First Checking Item Remedy
●Does the resonant frequency of the partsfeeder match
the driving frequency range of VMC-controller?
●Review the function setting.
●Readjust the resonant frequency of the drive
unit with leaf springs
●Is the setting of the drive frequency range correct?
●Review the function setting.
●Is the weight of a bowl or chute too heavy for the drive
unit?
●Reduce the weight with a decrease of thickness
of a bowl or chute.
●Adjust the air gap.
●Is there any fault wiring, confusing polarities, the
stroke sensor and VMC-controller?
●Is the air gap out of the standard width?
●Review the wiring plug connector.
●Narrow the air gap of the core and armature of
the drive unit.
Trouble Checking Item Turning on Biinking Turning off
A. Feeder does not run
1. Fault wiring of power source
2. Low voltage, supply rated voltage
3. Fuse FU1melts down
B. Feeder does not run
1. Stop by the external operation signal
2. Overflow signal is working.
C. Feeder does not run
1. Fault wiring to the feeder/Cable breaks
2. Fault setting of Stroke
D. Feeder does not run
1. The stroke sensor is not working, removed or broken lead.
2. Stop by over current protection
2-1. Fault wiring to the feeder/Any short circuit
2-2. Drive frequency range is out of the resonant frequency of the drive unit
2-3. The air gap of the drive unit is too wide
E. Stroke does not build up
1. Fault setting of Stroke on the panel
2. Too wide air gap of the drive unit
3. Fault function setting for the Stroke Sensor
4. Feeder provides a bowl out of the specification
F. Stroke fluctuates
1. Fault wiring the shield cable and plug connector
2. Loose fitting of the bowl
G. Memory stores no setting
1. You did not store the data before off the power
