Restrictions
• The start time adjustment function is valid only for Quick start.
• For [Pr.82] Start adjustment time, the setting at the analysis of the positioning data is valid.
• Turn on a start trigger after the analysis of the positioning data is completed. If a start trigger is turned on before the
analysis is completed, Pre-analysis incomplete start (Warning code: 09A2H) occurs and the RD75 starts outputting pulses
immediately after the analysis is completed.
If a positioning start trigger is turned on before the analysis of the positioning data is completed, the RD75
starts outputting pulses immediately after the analysis is completed and the variation in the start timing
becomes large.
Setting method
To use the start time adjustment function, write the following data into the RD75 using a program.
The set data is validated when the data is written into the RD75.
For details on the settings, refer to the following.

Precautions
Even if a single value is set in [Pr.82] Start adjustment time of multiple RD75s, the actual start adjustment times may differ due
to the characteristic of each RD75 module. If multiple RD75s start the positioning simultaneously or an RD75 is replaced,
adjust the value in [Pr.82] Start adjustment time again.
