Troubleshooting
9006 Hybrid Control for RollerDrive
The following errors are reported by illuminated LEDs:
(also see "Meaning of the LEDs", page 16)
Symptom Possible cause Help
Motor is in brake mode, red fault
LED flashes once and error output is
active ("No fault output" is active).
Invalid state of motor hall effect
sensor
• Broken wire
• Failed hall effect sensor
Replace the RollerDrive.
Voltage over or under limits
• Power supply fluctuations, failure
or overload condition
Check the power supply.
On a decline, motor is in brake mode
momentarily. Red fault LED flashes
twice ("No fault output" is active) or
power supply shutdown or fuse
blown on card.
Overvoltage detection (caused by
over speed or excessive back EMF)
• decline angle too high
• package weight too high
• Reduce decline angle
• Use brake roller to keep speed low
Motor overrun, overset speed
• Package enters zone at a higher
than anticipated speed
Reduce the package entry speed.
Red fault LED flashes six times and
error output is active ("No fault
output" is active).
Low gain signal from sensor
• Dirty sensor lens or misaligned
Clean the sensor lens and align the
sensor.
Current folds back to maximum
continuous current, amber fault LED
is on.
Card or motor over temperature
• Excessive load or duty cycle
Reduce the load of packages or
throughput of the zone
Current folds back to approximately
1.5 A while applying consistent
torque. Red fault LED is on and error
output is active ("No fault output" is
active).
Motor stall condition
• Obstruction or load too heavy to
be conveyed
Once the stall condition is removed, the
RollerDrive will resume normal
operation.
