buffer memory of the QD75 during operation.
[1] Starting history
Sixteen starting history logs of operations such as positioning operation, JOG
operation, and manual pulse generator operation can be monitored. When the number
of logs exceeds 16, the latest log overwrites the oldest log so that the latest 16 logs
can be monitored all the time. This function allows users to check the operation
sequence (whether the operations have been started in a predetermined sequence) at
system start-up.
