Absolute Rotary Encoder
Installation of Photoelectric Absolute Rotary Encoder
Bus Connection
The bus cover fulfills the function of a T-coupler. From there the wiring must be done according
to figure you find before. Please note the assignment of incoming and outgoing bus signals.
Caution!
Activated bus termination separates "Bus in" and "Bus out"
Non-observance of separation of "Bus in" and "Bus out" causes interferences on the CANopen
bus.
If you activate the bus termination on the rotary encoder ensure that the rotary encoder is the
last CANopen bus participant in the bus line.
