continued: Fault codes
Possible cause
The data connection between the
PC and the drive is defective.
The motor temperature is too
high.
Maintenance counter has
reached the alarm limit.
Maintenance counter has
reached the fault limit.
Maintenance counter has
reached the alarm limit.
Maintenance counter has
reached the fault limit.
Maintenance counter has
reached the alarm limit.
Maintenance counter has
reached the fault limit.
The ID number that is used to
map the values to Fieldbus
Process Data Out is not valid.
It is not possible to convert one
or more values for Fieldbus
Process Data Out.
There is an overflow when the
values for Fieldbus Process Data
Out (16-bit) are mapped and
converted.
The PID controller: The feedback
value is not in the supervision
limits and the delay, if you set the
delay.
The PID controller: The feedback
value is not in the supervision
limits and the delay, if you set the
delay.
The drive lowers the current limit
to protect itself from overheating.
This decreases also the output
frequency.
Subject to change without notice
Remedy
Check the motor cooling and the load.
Check the thermistor connection.
If the thermistor input is not used, you
have to short-circuit it.
Carry out the needed maintenance and
reset the counter.
Check the parameters in the Fieldbus
Data Mapping menu
The type of the value is undefined.
Check the parameters in the Fieldbus
Data Mapping menu.
