The program parameters of step 0 of CH0 control are described here. The parameters of steps 1 to 9 of CH0
and parameters of steps 0 to 9 of CH1 control are the same as those of step 0 of CH0 control. However, the
positions from the control register for each parameter differs. For details about the positions from the control
register for each program parameter, see 5-22 to 5-24.
(1) Control Register+180: Set Point (SP)
Configure the set point (SP) at the end of the step. Any value within the following range can be configured:
When input is thermocouple or resistance thermometer:
Set point (SP) lower limit ≤ Set point (SP) ≤ Set point (SP) upper limit
When input is voltage or current:
Linear conversion minimum value ≤ Set point (SP) ≤ Linear conversion maximum value
(2) Control Register+181: Step Time
The process time of each step can be configured as the step time.
When the set point (SP) is 500°C and the step time is 30 minutes, the PID module gradually increases the set
point (SP) to 500°C in 30 minutes. If the PV Start or PVR Start is selected as the program control mode start
type when the program control is started, the time is advanced until the set point (SP) becomes equal to the
process variable (PV). Then the program control starts and the set point is gradually increased to 500°C at the
end of the step. If the SP Start is selected as the program control mode start type
increased from the set point (SP) specified with "Set Point (SP) when Program Control Starts" to the set point
(SP) of step 0 in 30 minutes.
See page 6-41 and 6-42 for details about the program control mode start type.
