5.7.6 Encoder interface unit, DSQC 354 (optional)
General The encoder interface unit handles communication with external conveyor:
• One encoder input (synchronisation of conveyor position with robot movements). The
encoder is supplied with 24 V and 0 V, and sends position information in two channels.
This information is computed by the on-board computer using quadrature decoding
(QDEC) to determine position and direction.
• One digital input (external start signal/conveyor synchronisation point)
