(2) Control precautions
• If the movement amount designated by the positioning data is small when the continuous path control is
executed, the output speed may not reach the designated speed.
• The movement direction is not checked during interpolation operation. Therefore, a deceleration stops are
not carried out even the movement direction changes. For this reason, the output will suddenly reverse when
the reference axis movement direction changes. To prevent the sudden output reversal, assign not the
continuous path control "11", but the continuous positioning control "01" to the positioning data of the passing
point.
