10.2.2. Terminating resistor

If the connected encoder is the last one in the bus line, the bus must be terminated with a resistor.

The resistors are integrated in the bus cover and are connected using a two-pole DIP switch.



The internal terminating resistors must be set to "ON" in the last user with the two-pole DIP switch

(default setting OFF).

both ON = Final user

both OFF = user X

10.2.3. Bus cover connection



Release the cap nut of the cable gland.



Push the cap nut and seal insert with contact sleeve onto the cable sheath.



Strip the cable sheath and cores, shorten the shield film where this exists (see Fig.)



Bend over the braided screen by approx. 90°.



Push the sealing insert with contact sleeve along as far as the braided shield. Insert the sealing insert

with contact sleeve and cable flush into the cable gland and tighten the cap nut.

For standard encoder

For G0AMH, G0MMH, GBAMH and GBMMH

Bus cable



Terminals with the same designation are internally interconnected.



For the power supply, use only cable gland 3. For the bus lines, cable gland 1 or 2 can be optionally

selected. For the bus lines, cable glands 1 or 2 can be freely selected. Observe the admissible cable

cross sections.



Insert the cores using the shortest route from the cable gland to the terminal strip. Observe the admissible

core cross-section. Use isolated core end sleeves.



Avoid crossing over data lines with the supply voltage line.
