Cause
The drive is configured to use a
Serial Encoder and it is not able to
provide position information.
The three phase drive has
detected that one of the AC supply
phases may been lost. The drive
can normally only operate using a
three phase supply. MotiFlex e100
drives have dedicated phase
monitoring hardware, MotiFlex
e180 drives monitor the ripple on
the dc bus and if this becomes
excessive then they assume an
input phase has been lost
PDO data from the remote axis
(CN) to the manager (MN) has
been lost. This error occurs if the
manager detects that at least two
consecutive PDO packets have
not been received correctly.
When controlling an axis using
Real time Ethernet one of the
PDOs sent to the drive were out of
range. This is often the velocity
reference PDO and can be caused
when an axis is geared to a master
axis/encoder and the master
position/encoder value is changed
via the program to a new value
causing an infinite velocity
demand
Either one or both of the Safe
Torque Off inputs is not powered.
This error can occur only when the
drive is enabled.
Fault tracing 137
What to do
The encoder may take several seconds
to become ready and this error will be
generated if an attempt is made to enable
the axis before the encoder is ready.
This error can also occur if the resolution
configured on the drive is not compatible
with the encoder. The axis will be crash
stopped and disabled.
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 the connection of the input
phases. If the connections are OK and a
MotiFlex e180 is tripping spuriously (e.g.
because the application requires harsh
repeated accel and decel cycles) then
you can disable phase loss detection
using PHASELOSSMODE(0) = 0
This error will occur on the NextMove
e100 if it detects a drive disappears from
the network. This may be "normal" for an
optional node (and the error must be
handled via the ONERROR event). If this
error is unexpected check the drive is not
resetting and check the integrity of the
Ethernet (EPL) cabling
Connect to the drive whilst the error is
active and use the Error Log to determine
which PDO is out of range. If it's velocity
then check the Mint program to ensure
axes that are geared to master
references are not geared when those
master references position/encoder
values are written to
Check drive STO inputs, if used check
the wiring of the safety circuit or for open
guards or Emergency stops etc.
