08 Fault tracing
A6A7 System time not set System time is not set. Timed
functions cannot be used and
fault log dates are not correct.
Set the system time manually or connect
the panel to the drive to synchronize the
clock. If basic panel is used, synchronize
the clock through the EFB or a fieldbus
module.
Set parameter 34.10 Timed functions
enable to Disabled to disable the timed
functions if they are not used.
A6B0 User lock is open The user lock is open. Close the user lock by entering an invalid
pass code in parameter 96.02 Pass
code. See section User lock (page 151).
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 unit reboot (either by
cycling the power or through parameter
96.08 Control board boot) is required to
validate any changes in the hardware
settings.
A6E6 ULC configuration User load curve configuration
error.
Check the auxiliary code (format XXXX
ZZZZ). “ZZZZ” indicates the problem
(see actions for each code below).
0000 Speed points inconsistent. Check that each speed point (parameters
37.11…37.15) has a higher value than
the previous point.
0001 Frequency points inconsistent. Check that each frequency point
(37.20…37.16) has a higher value than
the previous point.
0002 Underload point above
overload point.
Check that each overload point
(37.31…37.35) has a higher value than
the corresponding underload point
(37.21…37.25).
0003 Overload point below
underload point.
A780 Motor stall
Programmable warning:
31.24 Stall function
Motor is operating in stall
region because of e.g.
excessive load or insufficient
motor power.
Check motor load and drive ratings.
Check fault function parameters.
A792 Brake resistor wiring Brake resistor short circuit or
brake chopper control fault.
For drive frames R6 or larger.
Check brake chopper and brake resistor
connection.
Ensure brake resistor is not damaged.
