ABB ACQ80-04 User Manual

204 Fault tracing
1 Slip frequency is too small. Check the settings of the motor
configuration parameters in groups 98
and 99.
Check that the drive is sized correctly for
the motor.
2 Synchronous and nominal
speeds differ too much.
3 Nominal speed is higher than
synchronous speed with 1 pole
pair.
4 Nominal current is outside
limits
5 Nominal voltage is outside
limits.
6 Nominal power is higher than
apparent power.
7 Nominal power not consistent
with nominal speed and
torque.
A6A5 No motor data Parameters in group 99 have
not been set.
Check that all the required parameters in
group 99 have been set.
Note: It is normal for this warning to
appear during the start-up and continue
until the motor data is entered.
A6A6 Voltage category
unselected
The voltage category has not
been defined.
Set voltage category in parameter 95.01
Supply voltage.
A6A7 System time not set System time is not set.
A6B0 User lock is open The user lock is open, ie. user
lock configuration parameters
96.100…96.102 are visible.
Close the user lock by entering an invalid
pass code in parameter 96.02 Pass
code. See section User lock (page 52).
A6B1 User pass code not
confirmed
A new user pass code has
been entered in parameter
96.100 but not confirmed in
96.101.
Confirm the new pass code by entering
the same code in 96.101. To cancel,
close the user lock without confirming the
new code. See section User lock (page
52).
A6D1 FBA A parameter
conflict
The drive does not have a
functionality requested by a
PLC, or requested functionality
has not been activated.
Check PLC programming.
Check settings of parameter groups 50
Fieldbus adapter (FBA).
A6E5 AI parametrization The current/voltage hardware
setting of an analog input does
not correspond to parameter
settings.
Check the event log for an auxiliary code.
The code identifies the analog input
whose settings are in conflict.
Adjust either the hardware setting (on the
drive control unit) or parameter
12.15/12.25.
Note: Control board reboot (either by
cycling the power or through parameter
96.08 Control board boot) is required to
validate any changes in the hardware
settings.
A780 Motor stall
(Programmable
warning: 31.24 Stall
function)
Motor is operating in stall
region.
Check motor load, drive ratings and fault
function parameters.
Code
(hex)
Warning / Aux. code

on assistant control
panel and drive
composer)
