Explanation
The indicated motor (#) has been
driven hard for too long a period of
time. The servo system has disa-
bled power to protect the robot
hardware.
The servo system has detected an
electrical or physical condition that
resulted in an encoder fault.
The indicated motor was not track-
ing the commanded position with
sufficient accuracy as set by
the configuration.
The dual-channel brake circuit has
reported a cyclic check error.
The power system has unexpect-
edly turned off power.
Overvoltage in the highvoltage DC
bus to the regenerative energy
dump circuit.
The regenerative energy dump cir-
cuit has exceeded its max short-
term dump rating.
Contact your local OMRON sup-
port.
An inrush error was detected by
the power sequencer. This means
the high-voltage DC bus failed to
rise at the expected rate when
power was enabled.
Corrective Action
•
Turn High Power back ON and
reduce the speed or acceleration
for the motion that was in prog-
ress or for motions that preceded
the message.
Refer to the eV+ Language Refer-
ence Guide (Cat. No. I605) for
more information.
Turn on high power and try to per-
form the motion at a
slower speed. Make sure that noth-
ing is obstructing the robot's mo-
tion. If the error continues, contact
your local OMRON support.
Contact your local OMRON sup-
port.
This can occur if High Power is
abruptly removed during the High
Power enable sequence. If it occurs
unexpectedly, contact your local
OMRON support.
