Cause
Phase search must be completed
to control a motor with type
"encoder only"
This error indicates that a
feedback type of halls only or
Encoder + Halls is used and has
detected an error. If this is so the
halls sensor state is checked by
the drive and that the Hall state
detected is illegal (0 or 7).
This indicates that either there has
been a total break or total
disruption with the encoder
signals.
Power supply to encoder has been
lost or has dropped below the
minimum level for the selected
encoder type.
Note: encoder voltage is supplied
by the drive.encoder power is
given from power board, then
transferred from 8v to 5v by
control board.
EtherCAT or EPL PDO data from
the manager (MN) to the remote
axis (CN) has been lost. This error
occurs if the remote axis detects
that at least two consecutive PDO
packets have not been received
correctly.
Unable to load motion on the
remote axis. Generally speaking,
this error indicates MML in drive is
not ready for operation.
What to do
Phase search must be completed to
control a motor with type "encoder only"-
if it does not finish successfully check
encoder settings in drive and check the
correct number of motor poles has been
configured.
This error would normally indicate a faulty
encoder in the motor (the encoders
include simulated hall signals) or bad
wiring to the motor encoder. Check the
quality of installation, wiring and encoder
type selection.
Note: You can use Mint Workbench to
scope Encoder Hall State to look for
problems.
Check the quality of installation, wiring
and encoder type selection.
Note: You can use Mint Workbench to
scope Encoder Hall State and Encoeder
to look for problems.
Note: To get more information on this
error connect to the Drive with Mint
Workbench go to "Parameters > Encoder
> Channel 0 > Encoder
Parameter(Encoder0, Fault Register)" If
this contains a value other than 0 you can
use this value to give you more help on
the error. See help file subject:
ENCODERPARAMETER. Check all
earthing and shielding arrangements are
as per the instruction manual.
Check that there are no shorts in the
encoder wiring to the encoder supply
(e.g. ensure the shields are not shorting
to the supply or other signal pins). If the
wiring is OK and the problem persists
then it is likely one of the internal power
supplies is failing.
This error will occur on the drive if it has
lost its connection to the Manager. Check
that the Manager is running, configured
correctly and the network is operating
correctly.
This can be caused by a number of
reasons, such as incorrect operating
mode, the motor brake being enabled or
the move buffer being full.
