Program-related Functions

■ SP Start
Operation starts as programmed from the SP of segment 0. However, if the
Reset Operation parameter is set to fixed SP operation, program operation
will start with the fixed SP or remote SP.
■ Slope-priority PV Start
Program operation starts at the first SP that matches the PV from the start of
operation. If the PV does not match any SP in the program, operation starts at
the beginning of the program.
The following figure shows an example of the operation. The first position
where the PV and the SP match is in segment 3. From there, the program is
indicated by a bold line. The program prior to that position is ignored.
Set point
Segment 0
PV at startup
If segment 0 is a step segment in the gradient setting, the program pattern will
be set from the SP at program startup to the step segment SP of segment 0.
Therefore, if the PV at startup is between the SP (FSP or RSP) at program
startup and the SP in the step segment, the program will start from the step
segment SP of segment 0.
• When a standby operation is set, the program does not start operating
until the standby time (stb) (set in h.min or days.h) has elapsed after the
Run/Reset parameter is set to Run.
• The following conditions apply to operation during standby status:
• The indicators and status displays will show run status.
• If the Reset Operation parameter is set to stop control, the MV at reset
will be output from the control output. If the Reset Operation parameter
is set to fixed SP operation, the fixed SP or remote SP will be output.
• Hold, advance, and auto-tuning operations cannot be used if the Reset
Operation parameter is set to stop control. If auto-tuning is executed
when the Reset Operation parameter is set to fixed SP operation, the
remaining standby time during auto-tuning execution will be held.
• If the power is interrupted during standby status, the remaining stand-
by time is held (if the Startup Operation parameter is set to Continue
or Manual and the program was running and with manual operation
before the power was interrupted).
