Description 1: MRm object changed to True
It is activated when the comparative object of a multi-purpose register (MRm register) meets the comparison condition.
As shown in the table, the MRm register corresponding to 4 synchronous action sets is fixed. The comparative object
and comparison condition can be set by multi-purpose register mode setting command (20h). For instance, when the
comparative object of MR0 register is set to the logical position counter (LP) and comparison condition is set to
“comparative object
≧
MRm”, if the value of the logical position counter is equal to or larger than MR0 value, it will be
activated. If comparison condition is already True when the synchronous action is enabled, the synchronous action is not
activated at that time. After it returns to False, and then if it again changes to True, the synchronous action will be
activated.
Description 2: The internal timer is up
It is activated when the internal timer is up. The timer value can be set by timer value setting command (16h). The timer
can be started by timer-start command (73h) or the other synchronous action sets.
Description 3: Change of driving state
As shown below, it is activated when the change of a driving state occurs during the driving.
