4.1.3 SSI interface
The SSI (Synchronous Serial Interface) is specifically designed for use with Baldor SSI motors,
which incorporate a custom Baumer SSI encoder. Correct operation with other SSI interfaces
cannot be guaranteed. The SSI interface connections are made using the 15-pin D-type female
connector X8. Twisted pair cables must be used for the complementary signal pairs e.g. Data+
and Data-. The overall cable shield (screen) must be connected to the metallic shell of the D-type
connector. Connector X8 includes a ‘Sense’ pin, which is used to detect the voltage drop on long
cable runs. This allows the MotiFlex
e
100 to increase the supply voltage on pin 12 to maintain a
5 VDC supply at the encoder (200 mA max).
