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 system (motor and Kinetix 6000
drive).
• Install shunt module.
Verify input is within specifications.
• Verify the Hall wiring at the MF connector on
the IAM/AM module.
• 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 wiring.
• Verify motor selection.
• Verify the motor supports automatic
identification.
• Verify motor encoder wiring.
Make sure there is no motor shaft movement
during power up, Sercos ring phase-up, or during a
fault reset.
• Check motor power wiring.
• Check input power wiring.
Replace motor.
Disconnect motor power cable from drive and
enable drive with current limit set to 0. If fault
clears, then a wiring error or motor internal
anomaly exists. If fault remains, call your sales
representative.
• Remove ground from control power input.
• Source control power from three-phase input
power (refer to diagram on page 192).
