Tech Tip

The pulse amplitude of the encoder’s output square wave signal is dependent on the voltage you supply the sensor. For example, if you provide 5V to Sensor Voltage +, then Channels A & B will have a pulse amplitude of 5V.

To enhance the resolution, the encoder is attached to the motor before the gearbox.

Gear train damage can occur if stalled (locked).
