4 AUXILIARY AND APPLIED FUNCTIONS
Since the system-specific delay exists in the current value data of the
synchronous encoder axis, there may be a difference between the
actual current value and the current value of mark detection.
When the "synchronous encoder current value", "synchronous encoder
axis current value" or "synchronous encoder axis current value per
cycle" is used in the mark detection data, the mark detection signal
compensation time shown below can be set to compensate the delay.
However, when the "phase compensation advance time" is set in the
synchronous control parameter to compensate the delay of the
synchronous encoder, setting of the mark detection signal compensation
time is not necessary.
