7310 Overspeed Motor is turning faster than
highest allowed speed due to
incorrectly set
minimum/maximum speed,
insufficient braking torque or
changes in load when using
torque reference.
Check minimum/maximum speed
settings, parameters 30.11 Minimum
speed and 30.12 Maximum speed.
Check adequacy of motor braking torque.
Check applicability of torque control.
Check need for brake chopper and
resistor(s).
73B0 Emergency ramp
failed
Emergency stop did not finish
within expected time.
Check the settings of parameters 31.32
Emergency ramp supervision and 31.33
Emergency ramp supervision delay.
Check the predefined ramp times
(23.11…23.15 for mode Off1, 23.23 for
mode Off3).
7510 FBA A communication
Programmable fault: 50.02
FBA A comm loss func
Cyclical communication
between drive and fieldbus
adapter module A or between
PLC and fieldbus adapter
module A is lost.
Check status of fieldbus communication.
See user documentation of fieldbus
interface.
Check settings of parameter groups 50
Fieldbus adapter (FBA), 51 FBA A
settings, 52 FBA A data in and 53 FBA A
data out.
Check cable connections.
Check if communication master is able to
communicate.
8001 ULC underload fault User load curve: Signal has
been too long under the
underload curve.
See parameter 37.04 ULC underload
actions.
8002 ULC overload fault User load curve: Signal has
been too long over the
overload curve.
See parameter 37.03 ULC overload
actions.
80A0 AI supervision
Programmable fault:
12.03 AI supervision
function
An analog signal is outside the
limits specified for the analog
input.
Check signal level at the analog input.
Check the wiring connected to the input.
Check the minimum and maximum limits
of the input in parameter group 12
Standard AI.
