Detailed Wiring Information 05/2008 Danaher Motion
56 S200-CNS Product Manual
10.15 ENCODER MOTOR FEEDBACK
The following diagrams indicate how to wire an encoder feedback to the S200 Position Node drive.
The information provided pertains to Danaher Motion AKM Series motors. Other motors or encoder
manufacturers may use different conventions when naming signals. Danaher Motion can not be
responsible for the differences but a phasing diagram and some explanations are provided to help
the user determine the proper wiring and setup for other component suppliers.
The AKM motor wiring is provided below in both schematic and tabular form.

A+ 12 3 BLU 3 A Data Channel Input
A- 13 4 BLU/BLK 4 A Channel complement (Differential driver)
B+ 14 1 GRN 1 B Data Channel Input
B- 15 2 GRN/BLK 2 B Channel complement (Differential driver)
Case Case - Shell 18 Cable shield connections. Normally connects
the back shell on both ends of the cables.
(Molex does not have a back shell so pin 18 is
used).
Motors using incremental encoders used with the S200 Position Node must provide hall emulation
commutation tracks in with open collector drive circuits. The alignment of the commutation tracks to
the motor’s back EMF (magnetic alignment) is critical. The following phase diagram will indicate the
proper alignment. S200 OC Tools and the S200 PN support a phase offset adjustment when the hall
tracks cannot be properly aligned but the actual determination of the correct offset is by trial and
error. The basic procedure is not discussed other than to say that the phase is correct when the
motor’s actual output torque is balanced in both directions for a given command.
