Configuring the Ultra3000 Drive Chapter 3
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 the time
period for motion to
occur.
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,
starts by setting the
feed forward gain to
100%.
Increase the Following
Error Limit, above.
If in Follower Mode,
increase the Slew
Limit (in the Follower
window).
20: Motor
Encoder State
ON indicates the motor
encoder encountered an
illegal transition.
² 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.
21: Auxiliary
Encoder State
ON indicates the
auxiliary encoder
encountered an illegal
transition.
Auxiliary encoder
encountered an illegal
transition
Use shielded cables
with twisted pair
wires.
Route the encoder
cable away from
potential noise
sources.
Bad encoder - replace
encoder.
Check the ground
connections.
Set a time violation
interval on a Step/
Direction or CW/CCW
input command.
Check input timing to
determine if the auxiliary
encoder timing
requirements are met.
22: Motor Filter ON indicates the internal
filter protecting the
motor from overheating
has tripped.
Motor overheated Reduce acceleration
rates.
Reduce duty cycle
(ON/OFF) of
commanded motion.
Increase time
permitted for motion.
Check system tuning.
Use larger Ultra3000
and motor.
