Ultra3000 has a bad IPM
output, short circuit, or
overcurrent,
the continuous power rating.
Increase Motion Time or allow
dwell periods.
Reduce acceleration rates.
Remove all power and motor
connections, and then check
continuity from the DC bus to
U, V, and W outputs. If
continuity exists, check for
conductive materials between
terminals.
Replace the Ultra3000 drive.
6 SERCOS overtravel
ON indicates the SERCOS
Limit indicator is lit.
Dedicated overtravel input is
inactive.
Troubleshoot SERCOS by
checking wiring and verifying
motion profile
7 Encoder channel
line B break ON indicates a wiring error
with channel line B.
Motor wiring error.
Check motor encoder channel
line B wiring.
8 Encoder channel
line A break ON indicates a wiring error
with channel line A.
Motor wiring error.
Check motor encoder channel
line A wiring.
9 Bus Undervoltage
ON indicates the DC Bus is
below normal operating
voltage.
Low AC line/AC power input.
100 VAC minimum for safe
Ultra3000 operation.
Verify voltage level of the DC
Bus. The Bus should be
1.414*VAC level.
Check AC power source for
glitches or line drop.
Install an uninterruptible power
supply (UPS) on your AC
input.
10 Bus Overvoltage
ON indicates the DC Bus is
above 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.
Excessive AC input voltage.
Output short circuit.
Motor cabling wires shorted
together.
Internal motor winding short
circuit. Change the deceleration or
motion profile.
Use a larger system (motor
and Ultra3000).
Use an Active Shunt.
Verify input is below 264 VAC.
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.
Disconnect motor power
cables from the drive. If faults
stop, then either replace cable
or try to find the short.
Verify by disconnecting motor
from drive and then try to turn
