White Paper: How to Connect HS35iQ Encoder Fault Output to a PLC

Software Setup

The routine written to read the fault output and turn on the LED is shown in Figure 2.

Figure 2. PLC software routine

An Examinine Off was used as the fault output is high during non-fault conditions and transitions to low when a

fault occurs. The routine simply reads the status of the fault output on DC IN 0 and will energize DC OUT 08

connected to the LED if a low condition is read.

Testing

After everything was connected properly, the program was downlaoded to the PLC and it was set to run mode.

To test proper functionality a cable fault was triggered by detaching the load resistor from one of the encoder

outputs (A/B/Z). The cable fault LED on the encoder transitions to

RED

at the same time the LED connected to

the PLC turns on (Figure 3). After the fault is corrected the cable fault LED on the encoder turns

GREEN

and

the LED on the PLC turns off (Figure 4).
