100 Troubleshooting Your Ultra3000 Servo Drive
E10 Bus Overvoltage
Excessive regeneration of power.
When the motor is driven by an external
mechanical power source, it may
regenerate too much peak energy through
the Ultra3000’s power supply. The system
faults to save itself from an overload.
•
Change the deceleration or motion
profile.
•
Use a larger system (motor and
Ultra3000).
•
Use a resistive shunt.
•
If a shunt is connected, verify the wiring
is correct and shunt fuse is not blown.
Excessive ac input voltage. Verify input is within specifications.
E11 Illegal Hall State
Incorrect phasing. Check the Hall phasing.
Bad connections.
•
Verify the Hall wiring.
•
Verify 5V power supply to the encoder.
E12 Home Search Failed
Home sensor and/or marker is outside the
overtravel limits.
•
Check wiring.
•
Reposition the overtravel limits or
sensor.
E13 Home Position In Limit
Home sensor, marker, or final home
position exceeds a hardware overtravel
limit.
•
Reposition the overtravel limits or home
sensor.
•
Adjust the final home position.
E14
SERCOS Hardware Fault
(SERCOS drives only)
A fault was detected with the operation of
the drive’s internal SERCOS hardware. Contact your local Allen-Bradley
representative.
DeviceNet Communications Network
problem (DeviceNet drives only) DeviceNet communications network is
broken
Troubleshoot DeviceNet communications.
E15 Excessive Electrical Cycle Length
Electrical cycle length exceeds maximum
lines per electrical cycle
Replace the linear motor/encoder.
E16
Software Overtravel
(SERCOS only) Programmed overtravel limit has been
exceeded.
•
Verify motion profile.
•
Verify overtravel settings are
appropriate.
E17 User-specified Current Fault
User-specified average current level has
been exceeded.
Increase to a less restrictive setting.
E18 Overspeed Fault
Motor speed has exceeded 125% of
maximum rated speed.
•
Check cables for noise.
•
Check tuning.
E19 Excess Position Error Position error limit was exceeded.
•
Increase the feedforward gain.
•
Increase following error limit or time.
•
Check position loop tuning.
