History Monitor Function
This function monitors the start history, error history, and warning history stored in the buffer memory of RD75 during the
operation monitoring.
Start history
The start history of past 16 records of operations such as the positioning operation, JOG operation, and manual pulse
generator operation can be monitored. Once 16 records are stored, the oldest record is overwritten with the latest record.
Therefore, the latest 16 history records are stored at all times. This function allows users to check the operation sequence
(whether the operations have been started in a predetermined sequence) when the system is started.
The start history can be checked using the intelligent function module monitor window. The following describes the check
method.
