			If the proportional band is narrow (parameter setting is small), the
			manipulated variable varies greatly with a slight change of the process value.
129	0.1 to 1000%	PID proportional	Hence, as the proportional band narrows, the response sensitivity (gain)
		band	improves but the stability deteriorates, e.g. hunting occurs.
			Gain K = 1/proportional band.
	9999		No proportional control
			Time only required for the integral (I) action to provide the same manipulated
130	0.1 to 3600 s	PID integral time	variable as that for the proportional (P) action. As the integral time
			decreases, the set point is reached earlier but hunting occurs more easily.
	9999		No integral control.
	0 to 100%		Set the upper limit. If the feedback value exceeds the setting, the FUP signal
131		Upper limit	is output. (Process value of 4mA is equivalent to 0% and 20mA to 100%.)
	9999			No function
			Set the lower limit. If the feedback value falls below the setting, the FDN
132	0 to 100%	Lower limit	signal is output. (Process value of 4mA is equivalent to 0% and 20mA to
			100%.)
	9999			No function
		PID action set	Only valid for the PU command in the PU operation or PU/external combined
			mode.
133	0 to 100%	point for PU
			For external operation, the voltage across 2-5 is the set point.
		operation
			(Pr. 902 value is equivalent to 0% and Pr. 903 value to 100%.)
			Time only required for the differential (D) action to provide the same process
134	0.01 to 10.00 s	PID differential	value as that for the proportional (P) action. As the differential time
		time	increases, greater response is made to the deviation change.
	9999		No differential control.

(6) Adjustment procedure

Parameter setting

Terminal setting

Adjust the PID control parameters, Pr. 128 to Pr. 134

Set the I/O terminals for PID control. (Pr. 180 to Pr. 186, Pr. 190 to Pr.195) Pr. 128 = 10, 11, 20, 21

Switch X14 signal on.
