Dancer optimization
(continued)
5.
Adjust the D pot in small steps, checking for dancer overshoot
at each step. Do this until the overshoot is eliminated. The
direction to adjust D for no overshoot is system dependent.
6.
Repeat steps (4) and (5) until the overshoot cannot be
eliminated using the D pot, or until the P pot is full clockwise.
7.
Decrease the P pot by the amount necessary to eliminate the
overshoot.
Adjustment is now complete for the dancer operating in PD mode.
PID mode
The next steps complete the tuning of the dancer operating in PID
mode.
1.
With a roll diameter near full roll and the machine stopped,
set the F switch to PID.
2.
Run the machine and adjust the pot to center the dancer roll.
3.
Decrease the pot by rotating counter-clockwise in small steps
checking for dancer overshoot at each step. Do this until
overshoot is obtained.
4.
Increase the pot by the amount necessary to eliminate the
overshoot.
Adjustment is now complete for the dancer operating in PID mode.
