Troubleshooting Your Ultra3000 Servo Drive 99
E02 Velocity Exceeds Position Rollover /2
The velocity command or feedback exceeds
half the machine cycle length per
millisecond (applies only when the
machine cycle position rollover is enabled).
Increase machine cycle size or reduce
velocity profile.
E03 Absolute Feedback Range Exceeded
The motor position exceeds +/- 2047
revolutions from the home position (applies
only to systems with absolute feedback).
•
Decrease application range of motion.
•
Upgrade firmware.
This error only applies to firmware versions
prior to 1.10.
E04 Motor Overtemperature
Motor thermostat trips due to:
•
High motor ambient temperature
and/or
•
Excessive current
•
Operate within (not above) the
continuous torque rating for the
ambient temperature (40°C maximum).
•
Lower ambient temperature, increase
motor cooling.
Motor wiring error. Check motor wiring.
Incorrect motor selection. Verify the proper motor has been selected.
E05 IPM Fault
Motor cables shorted.
Verify continuity of motor power cable and
connector.
Motor winding shorted internally.
Disconnect motor power cables from the
motor. If the motor is difficult to turn by
hand, it may need to be replaced.
Ultra3000 temperature too high.
•
Check for clogged vents or defective
fan.
•
Ensure cooling is not restricted by
insufficient space around the unit.
Operation above continuous power rating.
•
Verify ambient temperature is not too
high.
•
Operate within the continuous power
rating.
•
Reduce acceleration rates.
Ultra3000 has a bad IPM output, short
circuit, or overcurrent.
Remove all power and motor connections,
and preform a continuity check from the dc
bus to the U, V, and W motor outputs. If a
continuity exists, check for wire fibers
between terminals, or send drive in for
repair.
An attempt was made to enable the drive
without waiting at least 1.0 second after
applying the main ac power. Note: This
only applies to Ultra3000 models
2098-DSD-005, 2098-DSD-010, and
2098-DSD-020 (when using an external
+5V auxiliary power supply).
Wait at least 1.0 second after the main ac
is applied before enabling the drive.
E06
Hardware Overtravel
(SERCOS only)
Dedicated overtravel input is inactive.
•
Check wiring.
•
Verify motion profile.
E07 RESERVED
Call your local Allen-Bradley
representative.
E08 RESERVED
E09 Bus Undervoltage Low ac line/ac power input.
•
Verify voltage level of the incoming ac
power.
•
Check ac power source for glitches or
line drop.
•
Install an uninterruptible power supply
(UPS) on your ac input.
