by hand. If difficult to turn by
hand, the motor needs to be
repaired or replaced.
11 Illegal Hall State
ON indicates there is a
problem with the motor's
Hall Effect sensors.
Incorrect phasing
Bad connections
Check the Hall phasing.
Verify the Hall wiring.
Verify power supply to
encoder.
12 Home Search Failed
ON indicates that the home
position was not found.
Home sensor or marker is
outside the overtravel limit.
Check wiring
Reposition the overtravel limits
or home sensor.
13 Home Position Outside
Limits ON indicates that the home
position exceeds a
hardware overtravel limit
value.
Home sensor, marker or final
home position exceeds a
hardware overtravel limit.
Reposition the overtravel limits
or home sensor.
Adjust the final home position.
14 Net communication
ON indicates DeviceNet
communications network is
broken.
DeviceNet communications
network is broken.
Troubleshoot DeviceNet.
15 Electrical Cycle
(For linear motors only) ON
indicates there is a problem
with the motor's maximum
line count.
Electrical cycle length exceeds
maximum lines per electrical
cycle.
Replace the linear
motor/encoder.
16 SERCOS Overtravel
ON indicates SERCOS
overtravel limit exceeded.
Programmed overtravel limit
has been exceeded.
Verify motion profile.
Verify overtravel settings are
appropriate.
17 User Current
ON indicates the User
Current Fault level, input
above, has been exceeded.
User-specified average
current level exceeded. Increase User Current Level
and Time to a less restrictive
setting.
Increase time allowed for
motion
18 Overspeed
ON indicates the motor
speed has exceeded 125%
of maximum rated speed.
Motor exceeded 125% of the-
specified maximum rated
speed. Check cables for noise.
Check Motor wiring.
Retune drive & motor
combination.
Use an actual oscilloscope to
check Encoder phasing.
19 Following Error
ON indicates the Following
Error Limit, set above, has
been exceeded.
Position error limit exceeded.
Retune the drive, start by
setting the feedforward gain to
100%.
Increase the Following Error
Limit and Time.
If in Follower Mode, increase
the Slew Limit (in the Follower
window).
Check position loop tuning.
20 Motor Encoder State
ON indicates the motor
encoder encountered an
illegal transition.
Motor encoder encountered
an illegal transition
Replace the motor/encoder.
Use shielded cables with
twisted pair wires.
Route the feedback away from
potential noise sources.
Check the system grounds.
Ensure digital filtering of
encoder signals is enabled.
