Power supply
External 24 V power supply
The control unit is supplied by an external 24 V power supply (e.g. SITOP).
The tolerance range for the input voltage of the SIMOTION D4x5-2 is between 20.4 and
28.8 VDC.

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
A temporary voltage dip (> 3 ms) results in the supply falling below the minimum
