b5-71: Min PID Transducer Scaling
No.
(Hex.)
Name
Description
Default
(Range)
b5-71
(3C22)
Min PID Transducer Scaling
Sets the minimum PID level corresponding to the lowest analog input signal level.
0.00
(-99.99 - +99.99)
Note:
•
To enable this parameter, you must set
b5-71
<
b5-38 [PID User Unit Display Scaling]
. If you set
b5-71
>
b5-38
, the drive will disable all
PID analog inputs.
•
Parameters
b5-46 [PID Unit Display Selection]
,
b5-38
, and
b5-39 [PID User Unit Display Digits]
set the unit, range, and resolution.
When you set
b5-71 < 0
, the drive appropriately scales the setpoint and feedback values of the drive, but internally
limits to 0 when the reported value from the transducer is negative.
shows an example of the transducer scaling lower limit when:
•
b5-01 = 1 [PID Mode Setting = Standard]
•
b5-46 = 3 [°F: Fahrenheit]
•
b5-71 < 0.00
•
H3-09 = 0 [Terminal A2 Signal Level Select = 0-10V (LowLim=0)]
•
H3-10 = B [Terminal A2 Function Selection = PID Feedback]
