Status
Operate as per the amount set in Pr.1223 Manipulated amount for operation, to fit PID value to the setting of Pr.133 PID
a
action set point.
b When the PID value reaches the Pr.1222 setting, tension PI gain tuning starts.
c Tension PI gain tuning is in progress.
Calculate PI gain.
d
The PI gain response level can be set with Pr.1226 Tension PI gain tuning response level setting.
e Operate as per the amount set in Pr.1223 to lower the PID measured value.
• The tuning results are applied to the following parameters.
