Parameter setting
SSI electronic module
Sliding direction Information for the orientation of encoder data. Generally, the SSI encoder
uses "MSB first".
Information on the sliding direction is provided on the encoder data sheet.
Click the input field to open the drop down menu.
• LSB first (lower-order bit is transmitted first)
• MSB first (most significant bit is transmitted first)
Edge clock signal Selection of the signal edge for clock inputs 4 and 8 at the SSI module.
Click the input field to open the drop down menu.
• Falling edge (1-0 edge)
• Rising edge (0-1 edge)
Coding Click the input field to open the drop down menu.
• Standard code
–The provided encoder value remains unchanged.
• Gray code
–The gray-coded value provided by the encoder is converted into a binary
value. The Gray code is another way of displaying the binary code. In the
Gray code, two adjacent Gray numbers differ by exactly one bit.
Therefore, transmission errors can easily be detected since adjacent
characters are allowed to differ by only one position.
SSI function After the module has been enabled, it starts clocking and evaluating the
encoder. Received data are saved to the input process image.
Click the input field to open the drop down menu.

• Enable
Current count value Display of the current count value
