Description
Set the timeout time for tension PI gain tuning.
Set the output upper limit for the amount of positive
manipulation for tension PI gain tuning.
Set the hysteresis of the set point to perform tension PI
gain tuning.
Set to indicate the condition of tension PI gain tuning,
or start/terminate the tuning.
Set the target amplitude for the limit cycle. Start tuning
with a small value and gradually increase the value
while making sure that tuning causes no problem.
Set the amount for manipulation to fit the value to the
set point.
Set the response level of tension PI gain tuning in the
range from "1" (slow) to "7" (fast).
