• During pre-analysis mode, do not turn OFF→ON "[Cd.184] Positioning start signal" when "[Pr.42] External command
function selection" is set to "0: Start external positioning" and "[Cd.8] Enable external commands" is set to "1: Enable
external commands". Positioning start signal input at quick external start (Warning code: 09A7H) occurs and no operation is
started.
• When [Pr.42] External command function selection is set to a value other than 0: Start with external command in the pre-
analysis mode, an external command signal is disabled for 1.77 ms maximum after start starting. Input an external
command signal 1.77 ms or longer after starting.
■Precautions for the processing performed at the pre-analysis of positioning data
The following table lists the processing performed at the pre-analysis of positioning data.
Major positioning control
Position control 1-axis linear control
2-axis linear interpolation control
1-axis fixed-feed control
2-axis fixed-feed control
2-axis circular interpolation
control
1-axis speed control
2-axis speed control

Position-speed switching control
Current value change
Note that if [Cd.43] Analysis mode setting is set to 1: Pre-analysis mode and is held, the analysis of the next positioning data
will start immediately after the current positioning operation is completed.
For example, Positioning complete signal ([Md.31] Status: b15) turns on at the completion of positioning and immediately
turns OFF when the pre-analysis is started at the completion of positioning. Consequently, depending on the scan time, the
ON state of the signal may not be detected by the program used. If necessary, set 0 in [Cd.3] Positioning start No. after the
positioning starts to avoid the analysis of the next positioning data.
Program example
For the program example of the quick start, refer to the following.

• Clearing the axis control data
• Initializing the axis monitor data
• Positioning complete signal ([Md.31] Status: b15) OFF
• Clearing the axis control data
• Initializing the axis monitor data
• Positioning complete signal ([Md.31] Status: b15) OFF
• Clearing the current feed value to 0

When [Pr.21] Current feed value during speed control is 2: Clear current feed value to 0, the
following processing is also performed.
• Clearing the current feed value to 0
• Clearing the values after the decimal point held in the positioning module
• Clearing the axis control data
• Initializing the axis monitor data
• Positioning complete signal ([Md.31] Status: b15) OFF
When [Pr.21] Current feed value during speed control is 2: Clear current feed value to 0, the
following processing is also performed.
• Clearing the current feed value to 0
• Clearing the values after the decimal point held in the positioning module
• Clearing the axis control data
• Initializing the axis monitor data
• Positioning complete signal ([Md.31] Status: b15) OFF
• Clearing the current feed value to 0
• Clearing the values after the decimal point held in the positioning module
