＜Kind of feedback modes at time of driving＞
Feedback control operations at time of driving of K-ECG25 are following three kinds:
(A) Constant voltage mode:
This is a mode generally used (Initial setting at the time of shipment). It
controls the constant voltage so that the load (output) voltage becomes the
value set by the speed adjustment knob.
(B) Constant amplitude mode: Select this mode when the weight variation of work is large or more
stable feeding operation is required.
(C) Resonance point tracking mode: To drive more efficiently, this controls so that the amplitude
becomes steady at the resonance point of parts feeder. In the resonance
point tracking mode, the constant amplitude control also becomes ON at
the same time.
Note) Before adjusting each mode, please confirm that all wirings ended and there is no work in the bowl or
on the chute, and then set functions of J01 and J04. Moreover, before adjusting the constant amplitude
mode and resonance point tracking mode, please install vibration sensor and set function J06 and J07
with the resonance point tracking mode.
（Ａ）Adjustment method of constant voltage mode (Refer to P. 26 of operation manual)
（Ｂ）Adjustment method of constant amplitude mode (Refer to P. 28 of operation manual)
（Ｃ）Adjustment method of resonance point tracking mode (Refer to P. 31 of operation manual)
Refer to operation manual for details of driving and adjustment.
６．Trouble shooting
In the event that any trouble occurs, please refer to P. 54 to 56 of operation manual.

※Points for frequency adjustment
Max. amplitude point (resonance point) of the part feeder is searched lowering the
frequency from the initial value (ECG25:140Hz,ECJ45:70Hz）gradually with the down key.
After that, drive by
frequency (3~10Hz) slightly higher than resonance point. Then vibration
