Operands:

S1: Target frequency for zero return

S2: JOG frequency for DOG

S3: input device for DOG

D:

Pulse output device

Explanations:

1.S1 (zero return speed): max. 100kHz. S2 (JOG speed for DOG) has to be lower than S1. JOG speed for DOG also refers to the start frequency.

2.S3 and D operands have to be used as an input/output set according to the table below, i.e. when S3 is specified as X4, D has to be specified as Y0; also when S3 is specified as X6, D has to be specified as Y2.

3.M1307 enables (ON) / disables (OFF) left limit switch of CH0 (Y0, Y1) and CH1 (Y2, Y3). M1307 has to be set up before the instruction executes. M1305 and M1306 can reverse the pulse output direction on Y1 and Y3 and have to be set up before instruction executes. Associated left limit switch for CH0 (Y0, Y1) is X5; associated left limit switch for CH1 (Y2, Y3) is X7. All functions, input points and output points are arranged as follows:

Channel	CH0(Y0,Y1)			CH1(Y2,Y3)		Remark
Input
DOG point	X4				X6
Left limit switch (M1307 = ON)	X5				X7
Reverse pulse output direction	M1305				M1306
Zero point selection	M1106				M1107	Please refer to point
						7 for the explanation.
M1346=On	Y4				Y5	Please refer to point
Start output clear signals						8 for the explanation.
	M1308		= Off			Please refer to point
D1312 != 0	(seeking Z-phase signal)
						9 for the explanation.
	X2				X3
D1312 != 0	M1308		= On			Please refer to
	(outputting the designated number of					point 10 for the
		pulses)				explanation.
