4-7 Setting Programs
You program operation so that the SP changes with time. The broken-line pattern that represents the
changes in the SP over time is called a program. The programs are set in advance by the user. The
main features are as follows:
• You can create up to eight programs (i.e., patterns).
• You can set up to 32 segments (i.e., straight lines) for each program.
• There are three segment formats: ramp (sloped), soak (horizontal), and step (vertical).
• Program operation starts when you change the Run/Reset parameter to Run. Details on the
Run/Reset parameter are described in the next section.
“Run” indicates that program operation is in progress. “Reset” indicates that the program is stopped.
You can use the Reset Operation parameter to specify whether fixed SP operation is to be performed or
control is to be stopped all together while the program is stopped. For details, refer to Selecting the
Reset Operation, below.
The run/reset status changes at the following times. The default is rst (reset).
• When the M (Mode) and D Keys are pressed simultaneously for at least 1 s
• When the r-r parameter (Run/Reset) in the Operation Level is changed to run
• When the run/reset status is changed with the S (PF) Key
• When the run/reset status is changed with an event input
Additional Information
You can set the Standby Time parameter to delay the start of program operation after changing
from reset to run status. For details, refer to 5-15-13 Standby Operation.
