Troubleshooting Chapter 7
FLT S10 – INV OVERCURRENT Inverter Overcurrent Fault Inverter current has exceeded the
instantaneous current limit (determined by
hardware). • Check motor power cable for shorts.
• Verify motor windings are not shorted.
• Verify motor power wire gauge.
• Operate within the continuous power
rating.
• Reduce acceleration times.
FLT S11 – INV OVERTEMP FL Inverter Overtemperature Factory Limit
Fault The measured inverter temperature has
exceeded the factory set temperature limit. • Modify the command profile to reduce
speed or increase time.
• Reduce drive ambient temperature.
• Verify airflow through drive is not
obstructed.
FLT S13 – INV OVERLOAD FL Inverter Thermal Overload Factory Limit
Fault The thermal model for the power transistors
indicates that the temperature has exceeded
the factory set thermal capacity rating of
110%. Modify the command profile to reduce speed
or increase time.
FLT S16 – GROUND CURRENT Ground Current Factory Limit Fault The sensing circuitry in the power stage has
detected excessive ground current. • Check motor power wiring; check power
cable for shorts.
• Replace motor if the fault persists.
FLT S23 – AC PHASE LOSS AC Single Phase Loss Fault A single AC input phase was lost while the
drive was enabled. Check AC input voltage on all phases.
FLT S25 – PRECHARGE FAILURE Pre-charge Failure Fault The pre-charge circuit monitoring algorithm
detected that the DC bus did not reach a
factory set voltage level after charging for a
period of time. • Check AC input voltage on all phases.
• Check input power wiring.
• Replace drive if fault persists.
FLT S29 – BUS OVERLOAD FL Bus Regulator Thermal Overload Factory
Limit Fault The shunt thermal model has exceeded its
factory set thermal capacity limit. • Modify the duty cycle of the application.
• Add external shunt for additional
capacity.
• Add capacitor module if needed.
FLT S34 – BUS UNDERVOLT UL Bus Undervoltage User Limit Fault DC Bus voltage level is below the user set
limit as given by Bus Undervoltage User
Limit. • Verify voltage level of the incoming AC.
• Monitor AC power source for glitches or
line droop.
• Install UPS on AC input.
• Decrease Bus Undervoltage UL attribute
value.
FLT S35 – BUS OVERVOLT FL Bus Overvoltage Factory Limit Fault DC Bus voltage level is above the factory set
limit as determined by the configured input
voltage. • Change the deceleration or motion
profile of all drives connected to the DC
bus.
• Unplug the shunt connector and measure
the resistance of the shunt.
• Replace drive if shunt resistor is open.
FLT S37 – BUS POWER LOSS Bus Power Loss DC Bus voltage level is below the Bus Power
Loss Threshold for more than the timeout
period specified Bus Power Loss Time value. • Verify voltage level of the incoming AC.
• Monitor AC power source for glitches or
line droop.
• Install UPS on AC input.
FLT S41 – FDBK SIGNAL NOISE FL Feedback Signal Noise Fault Noise induced A/B channel state changes
(illegal states) from a feedback device were
detected by the drive. Specifically, the
number of these noise events that have
occurred on this channel has exceeded the
Feedback Noise Factory Limit. The offending
feedback channel number is encoded in the
associated Fault/Alarm Sub Code. • Check motor feedback cable and
connector.
• Cycle power.
• Check feedback shield connection.
• Reduce shock and vibration to motor.
• Replace motor if fault continues.
FLT S45 – FDBK COMM FL Motor Feedback Data Loss Factory Limit
Fault The number of consecutive missed or
corrupted serial data packets from the
intelligent feedback device has exceeded a
factory set limit. • Check motor feedback cable and
connector.
• Check motor power cable and feedback
wire shields are secured correctly.
• Check motor frame is grounded correctly.
FLT S50 – HARDWARE OVERTRAVEL POSITIVE Hardware Overtravel Positive Axis moved beyond the physical travel limits
in the positive direction and activated the
Negative Overtravel limit switch. • Check wiring.
• Verify motion profile.
• Verify axis configuration in software.
FLT S51 – HARDWARE OVERTRAVEL
NEGATIVE Hardware Overtravel Negative Axis moved beyond the physical travel limits
in the negative direction and activated the
Negative Overtravel limit switch. • Check wiring.
• Verify motion profile.
• Verify axis configuration in software.
