Fault
This LED lights up each time there is at least an alarm signaling.
When the LED is lighted up, the driver is not operative and the motor is
without supply (observe that also in this condition the yellow LED
continues in its own activity as described in the previous chapter).
In presence of an alarm the red LED lights up and starts a sequence of
flashing related to the kind of problem found.
The following table shows the association between the number of flashes
and the error found.
If more than a problem occurs at the same time the lighting flashes
sequences associated to each one of them are cyclically executed. If for
example the over temperature condition occurs together with the over
voltage one, the LED will flash twice and then three times alternatively till
when the malfunction signaling will be removed.
The driver features grant at least a visualization cycle for each activated
alarm. For this reason it is not possible to remove an alarm before the first
visualization cycle is finished.
Note that each error signaling can be removed differently according to how
the driver has been set (for a close examination see chapter 5.2.5 Alarms
and Protections conditioning).
For a detailed description on the various alarms and protections see chapter
5.5 Protections.
When in the driver the
Loader (an always resident small software necessary
for the firmware update) is active, the Fault LED remains always on.

Problem description
1 Under voltage, the supply voltage is inferior to Vpl value
2 Over voltage, the supply voltage is superior to Vph value
3 Over temperature, the heat sink voltage is superior to Tchh
4 Phase-to-phase short circuit, one or two phases are in short circuit
5 Phase-to-ground short circuit (GND), phase in short circuit with ground
6 Phase-Vp short circuit, one phase is in short circuit with power supply
7 Interrupted phase A, connection between driver and motor is missing
8 Interrupted phase B, connection between driver and motor is missing
