Delta DVP-ES2/EX2/SS2/SA2/SX2/SE manual ⋅10 3 rpm n, SA2/SE/SX2

DVP-ES2/EX2/SS2/SA2/SX2/SE Operation Manual - Programming

	SA2/SE/SX2:	5KHz.
Max frequency	100kHz		10KHz
		X1(X0/X1) of SA2/SE: 30kHz
	SS2: 20kHz

14.D occupies 5 consecutive registers, D + 1 and D store the results of previous pulse detection; D +3 and D + 2 store the current accumulated number of pulses; D + 4 store the current time remaining (max. 32,767ms).

15.If X0, X1, X2, X6 or X7 are used in a SPD instruction, their associated high-speed counters or external interrupts I000/I001, I100/I101, I200/I201, I600/I601 or I700/I701 can not be used.

16.For ES2/EX2 before V0.92: when X0, X2, X6 and X7 are used, they will be detected as 1-phase input. When X1 is used, X0(A) and X1(B) will be applied together as AB-phase input.

17.For SS2/SA2/SX2/SE and ES2/EX2 V1.00 or later: when X0, X2, X4 and X6 are used, they will be detected as 1-phase input. When X1, X3, x5, X7 are used, X0, X2, X4, X6 will be applied together as AB-phase input.

18.This instruction is mainly used to obtain the value of rotation speed and the results in D are in

proportion to the rotation speed. Rotation speed N can be calculated by the following equation

	60(D0)	N:	Rotation speed
N=		⋅103 (rpm) n:	The number of pulses produced per rotation
	nt
		t:	Detecting time specified by S2 (ms)

Program Example:

19.When X7 = ON, D2 stores the high-speed pulses at X0 for 1,000ms and stops automatically. The results are stored in D0, D1.

20.When the 1000ms of counting is completed, D2 will be reset. When X7 turns ON again, D2 starts counting again.
