3 MAJOR POSITIONING CONTROL
3.1 Overview of the Major Positioning Controls
Continuous path control
■
Continuous path control
• The speed changes without the deceleration stop from the command speed of the positioning data No. currently being
executed to the speed of the next positioning data No. When the current speed is equal to the next speed, the speed does
not change.
• When the command speed is set to -1, the speed used in the previous positioning operation is used.
• The dwell time is ignored even if it is set.
• In the operation by the continuous path control (operation pattern: 11), the positioning of the next positioning No. is
automatically executed. Always set Operation pattern: 00 to the last positioning data to complete the positioning. If the
operation pattern is Positioning continue (01 or 11), the operation continues until Operation pattern: 00 is found. Therefore,
if Positioning complete (operation pattern: 00) is not set, the operation continues until the positioning data No. 600. If the
operation pattern of the positioning data No. 600 is not set to Positioning complete, the operation will be started again from
the positioning data No. 1.
• The speed switching is classified into two modes: the front-loading speed switching mode in which the speed is changed at
the end of the current positioning side and the standard speed switching mode in which the speed is changed at the start of
the next positioning side. (
