eCobra 600 and 800 Robots with EtherCAT
Explanation
A loss of AC power was
detected
IO-Blox communications
error with IO-Blox (#).
The encoder backup bat-
tery is low.
The indicated motor (#)
has been driven hard for
too long a period of time.
The servo system has dis-
abled power to protect
the robot hardware.
The servo system has
detected an electrical or
physical condition that
resulted in an encoder
fault.
An E-STOP condition has
been detected by the
robot.
User Action
Turn high power
back on and restart
the program. If the
error persists, con-
tact your local
OMRON support.
Check user AC
power connections
for shorts or opens.
Turn high power
back on and restart
the program. If the
error persists, con-
tact your local
OMRON support.
Check user IOBlox
connections for
shorts or opens.
Check IOBlox
address switches for
proper con-
figuration. Cycle
power to the control
system. If the error
persists, contact
your local OMRON
support
Replace the encoder
backup battery.
Turn high power
back on; reduce the
speed and/or accel-
eration for the
motion that was in
progress or for
motions that pre-
ceded that motion.
Repeat the motion
that failed.
Write down the fail-
ure message or
code, and look it up
in the eV+ Help.
This is a normal
response to many
E-STOP conditions.
