Cause
Motor is turning faster than
highest allowed speed.
Emergency stop did not finish
within expected time.
Maximum allowed output fre-
quency exceeded.
Motor is turning faster than the
highest allowed frequency due
to incorrectly set minimum/max-
imum frequency or the motor
rushes because of too high sup-
ply voltage or incorrect supply
voltage selection in parameter
95.01 Supply voltage.
-
Cyclical communication between
drive and fieldbus adapter mod-
ule A or between PLC and field-
bus adapter module A is lost.
User load curve: Signal has been
too long under the underload
curve.
Underload occurred between
speed point 37.11 ULC speed
table point 1 and 37.12 ULC
speed table point 2.
Underload occurred between
speed point 37.12 ULC speed
table point 2 and 37.13 ULC
speed table point 3.
Underload occurred between
speed point 37.13 ULC speed
table point 3 and 37.14 ULC
speed table point 4.
Underload occurred between
speed point 37.14 ULC speed
table point 4 and 37.15 ULC
speed table point 5.
User load curve: Signal has been
too long over the overload curve.
Overload occurred between
speed point 37.11 ULC speed
table point 1 and 37.12 ULC
speed table point 2.
Overload occurred between
speed point 37.12 ULC speed
table point 2 and 37.13 ULC
speed table point 3.
What to do
Check the minimum/maximum speed set-
tings, parameters 30.11 Minimum speed
and 30.12 Maximum speed, motor braking
torque, torque control, brake chopper and
resistor(s).
Check predefined ramp times (23.11...23.15
for mode Off1, 23.23 for mode Off3).
Check the auxiliary code.
Check minimum/maximum frequency set-
tings, parameters 30.13 Minimum frequency
and 30.14 Maximum frequency.
Check used supply voltage and voltage se-
lection parameter 95.01 Supply voltage.
Contact your local ABB representative,
quoting the auxiliary code.
Check the status of fieldbus communication.
Check parameter groups 50 Fieldbus ad-
apter (FBA), 51 FBA A settings, 52 FBA A
data in and 53 FBA A data out. Check cable
connections and communication of master.
