(7) Reset is not effective.
・ There is a signal of the driving
instruction.
Press the reset key after the controller is
stopped (Refer to P.40).
(8) The output voltage
doesn't go up.
・ The limiter by the F-V curve operates.
The setting of the F-V curve is confirmed
(Refer to P.38).
(9) The beat sound is
generated.
・ Plural parts feeders are driven with
driving frequencies that are approximate
with each other.
Separate the driving frequencies by 5Hz or
more, or drive by the same frequency.
Adjustment of a leaf spring may be needed
for some case.
(10) OL blinks immediately.
・ The setting of the current rating is
wrong.
Refer to the paragraph of the setting method
of the function in P.26 and after. Set the
correct current rating.
(11) Driving cannot be
controlled by the
sensor signal.
・ 2~7 is selected by sensor function
selection (H00)
Set the sensor input logic of the function to 0
or 1.
(12)OC lights.
・Short-circuit of the load side.
・ Setting error of controller.
Please check vibration main body and wiring
etc. If there is no abnormality at the load
side, there is a possibility of the controller’s
breakage.
Please check if there is any mistake on
setting of frequency etc.

Measuring method of output voltage
1) As for the measurement of the PWM wave shape, the
instruction value is different according to the
measuring instrument used. Please regard the
indicated value on the controller's operation panel to
be main, and treat the instrument reading as a
reference value.
2) All the measurement ranges are basically "AC", but
there are some equipments which have “DC”
selected. Please examine the setting for the case of
measuring the sine wave PWM wave profile of the
inverter from the instruction manual of the measuring
device or the manufacturer’s document..
3) Please open the panel after turning off the power
supply without fail.
Warning
Be careful that a human body and an
unnecessary object must not touch the
charged part. It causes an electric shock and
a fire.
