For reading of log data, turn off the log command signal (LOGC). If log data is
read while the log operation being performed signal (LOGO) is turned on, the
reading of log data error (LOGRE) is turned on.
reading of log data error (LOGRE) is turned on.
Log data is stored using a ring buffer format in the log data buffer area of the
position board; however, when transferred to the dual port memory, the data
is transferred from the oldest (oldest is transferred first) in order.

7.13.7 Log acquiring selection
By setting the log acquiring selection (parameter No.0040 to 0042), the axis No. and system for which the log
to be acquired can be set.
When the number of log events to be memorized is not enough, set the events (axis and system) for which log
is to be acquired, using this function.
(1) System parameter
to be acquired can be set.

Note 1. When all the system parameters of the log acquiring selection (parameters No. 0040 to 0042) are set to 0000h (initial value),
log for all axes and systems will be acquired.
2. Since the parameter for the log acquiring selection is not determined before the system startup, log for all axes and systems will
be acquired.
