After the axis hits the limit switches the visa read value from the motion conrtroller changes. The byte count is still equal to the return count but the value in my visa read changes only after hitting limit switch at a speed. For example: If the limit switch is set at a position of 300mm and if i give 300 mm there is not any trouble. But if i give a value of 340 mm, when my limit switch is set at 300 mm I have this problem. Kindly help.
