Diagnostics
3.2 Diagnostics via STARTER
– 0.0% is mapped onto 2.49 V
– 100.0% is mapped onto 4.98 V
– 100.0% is mapped onto 0.00 V
Offset
The offset is applied additively to the signal to be output. The signal to be output can thus be
displayed within the measuring range.
Limitation
● Limitation On
● Limitation off
Example of a measurement
Assumption:
The actual speed (r0063) is to be output for a drive via measuring socket T1.
How do you do it?
1. Connect and set the measuring device.
2. Interconnect the signal (e.g. STARTER).
3. Parameterize the signal characteristic (scaling, offset, limitation).

Overview of important parameters (see SINAMICS S120/S150 List Manual)
Adjustable parameters
● p0771[0...2] CI: Measuring sockets signal source
● p0777[0...2] Measuring sockets characteristic value x1
● P0778[0...2] Measuring sockets characteristic value y1

If signals are output outside the permissible measuring range, the signal is limited to 4.98
V or to 0V.
The output of signals outside the permissible measuring range causes a signal overflow.
In the event of an overflow, the signal jumps from 0 V to 4.98 V or from 4.98 to 0 V.
Interconnect the connector input (CI) belonging to the measuring socket with the desired
connector output (CO).
CI: p0771[1] = CO: r0063
