1 Method of connecting
EMI/EMC Filter
2 Caution when connecting
EMI/EMC Filter
Please note the excessive temperature increase of EMI/EMC filter.
Please contact us if judgement is difficult.
(1) Input voltage and frequency
Please use within the rated voltage (or maximum voltage) of each
model.
Input frequency specification for AC input EMI/EMC filter is
considered as commercial frequency (50/60Hz).
It should not be used under the following conditions.
1) Distorted input voltage waveform.
(Triangle wave, square wave etc.)
2) High input frequency (ex: 400Hz)
(2) Input current
Please use within the rated current of each model.
EMI/EMC filters have short term peak current capability. Therefore,
it can flow ~40A or ten times of rated current, non-repeated, within a
few ms such as inrush current of power supply etc.
However, it should not be used under the following conditions.
1) Long duration peak current.
2)
Peak current or high-frequency current is continuously flowing.
(3) Connection to a general-purpose inverter (servo driver)
Please connect EMI/EMC filter to input side of inverter driver
(servo driver).
It should not be used between the inverter (servo driver) and the
motor.
