Code Error message shown
on the display
Sub-code Description
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 PAR 1008 Stop key mode parameter set to EmgStop&Alarm.
Active in remote control mode (PAR 1012=1) both by using “Terminals” command or “Digital” commands and, in local
control mode (PAR 1012=0) by using “Terminals” command.
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 exter-
nal event (digital signal) or analog measurement are considered for this alarm.
Solution: Check the system.

Plc8 fault
Condition: Enabled application developed in the IEC 61131-3 environment has found the conditions 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..
XXXXH-X The XXXXH-X code indicates the reason for the error: make a note of this to discuss it with the service
centre.
Solution: Refer to the documentation concerning the enabled application.
