Connecting an Incremental Encoder

Connection Diagram
The type of interface is either RS 422 / RS 485 or totem pole:
(*) standard pinouts for an encoder equipped with a 12-pin DIN connector.
Each signal (A+, A- for example) should be connected by a twisted pair. To reduce on-line voltage falls, it is recommended to connect each supply point using a pair. Cable shielding should be connected at each end to the protective ground.
CAUTION
IMPROPER POWER SUPPLY
Connect the +supply encoder input of the DIN connector to a 10-30 V supply wire or a 5 V wire, according to the type of encoder used.
Failure to follow these instructions can result in injury or equipment damage.
