15. ABSOLUTE POSITION DETECTION SYSTEM

15.7.5 How to process the absolute position data at detection of stroke end

The servo amplifier stops the acceptance of the command pulse when stroke end (LSP

LSN) is detected,

clears the droop pulses to 0 at the same time, and stops the servo motor rapidly.

At this time, the programmable controller keeps outputting the command pulse. Since this causes a

discrepancy between the absolute position data of the servo amplifier and the programmable controller, a

difference will occur between the position data of the servo amplifier and that of the programmable

controller.

To prevent this difference in position data from occurring, do as described below. When the servo

amplifier has detected the stroke end, perform jog operation or the like to clear the stroke end. After that,

switch the servo-on (SON) off once, then on again, or switch the power off once, then on again. This causes

the absolute position data of the servo amplifier to be transferred to the programmable controller,

restoring the normal data.
