Example of the multiplexing of encoders with a 5 V supply.

General

Illustration:

IMPORTANT

When carrying out multiplexing, encoders with parallel outputs of the same type must be used:

with the same number of data bits,
and the same supply (the encoders have a supply of either 10…30 VDC, or 5 VDC).

NOTE: if the control supply encoder is not used, the +EPSR terminal (encoder + supply feedback) must be connected to +10…30 V or +5 Vand the –EPSR terminal (encoder supply feedback) must be connected to 0 V.

(1) Using the Q0 and Q1 reflex outputs from TSX CTY 2C is not compulsory for addressing encoders; as this operation can be carried out by 2 outputs from a discrete module. In this case, the shared outputs at the COM input of the TELEFAST ABE-7CPA11 must be connected.

(2) It is compulsory to set the configuration micro-switch according to the number of encoders connected on the base (OFF if 1 encoder, or ON if 2 encoders).
