Chapter 3 Configuring the Ultra3000 Drive
10: Bus
Undervoltage ON indicates the DC Bus
is below normal
operating voltage. Excessive regeneration
of power. When the drive
is driven by an external
mechanical power
source, it may
regenerate too much
peak energy through the
drive'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 an Active Shunt.
Excessive AC input
voltage. Verify input is below 264
VAC.
Output short circuit. Disconnect the power
line from the drive and
then do continuity check
from the positive and
negative poles of the DC
Bus to each of the motor
output phases U,V, and
W. If a continuity exists,
check for wire fibers
between terminals, or
send drive in for repair.
Motor cabling wires
shorted together. Disconnect motor power
cables from the drive. If
faults stop, then either
replace cable or try to
find the short.
10: Bus
Overvoltage
(cont.) Internal motor winding
short circuit. Verify by disconnecting
motor from drive and
then try to turn 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. Check the Hall phasing.
Incorrect wiring • 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
communication network
is broken. DeviceNet
communication 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.
