the motor
rated voltage input display.
A parameter can be changed from the setting displays using the Increment, Decrement, and Shift/RESET
keys. The parameter is saved when the DATA/ENTER key is pressed.
The following flowchart shows a V/f control Autotuning example.
