6.8.1 Description of function
 Action at Pattern end
Pattern end signal: A Pattern end signal may be created from OUT2, OUT3 or Digital output (DO) as an
Event output. Set the Pattern end output duration (P. 4-17, P. 4-26, P. 6-19).
When setting
“0:00” to the duration, output is continuously produced until the operation mode switches
to the Reset mode.
Control action selection:
PID control, Heat/Cool PID control or Position proportioning PID control (With FBR input):
Control continued or Control stop
Position proportioning PID control (When there is no FBR input or the FBR input is break):
 Control continued
 Open-side output OFF, Close-side output OFF
 Open-side output OFF, Close-side output ON
 Open-side output ON, Close-side output OFF
Event state: Action OFF or Action continued (selectable for each Event)
Transmission output state:
Action OFF or Action continued (selectable for each output)
Pattern end output at Pattern repeat or Pattern link:
OFF or ON (0.5 seconds)
It is not possible to invalidate the Pattern end output by setting the Pattern end output duration.
When Pattern end output is not required, do not assign Pattern end output at Output function
selection.
“Control stop” or “Control continued” can be set for Control action selection at Pattern end
(P. 4-41) of F50.07 in the Engineering mode when Output program value is assigned to OUT1.
Pattern end signal goes OFF when switching to the Fixed set point control mode (FIX), the Manual
control mode (MAN) or the Reset mode (RESET). Pattern end signal turns ON when returning to
the Program control mode (RUN).
To assign Pattern end output, refer to 6.2.1 Output assignment (OUT1 to OUT3)
and
6.2.2 Digital output (DO) assignment (DO1 to DO12) of the PF900/PF901 Instruction Manual
(IMR02L03-E) on the CD-ROM.
 Pattern end display
Alternately displays “ENd” and the remaining time of the Pattern end output duration when the operation is
in the Pattern end state. After the elapse of Pattern end output duration only “
ENd” flashes.
At the Dot display, the dots of the last segment of the Program pattern flash.
HOLD function is operative when the remaining time of the Pattern end output is displayed. When
the operation is in HOLD state, time counting of the remaining time is suspended but Pattern end
output remains ON. HOLD function is invalidated when the remaining time of the Pattern end
output is zero (0).
