Problem or Symptom
With three-phase power
present, the dc bus volt-
age is below its limit
DC bus voltage fell
below the undervoltage
limit while an axis on the
follower power rail was
enabled
The dc bus voltage is
above its limit
State of Hall feedback
inputs is incorrect
Axis position exceeded maximum software setting. •
Motor speed has exceeded 150% of maximum
rated speed. The 100% trip point is dictated by the
lesser of the user velocity limits or the motor rated
base speed.
Position error limit was exceeded.
Motor Encoder State
Error
Communication was not established with an intelli-
gent encoder.
Communication was not established with an intelli-
gent encoder.
Potential Cause
DC bus voltage for 230V
system is below 137V
Excessive regeneration
of power. When the
motor is driven by an
external mechanical
power source, it may
regenerate too much
peak energy through the
drive power supply. The
system faults to save
itself from an overload.
DC bus voltage for 230V
system is over 410V
Bad connections.
The motor encoder
encountered an illegal
transition.
Possible Resolution
•
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.
Disable follower axis before
removing power.
•
Change the deceleration or
motion profile. • Use a larger sys-
tem (motor and Kinetix 2000
drive). • Install shunt module.
Verify input is within specifica-
tions.
•
Verify the Hall wiring at the MF
connector on the IAM/AM.
• Verify 5V power supply to the
encoder.
Verify motion profile.
• Verify overtravel settings are
appropriate.
•
Check cables for noise.
• Check tuning.
•
Increase the feed forward gain.
• Increase following error limit or
time.
• Check position loop tuning.
• Verify sizing of system.
• Verify mechanical integrity of
system within specification limits.
•
Use shielded cables with
twisted pair wires.
• Route the feedback away from
potential noise sources.
• Check the system grounds.
• Replace the motor/encoder.
Verify auxiliary encoder wir-
ing.
•
Verify motor selection.
• Verify the motor supports auto-
matic identification.
• Verify motor encoder wiring.
