Setting Encoder Input Terminal (TBEN1, TBEN2)

The controller provides two TBEN terminals that allow the input of external encoders. They support A, B and Z phases as inputs, and perform counts based on 12Vdc. In addition, S phase can be used as the conveyor’s Start sensor.

• To ensure maximum input accuracy, observe the following: Use shielded, twisted pair cables to reduce noise.
• Connect the cable shield to the ground terminal inside the controller.
• In the case of S phase inputs, connect a pull-up or pull-down resistance according to the sensor type(NPN/PNP) to prevent floating.

The figure below shows a sample encoder and sensor configuration, so refer to it while establishing connections.
