■Restrictions
• The error "Continuous path control not possible" (error code: 1A1EH to 1A20H) will occur and the operation cannot start if
"continuous path control" is set in "[Da.1] Operation pattern". ("Continuous path control" cannot be set in fixed-feed control.)
• "Fixed-feed" cannot be set in "[Da.2] Control method" in the positioning data when "continuous path control" has been set in
"[Da.1] Operation pattern" of the immediately prior positioning data. (For example, if the operation pattern of positioning
data No. 1 is "continuous path control", fixed-feed control cannot be set in positioning data No. 2.) The error "Continuous
path control not possible" (error code: 1A1EH to 1A20H) will occur and the machine will carry out a deceleration stop if this
type of setting is carried out.
• In 2- or 3-axis fixed-feed control, if the movement amount of each axis exceeds "1073741824 (=2
speed" is set in "[Pr.20] Interpolation speed designation method", the error "Outside linear movement amount range" (error
code: 1A15H, 1A16H) occurs at a positioning start and the positioning cannot be started. (The maximum movement
amount that can be set in "[Da.6] Positioning address/movement amount" is "1073741824 (= 2
• In 4-axis fixed-feed control, set "1: Reference axis speed" in "[Pr.20] Interpolation speed designation method". If "0:
Composite speed" is set, the error "Interpolation mode error" (error code: 199AH) occurs and the positioning cannot be
started.
Setting positioning data
When using fixed-feed control (fixed-feed 1), set the following positioning data.
