11.2 PSD (Power+) alarm code
In the below table we reported a quick description about the PSD alarm code could occur in the unit with
the possible causes and solutions.
The PSD (Power+) alarm code is reported in the alarm masks or in the alarm logs (please find an example
in the below picture).

1
Overcurrent
The drive has detected a current supplied
that is too high due to:
- sudden strong load increase;
- acceleration that is too high;
-
wrong parameters values or inadequate
motor.
Check the load, the dimension of the motor
and the cables. Decrease
acceleration. Check
the motor parameters..
2
Motor overload
The current supplied has exceeded the
motor rated current over the maximum time
accepted
Check the load, the dimension of the motor
and the cables. Check the motor parameters.
3
Overvoltage
The DC voltage of the intermediate circuit has
exceeded the limits envisioned due to:
- deceleration that is too high;
- high over-
voltage peaks on the power
supply network.
Decrease deceleration.
4
Undervoltage
The DC voltage of the intermediate circu
it is
below the limits envisioned due to:
- insufficient power supply voltage;
- fault inside the drive.
In the event of temporary cut
-
off of the
power supply, reset the alarm and re-
start
the drive. Check the power supply voltage.
5
Drive overtemperatur
e
The temperature inside the drive has
exceeded the maximum level allowed.
Check that the quantity and flow of cooling
air are regular. Check that there is not dust in
the heat sink. Check the environment
temperature. Ensure that the switching
frequency i
s not too high with respect to the
environment temperature and the motor
load.
6
Drive
undertemperature
The temperature of the drive is inferior to the
minimum level allowed.
Warm up the ambient where the drive is
installed.
7
Overcurrent HW
The drive has detected an istantaneous
current supplied that is too high due to:
- sudden strong load increase;
- motor cables short circuit;
Check the load, the dimension of the motor
and the cables. Check the motor parameters.
