with a fault code or a text
message indicating the fault type will replace the name of the motor drive on the
display in the idle mode. Some of these faults can be corrected by a relay operator

automatically be cleared.
Fig. 3.3.2.3.-2 Warning with text message
If more than one type of fault occur at the same time, one single numeric code which
indicates all the faults will be displayed. For instance, “2049” implies two faults: the
battery is low and the temperature sensor RTD6 is faulty. The code is composed of
the weighting factors assigned to each fault type as follows: 1 + 2048; see
Table
