A152 [PID Ref Sel]
Related Parameter(s):
Stop drive before changing this parameter.
Enables/disables PID mode and selects the source of the PID reference. Refer to
for
details.
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]

The PID will not function with bipolar input. It will ignore any negative voltages and treat them like
zero.
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.
A153 [PID Feedback Sel]
Related Parameter(s):
Select the source of the PID feedback. Refer to
for details.
Options
0 “Analog In 1” (Default)
The PID will not function with a bipolar input. Negative
voltages are treated as 0 volts.
1 “Analog In 2”
(1)
2 “Comm Port”
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.
