Test Point Port - Siemens SINAMICS PERFECT HARMONY GH180 Function Manual

The following functions performed by the SIB provide a signal directly to the modulator to shut
down all cell switching immediately:
• Inhibit or CR3 signal to modulator. Refer to Section Inhibit Input (Control Relay 3, CR3).

Test Point Port

The NXGPro+ Control has a dedicated test port for safe measurement of critical feedback signals.
A DIN41612 type connector is available on the main control board for breaking out the various
analog feedback signals to test points. The analog feedback signals do not have test points on
the main control board and are only available through this connector. In addition to the analog
signals, select FPGA signals are brought out as test points. The DIN41612 type connector allows
for either the use of a test point board or an automated data collection system to directly monitor
the analog feedback signals.
NOTICE
Risk of damage to equipment.
Do not attempt direct manual measurement of signals at the port connector.
This can cause damage to components.
Instead always directly measure signals via the test point board.
For correct use of the signals beyond the test point board, consult the design documentation for
proper scaling. Refer to the table below for details of the available signals.
