POSSIBLE CAUSE
Zero or Gain settings for the hall
effect (Film Feed Trigger) are
incorrect.
Maximum speed setting on the
VFD is incorrect.
hall effect device is positioned
incorrectly.
Dancer bar cam is positioned
incorrectly.
hall effect sensor has failed.
Open circuit from the hall effect
device to the analog input card.
Analog I.O. card has failed.
Open circuit from the PLC analog
card to the VFD analog input.
Open circuit from the stretch VFD
to the film feed motor
SOLUTION
Observe the feedback value of the hall
effect located on the touchscreen.
Re-set the ZERO and GAIN values
according to the film feed setup instruc-
tions in the manual. ZERO setting should
be a value of at least ten above the hall
effect feedback value to operate properly.
Review the maximum frequency parame-
ter settings in the VFD. Refer to the sup-
plied VFD Manual for procedure.
Refer to the VFD manual and the Orion
parameter settings sheet supplied with the
machine for maximum frequency settings.
Check to make sure hall effect device is
not touching the dancer bar cam.
Adjust the hall effect-to-cam gap is cor-
rect... approx 16th of an inch gap.
Make sure the cam rotates in such a way
as to create a gap between the hall effect
device and the cam itself.
Adjust the cam correctly.
Check for 24VDC at the sensor. Check for
variable 24VDC on the return wire to PLC
at the sensor.
No variable VDC out? Replace sensor.
Check wire continuity from hall effect
device to the analog input card.
Repair or replace open wiring.
Check the hall effect feedback value on
the MIB screen. If the hall effect value
increases with dancer movement, but the
analog I.O. card toes not fluctuate voltage
out, then the analog I.O. card has failed.
Replace analog I.O card.
Check wire continuity from the PLC ana-
log card output to the VFD analog input.
Repair or replace open wiring.
Check wire continuity from the stretch
VFD outputs to the film feed motor.
Repair or replace open wiring.
