PID set point (Pr.133)
• Set the target position (neutral position) of the dancer roll in Pr.133 PID action set point.

• If the position signal input from the dancer roll through terminal 1 is 10 V at the upper limit position, -10 V at the lower limit
position, and 0 V at the neutral position (target position), set 500% in Pr.133. If the signal is -5 V at the neutral position
(target position), set 450% in Pr.133. A voltage from -10 V to 10 V can be input through terminal 1.
