20 Not Used 1
21 External fault
Condition: External alarm present.
A digital input has been programmed as an external alarm, but the +24V voltage is not avail-
able on the terminal.
Solution: Check that the terminal screws are tight
22 Not Used 2
23 Overspeed
Condition: Motor overspeed alarm. The motor speed exceeds the limits set in the PAR 670
Speed ref top lim and PAR 672 Speed ref bottom lim parameters.
Solution:
- Limit the speed reference.
- Check that the motor is not driven in overspeed during rotation.
24 Speed ref loss
Condition: Speed reference loss alarm
Occurs if the difference between the speed regulator reference and the actual motor speed is
more than 100 rpm. This condition occurs because the drive is in the current limit condition. It is
only available in the Flux Vect OL mode.
Solution:
- Check the drive load conditions
25 Emg stop alarm
Condition: Emergency stop alarm. The Stop key on the keypad was pressed with the Stop
key mode parameter set to EmgStop&Alarm in case of Remote->Terminal Strip or Remote-
>Digital or Local->Terminal Strip mode.
Solution:
Eliminate the reason for which the Stop key on the keypad was pressed and reset the drive.
26 Power down Condition: The drive was enabled with no supply voltage at the power section.
Solution: Emergency stop alarm. The Stop key on the keypad was pressed with the Stop
key mode parameter set to EmgStop&Alarm in case of Remote->Terminal Strip or Remote-
>Digital or Local->Terminal Strip mode.
27 Broken belt
Condition: Occurs if torque required from motor falls below a programmed threshold (PAR
7702) and if speed exceeds a programmed threshold (PAR 7706).
Solution: Check system mechanics.
28 End curve
Condition: The value of the feedback signal (for example, pressure transducer) is below the
reference value and rotation speed is higher than the threshold set in parameter 7712. The
alarm is generated if this condition persists for a time equal to the value set in parameter 7714
Solution:
• Check configuration of parameters on menu 26.11.
• Check for system leakages.
• Check the feedback sensor.

30
Dry pump
No flow
Condition: The value of delivered power (parameter 7752) is below the limits defined by the
minimum power curve.
Solution:
• Check configuration of parameters on menu 26.11.
• Check for system leakages.
31 Clean alarm
Condition: If cleaning cycles are performed too frequently, there may be a problem with the
pump that requires the attention of an operator. In that case a specific alarm is generated. Only
cleaning cycles that start following an external event (digital signal) or analog measurement
are considered for this alarm.
Solution: Check the system..

Plc1 fault
...
Plc8 fault
Condition: Enabled application developed in the IEC 61131-3 environment has found the condi-
tions for generating this specific alarm to be true. The meaning of the alarm depends on the
type of application. For more information, refer to the documentation concerning the specific
application..
