Connecting an incremental encoder with Totem Pole outputs to the TSX CCY 1128

Pinout configuration of the module’s 15-pin SUB D connector

The pinout configuration of the module’s 15-pin SUB D connector, for connection to an incremental encoder with Totem Pole outputs, is as follows:

Pin No.	Signal	Designation
1	-	-
2	A-	Input to be connected to 0V encoder
3	B+ 24V	Encoder input, pulse B+ (10…30VDC)
4	-	-
5	Z-	Input to be connected to 0V encoder
6	-	-
7	10…30 V	Encoder supply output (+ 10…30VDC)
8	0 V	Encoder supply output (- 0VDC)
9	A+ 24V	Encoder input, pulse A+ (10…30VDC)
10	-	-
11	B-	Input to be connected to 0V encoder
12	Z+ 24V	Encoder input, zero latch pulse Z+ (10…30VDC)
13	EPSR	Positive encoder supply feedback input. Receives positive supply feedback from the encoder, which allows the module to verify the encoder’s presence.
14	-	-
15	5 V	Encoder supply output (+ 5VDC)

Diagram showing the A, B and Z encoder inputs of the module

The diagram below shows an A, B or Z encoder input used with an incremental encoder equipped with:

NOTE:

differential assembly is not possible, the negative polarity of each input (A-, B- and Z-), must be linked to the 0V encoder and the positive inputs (A+, B+ and Z+) to encoder outputs A+, B+ and Z+.
No line monitoring.

Recommendations

connect the positive encoder supply to pin 7 of the module’s 15-pin SUB D connector,
connect the module’s EPSR input to the positive supply if the encoder does not have a positive supply feedback output.
connect both terminals of the cable shielding to the protective ground.

CAUTION

ENCODER DAMAGE - PINOUT CONFIGURATION

Before connecting the encoder to the module, check the pinout configuration given by the encoder’s manufacturer.

Failure to follow these instructions can result in injury or equipment damage.
