I had an increment encoder (A+ A- B+ B- and Z+ Z-), for checking the encoder I use a PLC with High speed input counter (For example FP0-C16CT).
To calculate the encoder, I connect the encoder A and B to the high speed counter.
At plc programing, the step I did as following:
1) looking the signal for Z, which means when Z is detected the counter reset.
2) Looking the A coming first or B coming first to detect the CW or CCW.
3) Start counting and Sum up of A and B to get the resolution before detect the Z signal.
Did my concept right the encoder testing?
