E16
Softovertravel Fault
(+/- Software Overtravel)
Axis position exceeded maximum software setting.
• Verify motion profile.
• Verify overtravel settings are
appropriate.
E18
OverSpeedFault
(Overspeed Fault)
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.
• Check cables for noise.
• Check tuning.
E19
PositionErrorFault
(Follow Error)
Position error limit was exceeded.
• 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.
E20
MotFeedbackFault
(Mtr Fdbk AQB)
Motor Encoder State
Error The motor encoder encountered an
illegal transition.
• Use shielded cables with twisted pair
wires.
• Route the feedback away from potential
noise sources.
• Check the system grounds.
• Replace the motor/encoder.
E21
AuxFeedbackFault
(Aux Feedback Comm)
Communication was not established with an intelligent encoder. Verify auxiliary encoder wiring.
E30
MotFeedbackFault
(Motor Feedback Comm)
Communication was not established with an intelligent encoder.
• Verify motor selection.
• Verify the motor supports automatic
identification.
• Verify motor encoder wiring.
E34
GroundShortFault
(Ground Fault)
Excessive ground current
in the converter was
detected.
Wiring error.
• Check motor power wiring.
• Check input power wiring.
Motor internal ground short. Replace motor.
Internal malfunction.
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.
Grounded control power terminal
(applies to 230V systems only)
• Remove ground from control power
input.
• Source control power from three-phase
input power (refer to page 204).
• Add isolation transformer for control
power.
E35
DriveUndervoltage
Fault
(Pre-charge Fault)
Converter pre-charge
cycle failed.
Low AC input voltage. Check input AC voltage on all phases.
Internal malfunction. Call your sales representative.
E36
DriveOvertemp Fault
(System Overtemperature)
Converter thermal switch
tripped. Excessive heat exists in the power
circuitry.
• Reduce acceleration rates.
• Reduce duty cycle (ON/OFF) of
commanded motion.
• Increase time permitted for motion.
• Use larger IAM converter module.
• Check for clogged vents or defective
fan.
• Make sure cooling is not restricted by
insufficient space around the unit.
