Cooling SIMOTION D4x5 and buffering data
Functions of a fan/battery module
The fan/battery module has the following tasks:
● CPU cooling
● Buffering of the SRAM and the real-time clock if the SuperCap is insufficient.
The Control Unit monitors the temperature and the functioning of the fan.
Cooling the SIMOTION D4x5
If there is insufficient free convection for heat dissipation of the Control Unit and the supply air
temperature rises above the permitted range, an external fan/battery module must be fitted to
the bottom of the D4x5. This module can be installed without further measures on a Control
Unit where there is insufficient ventilation in the control cabinet.
