N12- G & HW Series Frequency Controllers 115/230VAC
PROBLEM
POSSIBLE REASON
REMEDY
Feeder does not vibrate
Incorrect frequency setting
Resonate frequency search
Feeder hammers when throughput is set high.
• Feeder is working too close to its
resonate frequency.
• Air gap too small.
• Adjust frequency.
• Reduce maximum limit [P]
(Menu “C 096.”).
• Check air gap (Caution: too big an
air gap increases the current).
Magnet gets warm.
• Frequency setting is too low for the
coil type.
• Air gap is too large.
• Adjust to a higher frequency or fit a
more suitable coil.
• Reduce the air gap.
"OFF" displayed and feeder does not run.
• No enable signal.
• Provide enable signal using contacts
of 24.VDC signal.
• Fit a link between enable terminals.
• Or invert parameter “-En”.
After running for a short time the feeder stop and
"Error SE" flashes in the display.
• Sensor time out has been activated,
no material available.
• No track sensor fitted.
• Defective track sensor.
• Cancel sensor time out parameter
“EE”.
• Check sensor.
• Check sensor.
After enabling the feeder or calling from a sensor,
it only runs slowly, even though the soft start is set
at "0". (applies to regulation mode only)
• Maximum limit [P] in Menu “C 008."
or “C 096." has not been set correctly.
• Set the maximum limit to match
the amplitude.
Maximum amplitude is achieved with a very low
throughput setting.
• The mounting position of the sensor
has a small deflection.
• Maximum limit [P] has not been set
for the feeder.
• Reduce maximum limit [P]
(Menu “C096.”).
• Reduce maximum limit [P]
(Menu “C096.”).
ERROR MESSAGE
TYPE OF FAULT
ERROR - OL
Output power too high
Coil power too high.
Controller with a higher power
rating required.
Selected frequency too low.
Increased frequency.
Air gap too large.
Reduce air gap.
Short circuit.
Check circuit and drive coil.
ERROR - OC
Over current
Output short circuit due to
drive coil failure.
Check circuit and drive coil.
ERROR - OU
Over voltage in DC link
Supply voltage too high.
Check mains voltage.
Back emf from drive coil
(possible at lower frequencies).
Control unit may have to be changed for
another type – contact manufacturer.
ERROR - ACC
Sensor fault
Sensor failure.
Defective sensor.
Test sensor.
ERROR - SE
Sensor time out
exceeded
Sensor time out is activated but
not required.
Switch off sensor time out in
Menu “C 16.7”.
The sensor has detected no product.
Check mechanical system.
ERROR - EEP
Memory failure
Component problems.
Contact manufacturer.
