A001 - Field Failure
The alarm trips:
S
a. When running, in case of a field current failure.
b. Alternatively, during the current auto tuning if the field current has been
detected.
The field current detection control is made through the comparison between par.
M018 (Ifld) and an internal threshold equal to 7.5% of the value of C010 (value
of the nominal field current).
This alarm may be disabled through parameter C150.
This alarm trips only when the drive is running. It trips after a 2s internal delay.

A002 - Heatsink Trip
The contact relating to the thermo switch assembled in the drive heatsink is
S
open, thus signalling that the max. allowable temperature has been exceeded.
When the thermo switch contact is closed, LED SA in the control board turns on.
After the connection of the mentioned alarm, some minutes should generally
elapse before performing a reset.

A003 - Armature OverCurrent
The instantaneous value (peak value) of armature overcurrent M004 (Iarm) has
S
exceeded 200 % of the drive rated current, or 300 % of the drive rated current
under overlimit conditions.

A004 - Load Loss
I
The alarm trips:
S
a. When one of the two connections to the load terminals is cut off.
b. If the DC side fuse (if any) is blown.
This alarm may be disabled through parameter C151.

A006 - Unstable Mains Frequency
S
The mains frequency voltage varies more than the max. allowable value, equal
to 500ms between two mains periods. This alarm may occur only when the
ENABLE digital input is active. Set disabling through parameter C153 and
continuous autoreset through parameter C093.
