Installation of Photoelectric Absolute Rotary Encoder
The following chapter describes all aspects helpful for installation of photoelectric absolute
rotary encoders with bus cover. Depending on the rotary encoder model there are the following
connection variants:
Rotary encoder with bus cover equipped with cable glands
■
Rotary encoder with bus cover equipped with a cable exit
■
Rotary encoder with bus cover equipped with one or two M12x1 connectors, 5-pin
■
Bus cover features like node number adressing, baud rate setting and activation of termination
resistor are identical for all these variants.

Signal Assignment of Terminal Block
The rotary encoder is connected with two or three cables depending on whether the power
supply is integrated into the bus cable or connected separately. If the power supply is
integrated into the bus cable, one of the cable glands can be fitted with a plug. The cable
glands are suitable for cable diameters from 6.5 up to 9 mm.
