Note If the motor cable changes to 50 m or longer for the actual installation, perform stationary autotuning for the line-to-line resistance only on-
site.
* 1. Use rotational autotuning to increase autotuning accuracy whenever it is okay for the motor to be operated.
* 2. If there is a reduction gear between the motor and PG, set the reduction ratio in F1-12 and F1-13.
