Possible cause
Actual status of mechanical brake
remains different from the control
signal for longer than what is
defined.
The minimum water level is not ok.
The maximum water level is not ok.
The data connection between the
PC and frequency converter is
broken.
The thermistor input has detected
an increase of motor temperature.
Maintenance counter has reached
the alarm limit.
Maintenance counter has reached
the alarm limit.
Maintenance counter has reached
the alarm limit.
Maintenance counter has reached
the alarm limit.
Non-existing ID number is used for
mapping values to Fieldbus Process
Data Out.
Not possible to convert one or more
values for Fieldbus Process Data
Out.
Overflow when mapping and
converting values for Fieldbus
Process Data Out (16-bit).
Start command is active and was
blocked in order to prevent
unintentional rotation of the motor
during the first startup.
Maximum number of 5 simultaneous
active fieldbus or PC tool
connections supported by the
application exceeded.
The Soft fill function in the PID
controller has timed out. The wanted
process value was not achieved
within the time set.
PID controller: Feedback value
outside of supervision limits (and the
delay if set).
PID controller: Feedback value
outside of supervision limits (and the
delay if set).
Remedy
Check the status and
connections of the mechanical
brake.
Check settings and water level
status.
Check settings and water level
status.
Check motor cooling and load.
Check thermistor connection.
(If thermistor input is not in use,
it has to be short circuited)
Carry out the required
maintenance and reset counter.

Check parameters in Fieldbus
Data Mapping menu.
The value being mapped may
be of an undefined type. Check
parameters in Fieldbus Data
Mapping menu.
Reset drive to restore normal
operation. Whether restart is
needed depends on the
parameter settings.
Remove excessive active
connections.
Check for any pipe bursts.
Check settings.
Check settings.
