Selection of feedback mode at time of driving
】
①
Kind of feedback modes at time of driving
Control operation at time of driving of ECK96 type controller can be selected. Control operations of
feedback are following two kinds. However, in case constant amplitude mode is used, it is necessary
to purchase vibration sensor (K-P1398) separately that is an option part, and install.
(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. Amplitude of parts feeder is made
steady by feeding back the vibration sensor signal.
In case of driving under constant amplitude mode, calibration must be implemented in advance. After
the calibration was completed, it moves automatically to constant amplitude mode.
②
Selection method of feedback mode at time of driving
It is automatically selected if calibration is implemented. In case of changing manually, refer to the
following. Before implementing calibration, please confirm that wiring of vibration sensor has been
completed. Moreover, please note that in case the driving was started by selecting constant
amplitude mode without implementing calibration, there is a possibility that normal amplitude may
not be obtained.
【
Manual switching method of feed back mode
】
※
Before switching feedback manually, please confirm that controller is in the stopping state (in case
that the external control terminal is at stop side or panel control, press the STOP key).
If it is difficult
to cut off the external control, please select the panel control [2[ with the driving method selection
[J02] before the following procedure
③
. Then the controller stops.
①
Display the function selection screen long pressing the function key.
J or H is displayed.
②
Select the J function and press the data key.
Any of J00 to J10 is
displayed.
③
Select J05 with the UP/DN key and press the data key. Present set
data (0 for constant voltage mode) is displayed.
④
Select data of mode you want to set with the UP/DN key and press
the DATA key.
(Refer to P.39 for the set value)
⑤
Display returns to J05 and corresponding display lump lights up or
turns off. In case of constant amplitude mode, Vib.A display lamp
lights up.
⑥
Return to the normal screen pressing the function key twice.
