Trigger Setting
A trigger is a device for designating the timing of data access. For example, if you set the condition that the
speed feedback exceeds 100 min
-1
, you can check detailed servo operation after the point where that condition
is satisfied.
• Trigger (Trigger Conditions)
Set two trigger conditions: Trigger A and Trigger B.
By combining Trigger A and Trigger B, a total of three conditions can be set as follows
.
• Pre-trigger (0% to 99%)
Designate to what degree data is displayed in the graph before a trigger is applied.
• Trigger Target
Designate the object to which the trigger is applied. The selected objects can either be from the designated in
Data 1, 2, and 3, and I/O 1, 2, and 3, or "No Trigger".
If "No Trigger" is selected, the trigger will be applied at the time the
START
button is clicked. Also the set-
tings for "Trigger Level", "Trigger" (trigger type), and "Pre-Trigger" will be unavailable.
