Cause
Motor is turning faster
than the highest allowed
frequency due to incor-
rectly set minimum/max-
imum frequency or the
motor rushes because of
too high supply voltage or
incorrect supply voltage
selection in parameter
95.01 Supply voltage.
-
Cyclical communication
between drive and field-
bus adapter module A or
between PLC and fieldbus
adapter module A is lost.
User load curve: Signal has
been too long under the
underload curve.

Diagnostics 165
What to do
Check minimum/maximum fre-
quency settings, parameters 30.13
Minimum frequency and 30.14
Maximum frequency.
Check used supply voltage and
voltage selection parameter 95.01
Supply voltage.
Contact your local ABB representat-
ive, quoting the auxiliary code.
Check the status of fieldbus com-
munication. Check parameter
groups 50 Fieldbus adapter (FBA),
51 FBA A settings, 52 FBA A data in
and 53 FBA A data out. Check cable
connections and communication of
master.
See parameter 37.04 ULC underload
actions.
