13 Troubleshooting
If the drive does not function as expected, check the following parameters:
•
Input voltage within drive and motor range.
•
Motor and I/O connections are wired correctly to the drive.
•
Verify the configuration parameters were written into the drive successfully.
The table given in section 13.1 and 13.2 details the status LED flash codes and suggested recovery
steps.
13.1 Status LED (Red)
Flash Code Description
Possible cause
Result
Recovery method
ON
(Steady)
Drive
hardware or
Software
error.
Processor is
inoperable.
•
Processor fault.
Drive
outputs are
disabled.
•
Disconnect power from the
drive for 30 seconds for drive
to reset and internal
components to discharge.
Then re-apply power to drive.
OFF
No Errors /
Faults.
•
Drive is operational.
Drive is
operational
.
•
Use the ‘Enable’ input to
enable or disable the drive
outputs.
Flicker
(fast blinking)
Invalid
configuration.
•
Drive has not been
configured.
Drive
outputs are
disabled.
•
Use configuration software to
write a valid configuration into
the drive.
1
Over Current
•
Output current was detected
as too high.
Drive
outputs are
disabled.
•
Check motor wires for shorts.
•
Verify current loop tuning for
stable operation.
2
Voltage Fault
or Shunt
Overpower
•
Drive power is above/below
operational limits.
•
Braking resistor is turned ON
for more than 3 seconds.
•
No Braking resistor available
in the circuit or the resistor is
too small for the energy
dissipated.
•
Braking resistor turn
ON/OFF limits are set too
low.
Drive
outputs are
disabled.
•
Verify voltage of power supply.
•
Verify braking resistor is
properly sized and installed.
•
Verify braking resistor turn
On/Off levels are above the
power supply input voltage.
3
Motor
Feedback
Fault
•
Hall / Commutation signal
Fault.
•
Encoder Fault.
•
Incorrect Hall and Encoder
parameters entered in the
software.
Drive
outputs are
disabled.
•
Verify hall / commutation
signals are present and
working correctly.
•
Verify encoder signals are
present and working correctly.
•
Verify Motor Pole Pairs, Hall
sensor configuration and
Encoder resolution/options.
4
System Fault
•
Drive Over Temperature
•
Motor Over Temperature
•
Motor Over Speed
•
Motor Control Error
Drive
outputs are
disabled.
•
Verify temperature of drive or
motor.
•
Check for overload conditions.
•
Check for mechanical
conditions that would cause an
over speed condition.
Note: Detailed status information can be obtained using the drive configuration software.
