Precautions for Correct Use
If the reset operation is fixed SP control, rate of rise programming is set, and segment 0 is a step
segment, the program pattern includes everything from the fixed SP (the SP for starting program
operation) to the SP for segment 0 (step segment).
Therefore, a PV start is not performed if the PV at the start of operation is between the fixed SP
and the SP for the segment 0 step segment, as shown in the following diagram. Program opera-
tion will start from the SP of the segment 0 step segment.
Additional Information
• For the PV start operation, operation starts from the first point in the middle of the program
when the SP and PV are equal. If you want to start from the PV when starting segment 0, do
not use the PV start operation. Rather, set the program setting method to rate of rise program-
ming and set the reset operation to stop control.
• If program repetitions or program links are set, the PV Start operates only for the first program
execution.
z Related Parameters
You can delay the start of program operation.
• If the standby operation is set, the program does not start until the time set for the Standby Time
parameter (stb) (hours and minutes, or days and hours) has elapsed after changing from reset
status to run status.
• 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 will be
output.
• Hold, advance, and autotuning operations cannot be used if the Reset Operation parameter is set
to stop control.
If autotuning is executed when the Reset Operation parameter is set to fixed SP operation, the
remaining standby time during autotuning execution will be retained.
