• Sine encoders with Endat capability add another approach to
communicating commutation position. Here, absolute position
information is stored in the encoder and is serially communicated to the
drive upon power up. The data is received synchronously by a clock
signal provided by the drive. Absolute position is known immediately;
therefore, an index signal is not needed.

CABLE LENGTHS
The recommended cable length when using the SERVOSTAR to source the
encoder is no longer than 50 ft. (15 m) Long encoder cables tend to have high
DC resistance that may create significant loading affects in the supply lines to
the encoder. Consider this carefully when designing the system. An option that
would allow the use of longer lengths would be to put a separate supply at the
motor to source the encoder. Except for noise susceptibility, signals returned to
the drive are differentially connected which normally do not constitute a
problem with longer cable lengths.
