Sometimes encoders require different supply voltages than 5 V or need more than the 200 mA provided by the
drive. In those cases, the connection from the external power source should be as shown next:
9.6.5. Feedback wiring recommendations
Signal distortion and electrical noise is a common problem in feedback signals. These problems can result in a bad
position or velocity calculation for both digital feedbacks (gain or loss of counts) and analog feedbacks (wrong
voltage levels).To minimize these problems some wiring recommendations are shown:
Use differential signals
whenever is possible. That is, connect both positive and negative signals of
differential feedback sensors.
Use a twisted pair for each differential group of signals
and another
twisted pair for the +5 V supply and GND. Twisted-pairs help in the elimination of noise because
disturbances induced in twisted pairs
Twisted-pairs help in elimination of noise due to electromagnetic fields by twisting the two signal leads at
regular intervals. Any induced disturbance in the wire will have the same magnitude and result in error
cancellation.
