6.5 SSI Absolute Encoder Port
6.5.1 Function of SSI Absolute Encoder
The
motion controller
’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.
