Entering the PID Feedback Value

You can use two methods to input the PID feedback value to the drive.

• Use Single Feedback Signal

  Use Table 1 to select how the feedback signal is input to the drive for PID control.

  Table 1. PID Feedback Input Method

  PID Feedback Input Method	Setting Value
  MFAI terminal A1	Set H3-02 = B [PID Feedback].
  MFAI terminal A2	Set H3-10 = B.
  MFAI terminal A3	Set H3-06 = B.
  Pulse train input terminal RP	Set H6-01 = 1 [PID Feedback Value].

• Use Two Feedback Signals and Calculate the Deviation from the Difference between Those Signals

  Use Table 2 to select how the second feedback value is input to the drive. The drive calculates the deviation of the second feedback value. Set H3-02, H3-06, or H3-10 = 16 [Terminal A1/A3/A2 Function Selection = Differential PID Feedback] to enable the second feedback signal used to calculated the deviation.

  Table 2. PID Differential Feedback Input Method

  PID Differential Feedback Input Method	Setting Value
  MFAI terminal A1	Set H3-02 = 16 [Differential PID Feedback].
  MFAI terminal A2	Set H3-10 = 16.
  MFAI terminal A3	Set H3-06 = 16.

  Note:

  If you set two or more of H3-02, H3-06, and H3-10 to 16, it will trigger oPE07 [Analog Input Selection Error].
