・
Gain adjustment was not done well.
Perform calibration again or adjust the gain by
hand. Refer to P.28~P.30.
・
Frequency is not properly adjusted.
Adjust frequency. Refer to P.26.
(16)Even if the speed
adjustment knob was
fully turned, amplitude
is insufficient..
・
Leaf spring is fatigued or broken.
Please check the leaf spring of the vibration
main body, then adjust the frequency.
・
Short-circuit of the load side.
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.
(17)
OC lights.
・
Setting error of controller.
Check if there is any mistake in setting of
frequency and current rating 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) Measurement range is “AC” in principle. However, for
the actual measurement, please check “For the case
of measuring the sign wave PWM wave pattern of
inverter output” in the instruction manual of the
measuring device or document of the manufacturer.
3) Please open the terminal cover 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.
