Meaning Of Leds - Siemens Sinamics S120 Manual

Note
The digital inputs DI are isolated and refer to M_DI (X21.5 and X21.6).
The reference point of the digital outputs DO is the ground GND of the 24 V supply.
To parameterize the digital inputs or digital outputs, see the SINAMICS S120/S150 List
Manual.

Description
The electronics power supply is missing or outside the
permissible tolerance range.
The component is ready for operation.
Enable missing (input terminal)
Overtemperature of IGBT/braking resistor
Overcurrent trip
I t monitoring activated
2
Braking power monitoring triggered
Ground fault/short circuit
Note:
In the event of overtemperature, l
braking power monitoring, the fault will be
acknowledged automatically after a cooling down
phase. Manual acknowledgment is not possible.
The DC link voltage is not available, the electronics
power supply is missing or is outside the permissible
tolerance range.
The component is not active.
The DC link voltage is present.
The component is active. The DC link is being
discharged via the braking resistor.
