(5) PID control
PID control is a control method in which derivative elements are added to PI control, thereby the temperature
shifts to a stable status in a short period of time even when a drastic change has occurred. By setting the
derivative time (D) properly, the control subject shifts to a stable status in a short period of time.
(a) Setting method
1.
Set "Method selection" to "Param write" of the control mode to be used.
"CC IE Field Configuration" windowSelect the temperature control module from "List of
stations"[CC IE Field Configuration][Online][Parameter Processing of Slave Station]
2.
The following table lists the setting details.
• "CH Proportion belt_P_setting_CH heating proportion belt": any value
• "CH Integration time_I_setting": any value
• "CH Differentiation time_D_setting": any value
