The cursor must be positioned on the “Signal selection” list box for the trace
concerned. Then activate the desired items by selecting them from the list box.
The options available for selection depend on the configuration and on which
functions are activated.
The measuring time is entered directly in the “Measuring duration” input box.
Direct input of pre- and post-triggering. With negative input values (leading sign
minus –) recording begins at the set time before the trigger event.
With positive input values (without leading sign) recording begins after the
trigger event.
Associated condition: Trigger time + measuring duration y 0.
The trigger type is selected from the “Trigger” drop-down list. The trigger always
relates to trace 1. Once the trigger condition has been fulfilled, traces 2 to 4 are
started at the same time.
Settable trigger conditions:
S No trigger, i.e. measurement begins when the Start soft key is activated
(all traces are started time-synchronized).
S Positive edge
S Negative edge
S Trigger event from the sub-program
Used to enter the trigger threshold directly.
The threshold is only effective with trigger types “Positive edge” and “Negative
edge”.
The unit refers to the selected signal.
Used to select the axis/spindle when the cursor is on the relevant “Axis/spindle
name” list box.
You can also select the axis/spindle by using the cursor in the drop-down list.
To start the trace function recording, press the Start soft key. The current mes-
sage is aborted by activating the Stop soft key or RESET.
