Pr.1219
Status
Tension PI gain tuning is in progress.
a Refer to the manipulated amount when the tuning is started, and use the setting in Pr.1215 Limit cycle output upper limit to
increase/decrease the manipulated amount to adjust the amplitude of the measured value.
Calculate PI gain.
b
The PI gain response level can be set with Pr.1226 Tension PI gain tuning response level setting.
• The tuning results are applied to the following parameters.
