Wiring Examples of Encoder Inputs
The following are wiring examples of an encoder with A, B, and Z-phase out-
puts.
Wiring Example 1: 12-VDC Open-collector Encoder
Wiring Example 2: 12-VDC
Voltage-output (Sink
Load) Encoder
In the following example, an input to the High-speed Counter Unit will be
turned OFF when an output from the encoder is H and an input to the Unit will
be turned ON when an output from the encoder is L.
