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).
