Quick start

Positioning controls can be started quickly by analyzing in advance the positioning data executed immediately after the
current operation to prevent the analysis time affecting the start. Positioning data for the major positioning controls can be
started in this mode.
By using an external command signal as a start trigger, positioning controls can be started bypassing the
program, which means that the operation is quickly started without being affected by the execution time of the
program.
Starting method
After setting positioning data, set "[Cd.43] Analysis mode setting" to "1: Pre-analysis mode" and input a start trigger signal
while "[Md.61] Analysis complete flag" is "1: Analysis completed". The following table shows the quick start triggers used in
this mode.
Start trigger name Starting method (Start trigger)
Positioning start signal Turning OFF→ON the "[Cd.184] Positioning start
signal"
External command signal Turning OFF→ON external command signals (CHG)
Depending on the start timing of the positioning data analysis, a start trigger used is determined. Even if the settings are
changed after the start of the positioning data analysis, the changed settings are not valid. Consequently, when the following
settings are configured, external command signals (CHG) are used as a start trigger.
• Set "[Pr.42] External command function selection" to "0: Start with external command"
• Set "[Cd.8] Enable external commands" to "1: Enable external commands"
If not set as described above, the "[Cd.184] Positioning start signal" can be used as a start trigger.
Positioning data to be started
Starts the positioning data specified in [Cd.3] Positioning start No.
Starts the positioning data specified in [Cd.3] Positioning start No.
