Delta DVP-ES2/EX2/SS2/SA2/SX2/SE manual Points to note, Device Function Setup Range Explanation

3. Instruction Set

Points to note:

1.There is no limitation on the times of using this instruction. However, the register No. designated in S3~ S3+19 cannot be repeated.

2.For 16-bit instruction, S3 occupies 20 registers. In the program example above, the area designated in S3 is D100 ~ D119.

3.Before the execution of PID instruction, users have to transmit the parameters to the designated register area by MOV instruction. If the designated registers are latched, use MOVP instruction to transmit all parameters only once

4.Settings of S3 in the 16-bit instruction:

Device	Function	Setup Range	Explanation
No.
			Time interval between PID
			calculations and updates of MV. If TS
			= 0, PID instruction will not be
S3:	Sampling time (TS)	1~2,000	enabled. If TS is less than 1 program
		(unit: 10ms)	scan time, PID instruction sets S3 as 1
			program scan time, i.e. the minimum
			TS has to be longer than the program
			scan time.
	Propotional gain		The proportion for
S3+1:		0~30,000(%)	magnifying/minifying the error
	(KP)
			between SV and PV.
			The proportion for
	Integral gain (KI)	0~30,000(%)	magnifying/minifying the integral
			value (The accumulated error). For
S3+2:
			control mode K0~K5.
	Integral time	0~30,000 (ms)	For control mode K10
	constant (TI)
			The proportion for
		-30,000~30,000	magnifying/minifying the derivative
	Derivative gain (KD)		value (The rate of change of the
		(%)
S3+3:			process error). For control mode
			K0~K5
	Derivative time	-30,000~30,000	For control mode K10
	constant (TD)	(ms)
S3+4:	Control mode	0: Automatic control
		1: Forward control (E = SV - PV).
