Sequence error
  1. Switch OFF DI ABSQ until DO ABSR is OFF.
  2. Switch ON ABSQ until DO ABSR is ON.
Correct the reading sequence of I/O.
Reading time out Check if the time between switching ON DO ABSR and switching ON ABSQ exceeds
200 ms.
After switching ON DO ABSR (the absolute position data is ready), read DO ABSD and switch ON DI ABSQ within 200 ms so as to
inform the servo drive data reading is completed.
