When the data is clocked into the CJ1W-MCH72, the position value is
interpreted. With this position value, it produces a value for MPOS and a
position error that is used to close the control loop.
The connections for SSI are:

The CJ1W-MCH72 encoder interface does not have a termination inside. In case of
long distances or disturbed communication, add an external termination to the inter-
face.
The table below and the figure give an example of how to connect the
Stegmann ATM 60-A encoder to the CJ1W-MCH72.
