Positioning Dedicated Signals - Mitsubishi Electric Q172CPU Programming Manual

4 POSITIONING DEDICATED SIGNALS

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
(2) External signals
Sensor, solenoid, etc.
(DI/O)
The following five devices of the Motion CPU are used as the internal signals of
the Motion CPU.
• Internal relay (M) .............................. M2000 to M5599 (3600 points)
• Special relay (SP.M) ........................ M9073 to M9079 (7 points)
• Data register (D) .............................. D0 to D1599 (1600 points)
• Motion register (#) ........................... #8000 to #8191 (192 points)
• Special register (SP.D) .................... D9180 to D9201 (22 points)
The external input signals to the Motion CPU are shown below.
• Upper/lower limit switch input.......... The upper/lower limit of the positioning
• Stop signal ....................................... Stop signal for speed control.
• 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.
