＜Installation direction of vibration sensor＞
As the vibration direction of sensor is predetermined (Arrow mark printed on
sensor is the travel direction of work), please note the installation direction.
When it is not possible to match the direction of arrow mark to the forwarding
direction of work, please install it in the reverse direction and reverse the polarity
with the function J07.
Note) There is a case that it become to reverse direction depending on
vibrator.

Note) Unchangeable functions during driving become changeable at the stopping state of controller (When external control
terminal is at stopping side or panel control, press STOP key). Select panel control [2] with selection J02 of driving method
when it is difficult to cut off the external control. Then controller stops.

５．Adjustment method (Refer to P. 23 and after of operation manual)＜ 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). Itcontrols the constant voltage so that the load (output) voltage becomes thevalue set by the speed adjustment knob.
(B) Constant amplitude mode: Select this mode when the weight variation of work is large or morestable 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 resonancepoint tracking mode, the constant amplitude control also becomes ON atthe same time.
Note) Before adjusting each mode, please confirm that all wirings ended and there is no work in the bowl oron 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.

ＤＡＴＡＥＮＴＥＲ※Points for frequency adjustment
Max. amplitude point (resonance point) of the part feeder is searched lowering thefrequency 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
becomes steady.
