(B) – 1 Driving
*
Gain adjustment is necessary to drive by the constant amplitude mode.
Gain can be automatically adjusted with calibration by the function J05.
Manual gain adjustment is also possible (Refer to P. 30). Please refer to
the following (B)-3 for the calibration method.
When the constant amplitude mode is selected, the display becomes
the % speed display [
○○
P] as written right and the Vib. A lamp lights.
When calibration is done, it is automatically changed to the constant
amplitude mode. In case of manual, it is necessary to select by the
function J05.
①
Control method of driving is the same as for the constant voltage
mode, and it is done by the external control terminal or the
RUN/STOP button on the panel.
②
During stop, LED is blinking, and when driving begins, the % speed
set by the speed adjustment knob is displayed in the lighting state.
Moreover, the RUN pilot lamp also lights.
(B) – 2 Frequency adjustment
①
Please confirm that the F/V curb corresponding to load is selected
(Function J04).
②
Please adjust frequency as same as for the constant voltage mode
(Refer to P. 26).
The behavior becomes steady when driving at a little
higher frequency (3-10Hz).
(B) – 3 Calibration (Gain adjustment)
Implementation method of calibration to drive by constant amplitude mode
①
Please confirm that all wiring, installation of vibration sensor and
frequency adjustment are completed and the controller is at halt condition
(In case the external control terminal is at holt side or panel control, press
the STOP key.). When 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
④
.
Then the controller stops.
②
Display the function selection screen long-pressing the function key.
Either J or H is displayed.
③
Select the J function and press the data key.
Any of J00~ J12 is displayed.
④
Select J05 pressing the UP or DN key, and press the data key.
Present set data is displayed.
⑤
Select the data of 3 with the UP/DN key and press the data key
(3: Calibration for the constant amplitude control).
Display during stop
Display during driving
Display at time when
constant amplitude mode is
selected
