About Position Capture: The master encoder position can be captured only by the Master Trigger input
(input #5), and only when that input is defined as a "trigger interrupt" input with the
(see
command). When the "trigger interrupt" input is activated (active edge), the master encoder

position is captured and the position is available through the use of the

Position Capture Accuracy: The master encoder position capture accuracy is ±1 encoder count.
