Chapter 4 Configuring the Ultra5000 Drive
20: Motor
Encoder State ON indicates the motor
encoder encountered an
illegal transition. 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 Ultra5000
and motor.
23: Thermal
Protect Filter ON indicates the internal
filter protecting the drive
from overheating has
tripped. Drive overheated • Reduce acceleration
rates.
• Reduce duty cycle
(ON/OFF) of
commanded motion.
• Increase time
permitted for motion.
• Check system tuning.
• Use larger Ultra5000
and motor.
Operation above
continuous power rating. • Verify ambient
temperature is not too
high. Operate within
the continuous power
rating.
• Increase Motion Time
or dwell periods.
24: Velocity Error ON indicates that the
velocity error exceeds
the Velocity Error Fault
Limit for a length of time
greater than the Velocity
Error Fault Time value. Velocity error limit
exceeded. • Increase Velocity Error
Fault Limit or Velocity
Error Fault Time value
or both.
• Reduce Acceleration.
• Retune the drive.
