[2] Precautions during control
(1) The time required to analyze the positioning data is up to 0.88ms
(LD77MS2/LD77MS4)/3.55ms(LD77MS16).
(2) 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.
(3) 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: Refer to Fig.
13.46).
(4) The data No. which can be executed 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: 543).
(5) Always turn ON the execution prohibition flag at the same time or before
turning ON the positioning start signal. Pre-reading 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.)
