Tension PI gain tuning during stopping
• The tuning results are applied to the following parameters.
Status
Tuning operation
a
Operate as per the amount set in
Pr.1223 Manipulated amount for operation
, to fit PID value to the setting of
Pr.133 PID
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.
d
Calculate PI gain.
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.
