AXY:MC-Basic:group.POSITIONERROR
This property returns the position following error, which is the difference between the position commanded and the position feedback. The calculation accounts for the SERCOS delay, such that the position feedback is subtracted from the command issued three cycles previously. It is calculated every sample time and compared to maximum position error (PEMAX). If it exceeds the value of PEMAX, the group is brought to an immediate stop. If the group is at rest when the error is detected, the drives in the group are disabled. For a group, the position following error is calculated as the square root of the sum of the squares of each axis’ position error.
