Process PID

1065 PID Cfg

PID Configuration

RW 16-bit

Integer

Main configuration of the Process PID controller.

Bit 0 “Preload Int” – Preload the PID integral term with PID Preload value.

Bit 1 “Ramp Ref” – Ramp PID Reference when first enabled.

Bit 2 “Zero Clamp” – Clamp PID output to zero when P1079 [PID Output Sel] is set to option 2 “Speed Trim” or 4 “Torque Trim.”

Bit 3 “Fdbk Sqrt” – Apply Square root function to the Feedback signal.

Bit 4 “Stop Mode” – When P1079 [PID Output Sel] is set to option 2 “Speed Trim,” PID remains active during stopping maneuver.

Bit 5 “Anti Windup” – Prevents PID integrator from getting too far ahead of frequency ramp.

Bit 6 “Percent Ref” – When P1079 [PID Output Sel] is set to option 2 “Speed Trim,” PID output is a percentage of the Speed Reference versus a percentage of P27

[Motor NP Hertz].

1066 PID Control

PID Control

RW 16-bit

Integer

Used for dynamically controlling the Process PID controller.

Bit 0 “PID Enable” – PID controller is enabled.

Bit 1 “PID Hold” – Hold PID integrator.

Bit 2 “PID Reset” – Reset PID integrator.

Bit 3 “PID InvError” – Invert PID error.
