MTn_ZS_F and MTn_ZS_S
Display of the measuring time determined
The measuring time is specified as a 16-bit value with a resolution of 0.25 μs.
Features of the central probe
● The time stamps from probes in more than one drive can be transferred simultaneously in
a single telegram.
● The time in the controller and drive unit is synchronized via the CU_STW and the
CU_ZSW.
Note: The controller must support time synchronization!
● A higher-level controller can then use the time stamp to determine the actual position
value of more than one drive.
● The system outputs a message if the measuring time determination function in the probe
is already in use (see also p0488, p0489, and p0580).
