4. POSITIONING DEDICATED SIGNALS
The internal signals of the Motion CPU and the external signals to the Motion CPU are
used as positioning signals.
(1) Internal signals
The following five devices of the Motion CPU are used as the internal signals of
the Motion CPU.
• Internal relay (M) ........................... M2000 to M5487 (3488 points)
• Special relay (SM) ........................ SM0 to SM2255 (2256 points)
• Data register (D) ........................... D0 to D1599 (1600 points)
• Motion register (#) ......................... #8000 to #8751 (752 points)
• Special register (SD) .................... SD0 to SD2255 (2256 points)
(2) External signals
The external input signals to the Motion CPU are shown below.
• Upper/lower limit switch input .......... The upper/lower limit of the positioning
range is controlled.
• Stop signal ....................................... This signal makes the starting axis stop.
• Proximity dog signal ........................ ON/OFF signal from the proximity dog.
• Speed/position switching signal ...... Signal for switching from speed to position.
• Manual pulse generator input .......... Signal from the manual pulse generator.
