ZON Zone PID selection STD
0: Segment PID selection
1: Zone PID selection (selection by
PV)
2: Zone PID selection (selection by
target SP)
4: Zone PID selection (selection by
SP)
5: Local PID selection
* If set to “Segment PID
selection,” allows PID constants
to be selected for each
segments.
* If set to “Zone PID selection,”
automatically selects PID
constants according to the
range set in the Reference
point.
* If set to “Local PID selection,”
local PID is selected irrespective
of the operation modes.

In Cascade control, the following parameters are also displayed for secondary loop. (the LP2 lamp
is lit)
• Parameter: CNT, ALG, ALNO.
The parameter CNT of Loop 2 displays PID and H/C.
