YNCHRONIZATION
I A013 - Missing Synchronization
Failure of the circuits supplying the synchronizing signals of the mains three-
S
phase voltage. This alarm may trip only when the ENABLE digital input is active.
Set continuous autoreset through parameter C093.

ORQUE URING
I A015 - AutoTune Error
During the current auto tuning stage (P001=1), the motor torque allows the
S
motor to rotate at M001 (nFdbk) value higher than approx. 1.5%, due to any
residual magnetism, even if the field is off. This alarm may also occur if during
the armature resistive drop autotuning (P001=3), the motor torque allows it to
rotate at M001 (nFdbk) speed higher than approx. 1.5% in tacho or enP/Nr
feedback mode, or higher than 10% in enP/Nr feedback mode, because of any
residual magnetism, even if the field is off.
In this case, it is necessary to lock mechanically the motor to perform the
automatic calibration.
O
AINS VERVOLTAGE
I A016 - Mains OverVoltage
S Value M009 of power section mains voltage (Vmains) has exceeded the lowest
limit between the following values: 1) the maximum voltage to be applied
(factory-set) increased by 10%. 2) The rated voltage (C030) increased by 20%.
This alarm may trip only when the ENABLE digital input is active. It may be
delayed through parameter C141 and disabled through parameter C157.
U
AINS NDERVOLTAGE
A017 - Mains UnderVoltage
I
S Value M009 of power section mains voltage (Vmains) is under the rated voltage
limit (C030) for a value equal to 15% in case of drives which are able to
regenerate mains energy (2nd and/or 4th quadrant enabled). Otherwise, it
proves a 20% decrease in case of drives which are not able to regenerate
mains energy (2nd and 4th quadrant disabled). This alarm may occur only when
the ENABLE digital input is active. It may be delayed through parameter C141
and disabled through parameter C157. Set continuous autoreset through
parameter C093.
The alarm delay (if any) set through par. C141 is active only if the supply voltage
is not under 3/4 of the threshold value (85% or 80% of the rated value) and if no
regenerative braking is in progress. In any other case, the alarm will immediately
trip.
