Siemens SIMOTION D455-2 - Interfaces and performance features

Note
If
the D4x5‑2 detects undervoltage, the module performs a RESET. If all LEDs are off, either
there is no power supply or the voltage level is too low.
When the voltage level is in the permissible range again, the D4x5‑2 restarts.
Undervoltages are detected when:
● The voltage level of the 24-V supply falls below the minimum permissible input voltage of
the D4x5-2
● A temporary voltage dip (> 3 ms) results in the supply falling below the minimum
permissible input voltage on the D4x5‑2.

Recommended power supply units and tables for calculating the current consumption for the
assembly
with SINAMICS S120 modules can be found in the "Control cabinet installation and
EMC booksize" chapter in the
