Measuring Mode 1 - Siemens SINUMERIK 840D sl Function Manual

8.5.2 Measuring mode
The measuring mode specifies whether trigger events must be activated in parallel or
sequentially in ascending sequence and defines the number of measurements to be taken.

Measuring mode 1

The user can program up to 4 different trigger events in the same position controller cycle.
The measurement signal edges are evaluated in chronological order.
● Up to two probes with two measuring signal edges each can be programmed for each
● Where six-axis modules are installed, measuring mode 1 is imaged on measuring mode
● The traversing velocity must be lower or equal to the shortest distance between two
Note
With this mode, the compensation value which was present when the last measuring signal
edge was received is calculated for all measured values.
Measuring mode 2
The user can program up to 4 different trigger events one after the other in the sequence
configured.
The evaluation of the measurement signal edges is active for one trigger event at a time and
occurs in the programmed sequence.
● Trigger events are detected only in the programmed sequence.
● The traversing velocity must be lower or equal to the shortest distance between two
Note
Measurement does not work on simulated axes!
Probe status
It is possible to scan the probe status directly in the part program and in synchronized
actions.
