EXT-IN Connector
The EXT-IN (external input) connector is used for wiring external inputs.
Since the C500-NC222-E Position Control Unit allows dual axis control, the
EXT-IN connector provides inputs for both X and Y axes for connecting in-
puts from limit switches, from switches to stop the system, and from the me-
chanical origin. The connector type and pin layouts are shown below.

Unused
Ground (0 V) terminal for external 24-VDC power supply
Limit switch input for Y axis in CCW direction (NC)
Used for stopping Y axis earlier than normal decelera-
tion-stop (NO). Active at its leading edge.
Used as Y-axis mechanical origin (NO).
Used to stop Y axis in an emergency such as a run-away
motor (NC).
Limit switch input for Y axis in CW direction (NC)
