Rockwell Automation 1336S Plus FRN 1.xx-5.xx - Manual (Page 126)

5–48 Programming
[PI Ref Select]
The source of the PI reference is selected with this
parameter. The value from the selected reference is
the “set point” for the Process PI regulator.
If using firmware version 4.01 and up, the drive is
capable of responding to a loss of the 4-20 mA
signal used as either a PI reference or PI feedback.
Response to loss of 4-20 mA signal is controlled by
programming and requires the following:
a) [Speed Control] must be set to “Process PI”
and
b) Either [PI Ref Select] or [PI Fdbk Select] must be
set to “4-20 mA.”
If both of the above conditions are met, the signal
loss response is controlled by the setting of [4-20
mA Loss Sel]. If this parameter is set to “Stop/Fault,”
loss of input will cause the drive to stop and issue a
Hertz Err Fault. Loss of input while any other setting
of [4-20 mA Loss Sel] is chosen will cause the drive
to activate the alarm bit (bit 6 of [Drive Status] and
bit 13 of [Drive Alarm]) and output programmed
[Minimum Freq].
No signal loss protection is offered for the 0-10V
input.
