35:battery empty When switching on the inverter, it
was determined that the voltage
of the battery has fallen below the
minimal voltage of the encoder.
Referencing of the axis has been
deleted. The backup battery is no
longer able to retain the position
in the encoder over the time dur-
ing which the inverter in switched
off.
• Referencing the axis.
• Replace the AES battery before the next time the in-
verter is switched off. Note also the Absolute Encod-
er Support AES operating instructions (see section
1.3 Other manuals).

Resolution Level Response Fault counter
The temperature measured by the device
sensor exceeds the permitted maximum
value or has fallen below the permitted min-
imum value. The permitted temperatures
are saved in the power stage of the inverter.

are too high or too low.
Correct the ambient temperature of
the inverter.
Take suitable measures to match the
ambient temperature to the operating
conditions of the inverter.
