5.7.1
Cooling the SIMOTION D410-2
Overview
A fan is always required for operation of the SIMOTION D410-2. This is included in the scope
of delivery of the D410-2 control unit. The fan operates temperature-controlled and is switched
on depending on the air intake temperature and the CPU load.
Fan faults
Fan faults are indicated as follows:
● Entry in diagnostic buffer
● Indicated via system variable
● Calling the PeripheralFaultTask
If a fan fault occurs or the fan is unplugged, the module continues to run. The controller goes
into FAULT state when overtemperature occurs (temperature threshold 2 exceeded), whereby
all LEDs flicker red. The state can only exited through power off/on
For further information on the evaluation of fan faults, see Section Overview of fan states
(Page 99).
5.7.2 Overview of fan states
Evaluation of fan faults

Fan faults are detected through a cyclic fan test or when a malfunction is determined when
the fan is activated (fan does not rotate or fan rotates at too low a speed).
Fan faults are signaled by the following diagnostic buffer entry:
Fan on the module is defective.
