A151 [PID Trim Lo]
Sets the minimum positive value that is added to a PID reference when PID trim is used.
Values Default: 0.0 Hz
Min/Max: 0.0/320.0 Hz
Display: 0.1 Hz
A152 [PID Ref Sel] Related Parameter(s): P038 , T070 , T071 , T072 , T074 , T075
Stop drive before changing this parameter.
Enables/disables PID mode and selects the source of the PID reference. Refer to Appendix D for details.
Note: PID analog reference is scaled through the [Analog In x Hi/Lo] parameters. The invert operation is obtained through programming these two parameters. If A152 [PID Ref Sel]
is not set to zero, PID can be disabled by programming a digital input.
Options 0 “PID Disabled” (Default)
1 “PID Setpoint
2 “Analog In 1”
3 “Analog In 2”
4 “Comm Port”
5 “Setpnt, Trim” Use PID output as Trim on [Frequency Select]
6 “A-In 1, Trim” Use PID output as Trim on [Frequency Select]
7 “A-In 2, Trim”
(1)
Use PID output as Trim on [Frequency Select]
8 “Comm, Trim” Use PID output as Trim on [Frequency Select]
(1) The PID will not function with bipolar input. It will ignore any negative voltages and treat them like zero.
A153 [PID Feedback Sel] Related Parameter(s): T070 , T071 , T072 , T074 , T075 , A204 , A205
Select the source of the PID feedback. Refer to Appendix D for details.
Note: PID analog reference is scaled through the [Analog In x Hi/Lo] parameters. The invert operation is obtained through programming these two parameters.
Options 0 “Analog In 1” (Default)
1 “Analog In 2”
2 “Comm Port”
(1)
3 “ACT1 - ACT2”
(with FRN 7.xx and later)
ACT1 minus ACT2
4 “ACT1 + ACT2”
(with FRN 7.xx and later)
ACT1 plus ACT2
5 “ACT1 * ACT2”
(with FRN 7.xx and later)
ACT1 multiplied by ACT2
6 “ACT1 / ACT2”
(with FRN 7.xx and later)
ACT1 divided by ACT2
7 “Min A1, A2”
(with FRN 7.xx and later)
The smaller of ACT1 or ACT2 is used as the feedback signal.
8 “Max A1, A2”
(with FRN 7.xx and later)
The larger of ACT1 or ACT2 is used as the feedback signal.
(1) The PID will not function with bipolar input. It will ignore any negative voltages and treat them like zero.
A154 [PID Prop Gain]
Sets the value for the PID proportional component when the PID mode is enabled by A152 [PID Ref Sel].
Values Default: 1.00
Min/Max: 0.00/99.99
Display: 0.01
