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.
1067 PID Ref Sel
PID Reference Select
Selects the source for the PID Reference. Default:
Min/Max: 1070
1 / 159999 RW 32-bit
Integer
1068 PID Ref AnlgHi
PID Reference Analog High

–/+100.00 RW Real
1069 PID Ref AnlgLo
PID Reference Analog Low
When an analog input is selected for PID Ref this sets low value of scaling. Units:
Default:
Min/Max: %
0.00
–/+100.00 RW Real
1070 PID Setpoint
PID Setpoint
Provides an internal fixed value for PID Ref when P1067 [PID Ref Sel] is set to this
parameter. Units:
Default:
Min/Max: %
0.00
–/+100.00 RW Real
1071 PID Ref Mult
PID Reference Multiplier
Sets the multiplying factor which is applied to the Reference source before the
Reference is used. Units:
Default:
Min/Max: %
100.00
–/+100.00 RW Real
