 Tension PI gain tuning adjustment parameter
• Before performing tension PI gain tuning, adjust the following parameters as required.
 : Setting required, —: Setting not required
∗1
The setting can be adjusted. Adjust the setting as required.
∗2
After the tuning, the result is set automatically.
∗3
If the approximate setting value is unknown, use the result of the PI gain tuning during stopping.
∗4
The PGT signal can be also used for starting or terminating the tuning.
