Operands:
S 1 : Target frequency for zero return S 2 : JOG frequency for DOG S 3 : input device for DOG D:
Pulse output device
Explanations:
1. S 1 (zero return speed): max. 100kHz. S 2 (JOG speed for DOG) has to be lower than S 1. JOG
speed for DOG also refers to the start frequency.
2. S 3 and D operands have to be used as an input/output set according to the table below, i.e. when
S 3 is specified as X4, D has to be specified as Y0; also when S 3 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
