A686 Checksum mismatch
Programmable warning:
96.54 Checksum action
The calculated parameter
checksum does not match any
enabled reference checksum.
Check that all necessary approved
(reference) checksums (96.56…96.59)
are enabled in 96.55 Checksum control
word.
Check the parameter configuration.
Using 96.55 Checksum control word,
enable a checksum parameter and copy
the actual checksum into that parameter.
A687 Checksum
configuration
An action has been defined for
a parameter checksum
mismatch but the feature has
not been configured.
Contact your local ABB representative for
configuring the feature, or disable the
feature in 96.54 Checksum action.
A688 Parameter map
configuration
Too much data in parameter
mapping table created in Drive
customizer.
See the Drive customizer PC tool user’s
manual (3AUA0000104167 [English]).
A689 Mapped parameter
value cut
Parameter value saturated eg.
by the scaling specified in
parameter mapping table
(created in Drive customizer).
Check parameter scaling and format in
parameter mapping table. See the Drive
customizer PC tool user’s manual
(3AUA0000104167 [English]).
A6A4 Motor nominal value The motor parameters are set
incorrectly.
Check the auxiliary code. See actions for
each code below.
The drive is not dimensioned
correctly.
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 Supply voltage
unselected
The supply voltage has not
been defined.
Set supply voltage in parameter 95.01
Supply voltage.
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 92).
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
92).
