  • Page 170 PPENDIX PID Set Up PID Loop The MD65 has a built-in PID (proportional, integral, differential) control loop. The PID loop is used to maintain a process feedback (such as pressure, flow or tension) at a desired set point. The PID loop works by subtracting the PID feedback from a reference and generating an error value.
  • Page 171 • When the PID Control Loop is disabled, the Commanded Speed is the Ramped Speed Reference. PID Feedback = Pressure Transducer Signal Pump PID Reference = Desired System Pressure Trim Control In Trim Control, the PID Output is added to the Speed Reference. In Trim mode, the output of the PID loop bypasses the accel/decel ramp as shown.
  • Page 172 • As tension increases or decreases during winding, the Speed Reference is trimmed to compensate. Tension is maintained near the Equilibrium set point. 0 Volts PID Reference = PID Feedback = Equilibrium Set Point Dancer Pot Signal 10 Volts Speed Reference PID Reference and Feedback PID Ref Sel (A132) is used to enable the PID mode (A132 does not equal 0;...

It will ignore any negative voltages and treat them like a zero.

  • Page 176 PID Gains The proportional, integral, and differential gains make up the PID regulator. • PID Prop Gain (A134) The proportional gain (unitless) affects how the regulator reacts to the magnitude of the error. The proportional component of the PID regulator outputs a speed command proportional to the PID error.
