Alarm Remedies
0
No alarm
1
DC circuit overvoltage
Check the three-phase power line (max 480V
+ 10%).
Check the break circuit and the braking
resistor
2
DC circuit undervoltage
Check the three-phase power line.
3
Overcurrent
Check the motor connections and any phase-
phase or phase-ground short-circuits. Check
the motor data.
4
FBK error (resolver or
encoder)
Check the connections of the speed loop and
the connectors on both sides (drive-motor).
Check the feedback parameters.
5
PTC motor alarm
Check the PTC connection cable. Check the
parameters Pr33 (I
nom
) and Pr19 (I
peak
).
6
Power module
overtemperature
Check the cooling fans and for any
restrictions to air flow.
Check the braking cycle.
Check the ambient temperature in the electric
cabinet where the drive is installed, as well as
the ambient temperature outside the cabinet.
7
External alarm
Depends on the application (b41.7 – see
Pico-PLC program)
8
Auxiliary alarm
Depends on the application (b41.8 – see
Pico-PLC program)
10 (*)

and on again the drive and repeat
programming.
11 (*)
Parameter check sum
Set and save default parameters, switch off
and on again the drive and repeat
programming.
14

Check the braking cycle.
15
Default parameters
Set and save default parameters, switch off
and on again the drive and repeat
programming.
17 (**)
Hardware broken
Internal damage, to send to repair.
22
Ambient over temperature
The ambient temperature in the electric
cabinet is excessive (>45°C). Check the
cooling fans and for any restrictions to air
flow.
