9.2.4.2. Reset errors
To clear the error history log in both the low and high kit, scroll using the +/- keys until the LED
display shows:
RESET ERRORS ?
press ENTER to clear the error history log, and return to the upper menu level by pressing CLEAR
for a few seconds.
9.2.4.3. COM.Fault
This is a counter that display the number of errors in serial communication between the upper and
the lower kit. This counter increase each time a communication fault is detected. Scroll using the
+/- keys until the display shows:
COM.FAULT X
To reset it press ENTER, the LED display shows:
RESET COM.FAULT?

9.2.4.4. View Errors
For every error generated by the machine, the error history log records the information in the table
below:
• Counter;
• Error Code;
• Voltage when the error occurred;
• Current * 10 when the error occurred;
• Speed km/h when the error occurred.
The correspondence between error codes and descriptions is given in the table below:

Description
OH 1 Overheating of the heat sinks of the AT drive and of the PFC.
OC 2 Overcurrent, even if only transient, on the inverter output.
UU 3 Undervoltage condition, due to an even transient drop in line voltage.
OU 4 Overvoltage.
PE 6
EEPROM error. Is generated when there is an error detected in the data
stored on the EEprom.
EdC1 7 Elevation motor encoder error.
OtM 9 AC motor thermal cutout open.
Oli 10
Inverter overload caused by a DC current exceeding, for the maximum
allowed time (I
2
t), the maximum permissible threshold for the inverter.
OLm 11
Motor overload caused by a DC current exceeding, for the maximum
allowed time (I
2
t), the maximum permissible threshold for the motor in
question.
