24. THERMIC SENSOR KO
The range of inverter temperature sensor is always checked and a warning is signalled
if it is out of range.
When this alarm is signalled, check the connection of the sensors.
25. CAN BUS KO
The diagnosis of the CAN-BUS line is present only if the inverter uses this link (de-
pends on the software version). It is signalled if the inverter does not receive any mes-
sage from the CAN-BUS line. First of all, check the wiring. If it is ok, the problem is on
the logic board, which must be replaced.
26. BATTERY LOW
If the "battery check" option is ON, a battery discharge algorithm is carried out. When
the charge level is 10% , this alarm is signalled and the current is reduced to the half of
the programmed level.
27. MOTOR TEMPERATURE
Motor temperature is greater than the set value (see the adjustment "MOTOR
OVERTEMP"). This is just a warning: no control correction is taken.
