6.5 SSI Absolute Encoder Port
6.5.1 Function of SSI Absolute Encoder
DVP15MC11T’s COM/SSI port is a 15-pin D-SUB interface which can be used to connect SSI encoder. In
addition, the port also includes the 5V (400mA) power output which provides the power supply to the encoder.
Users can create an SSI encoder axis to control the motion of slave axes according to the number of pulses
received via the encoder port.
