Replacing the fan

Requirement
Replace the fan if a warning is output by the temperature monitoring function as a result of a
fan defect.
The SIMOTION D410 fans switch on depending on the internal module temperature. If the
temperature reaches impermissible values, this is signaled by a warning at the drive end:
A1009: CU warning: Control Unit overtemperature
In this case, the temperature (CU parameter r0037[0]) of the SIMOTION D410 has exceeded
the specified limit value.
Remedy:
● Check the supply air for the SIMOTION D410.
● Check the fan for the SIMOTION D410.
The warning will automatically disappear as soon as the limit value is undershot.
If the fan is defective, it must be replaced.
The fan can be ordered as spare part, see "Spare parts and accessories" in the
SIMOTION D410 Manual.
