Precautions during control
• After positioning data analysis, the system is put in an execution prohibition flag OFF waiting status. Any change made to
the positioning data in the execution prohibition flag OFF waiting status is not reflected on the positioning data. Change the
positioning data before turning ON the positioning start signal.
• The pre-reading start function is invalid if the execution prohibition flag is turned OFF between when the positioning start
signal has turned ON and when positioning data analysis is completed (Ta < start time, Ta: Reference to the above figure).
• The data No. which can execute positioning start using "[Cd.3] Positioning start No." with the pre-reading start function are
No.1 to 600 only. Performing the pre-reading start function at the setting of No.7000 to 7004 or 9001 to 9004 will result in
the error "Outside start No. range" (error code: 1AA3H).
• Always turn ON the execution prohibition flag at the same time or before turning ON the positioning start signal. Prereading
may not be started if the execution prohibition flag is turned ON during Ta after the positioning start signal is turned ON. The
pre-reading start function is invalid if the execution prohibition flag is turned ON after positioning start with the execution
prohibition flag OFF. (It is made valid at the next positioning start.)
