Chapter 5. FUNCTIONS

■PV start

If PV start is set in the program setup, PV is started by regular RUN operation.

The first point where PV matches the SP in the program pattern (including bias for both PV and SP) is searched for, and operation is started from that point.

However, note that if a matching point is not found, op- eration is started from the beginning of segment 1.

SP pattern

Current	Start point
PV value
(1)	A'
	A
Start point
	Start point
C

When PV has started, event operating points and the time of time events are automatically corrected. If the PV start function is selected by setup data C 5 2 to C 5 4 settings relating to external switch input, PV start can be executed without setting PV start in the program setup.

B

PV start is valid for segments in the currently selected program, and invalid for the segment at the pattern link destination.

PV start points

(1)PV starts at point A where the PV value first crosses the SP pattern.

(1)' PV starts at point B where the PV value first crosses the SP pattern.

(1)'' Point C of segment 1 is the PV start point since there is no point where the PV value crosses the SP value.

■Cycle

The cycle function is for repeating operation from the No.1 segment of the program pattern to the final set segment for a preset number of cycles. The number of cycles can be set up to 9999.

When a number of cycles “n” is set, the operation count becomes “n+1”.

When executing cycle operation, operation at the end point of the final segment is not carried out, and operation is restarted with the settings of events 1 to 3 and time events 1 to 5 cleared. At this time, PV is not started and opera- tion starts from the No.1 segment even if PV start is set.

If the SPs at the pattern start and end points do not match, the SP changes in a stepped manner during cycle opera- tion.
