Precautions during control
• 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 if the movement direction changes. (See below) For this reason, the output will rapidly reverse when the reference
axis movement direction changes. To prevent the rapid output reversal, assign not the continuous path control "11", but the
continuous positioning control "01" to the positioning data of the passing point.
