LE RCS-S. (SERCOS PROTOCOL)
The optical power value depends on the total length of the cable being used. Assigning other
optical power values, e.g. a value of 6 for a length of 3 m, can cause communication errors
due to fiber optic signal distortion.
Display ·D40·. Status and error display.
7-segment display for module status and error codes.
Connectors ·E21A· ·E21B· ·E21C· ·E21D·. Feedback inputs (1 per connector).
4 15-pin female SUB-D HD type connectors. The feedback signals may be incremental (TTL,
differential TTL, Vpp) or communication protocols (SSI).
• If the input is configured as TTL, differential TTL or Vpp, it will provide over-current
feedback alarm (300 mA).
• If the input is configured as differential TTL, it will provide cable-breakage detection
alarm.
• Feedback signals (TTL, differential TTL, Vpp).
