Figure 3-18: Interface circuit of encoder input
If the encoder output is single-ended like PNP, NPN or OC( open collector), connect the signals to the EA+, EB+ ,
EZ+ and leave the EA-, EB-, EZ- unconnected.
Note: 1) High level input of EA+, EA-, EB+, EZ+ and EZ- should be greater than 3.5V and less than
5V. Low level input should be less than 0.5V. The encoder should offer 6mA current at the least for
each channel.
2) Don’t forget to connect the encoder ground to the controller’s ground.
