Parameter
I/O signals and parameter setting
Turn on the X14 signal to perform PID control. When this signal is off, PID action is not performed
and normal inverter operation is performed. (Note that the X14 signal need not be turned on for
PID control via LONWORKS communication.)
Enter the set point across inverter terminals 2-5 or into Pr. 133 and enter the measured value
signal across inverter terminals 4-5. At this time, set "20" or "21" in Pr. 128.
When entering the calculated deviation signal of an external (PID) controller , enter it across ter-
minals 1-5. At this time, set "10" or "11" in Pr. 128.

Description
Turn on X14 to perform PID
control.
By turning on X64, forward action
can be selected for PID reverse
action (Pr. 128 = 10, 20), and
reverse action for forward action
(Pr. 128 = 11, 21).
Enter the set point for PID control. Pr. 128 = 20, 21; Pr. 133 = 9999

Set the set value (Pr. 133) from
the operation panel or parameter
unit.

lated externally.
