PD control
PD control is a control method in which the derivative time (D) is set in addition to P control. The control mechanism is the
same as P control.
■Setting method (in the R mode)
Set each item as follows:
• 'CH1 Proportional band (P) setting' (Un\G431): Any value (Page 245 CH1 Proportional band (P) setting)
• 'CH1 Heating proportional band (Ph) setting' (Un\G431): Any value (Page 247 CH1 Heating proportional band (Ph)
setting)
• 'CH1 Integral time (I) setting' (Un\G432): 0 (0s) (Page 247 CH1 Integral time (I) setting)
• 'CH1 Derivative time (D) setting' (Un\G433): Any value (Page 248 CH1 Derivative time (D) setting)
■Setting method (in the Q compatible mode)
Set each item as follows:
• "Proportion Belt (P) Setting": Any value
• "Integration Time (I) Setting": 0s
• "Differentiation Time (D) Setting": Any value

PID control
PID control is a control method in which derivative elements are added to PI control, and 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 controlled object shifts to a stable status in a short period of time.
