Electronic control equipment has different operating characteristics from electromechanical equipment. Safety
instructions for the application, installation and maintenance of the electronic control unit, important differences
between the electrical and electronic control unit and the electric machine, and contents of the use for the
electric control unit. Due to these differences and the various uses of electronic equipment, the person
responsible for the application of this equipment must use and install this equipment only within the permitted
scope of application.
Overview of electrical noise control
Electrical noise can be caused by normal operation of components or components of the system due to
voltage spikes. The conduction mechanism may interfere with the operation of parts or elements of other
systems (noise interference), resulting in malfunction.
Generate noise source
1. Mechanically switched inductive loads generate strong noise intermittently. (MC, MCCB, etc.)
2. PWM drive power output generates severe continuous noise.
3. Switch mode DC power supply (SMPS) may continue to generate noise.
4. Noise source may occur due to contact switching.
Among the causes of the above noise sources, the noise that the system manufacturer can reduce is only
the contact switching noise.
Conduction noise
Electrical noise interferes with the normal operation of the equipment. In the case of electrical noise
conduction, noise may be directly conducted by the system power wiring, and may be emitted to the outside
through the wiring of the industrial control device (inverter).
ACㆍDC power cable installation
For AC·DC power installation, it is recommended to use junction, isolation, shielding and filter for power
supply and related wiring.
Motor power cable installation
If possible, do not extend the motor power cable. In principle, the cable between the drive and the motor can
not be used in extended connection. The universal reason for changing (extending) cables in the middle is
for applications that require flexible cables. Observe the following guidelines when handling the remaining
cables.
1. Do not detect different types of cables together. A transformer which is valid in HF is formed.
2. Cable length should be cut to fit the application.
3. If you can not cut the remaining cable, please arrange it in '8' or 'S' form. Never roll it round.

Cable shield treatment
The cables that require shielding are those that are driven by the inverter and special motors. We
recommend using a shielded cable as shown in the figure below where there is a lot of noise or precise
signal is required.
Precautions
Prepare for shielding Shield electrical wiring
Duct section separation
You should classify it as noise sources and noise interference rather than using convenience or clean wiring
as a reference. Regarding Noise of Cable Wiring Noise is judged to be a color line as ducts of a wiring which
is judged to be a clean signal line by using a "gray" line duct and ducts of a noise generating wiring by using
a duct of a "black" line This helps the wiring technician to isolate and manage the cables correctly.
Isolation work for panel cable noise
1. It is possible to install close to the line where the noise is generated and the line where the noise is
generated by placing a plated steel barrier.
2. If you need a lot of noisy power in area A, it is recommended to use shield cable through area B line.
3. As in the case of a cable consisting of A-zone horizontal line, it is necessary to avoid loops because
loops are formed centering on control microcomputer (loops cause high frequency of RF characteristic).
4. There must be no ground potential difference between the distributor panel and the main panel.
Connecting as much wire as possible helps to bring the ground potential close to 0V)
5. If possible, ground the shield at the panel entrance, as data and communication cables may contain noise
in the shield. Also, the data / communication cable and the power cable must be isolated and installed.

Isolation operation for cable noise
Isolation operation for cable noiseThe wiring of the microcomputer input / output wiring and the AC input
terminal must be separated from each other to prevent noise from occurring.
Precautions
The noise filter of the AC input terminal of the microcomputer must be separated from the input / output wiring
of the noise filter (the noise filter function is seriously degraded when integrated wiring is installed), and the
output terminal should be connected to the nearest position to the microcomputer.
Contact noise suppression method
MC's contactor coil, relay coil, transformer circuit, solenoid coil, cabinet Fluorescent lamp, etc. can be reduced
by applying a noise suppressing capacitor. Contact noise for an AC circuit controlled by a switch such as a
contactor coil or a relay coil requires an RC suppressor circuit at either the coil's positive or negative terminal
or an equivalent snubber capacitor. Generally 100Ωand 0.1Uf are connected in series, but it needs to be
adjusted according to the load power.
How to Identify the Source of the Noise Source
This is an oscilloscope-based measurement of noise peak inductance, as a method of directly measuring
noise in the field.
1. Induced peaks are short and the amplitude varies greatly with time, which is often difficult to measure.
2. On the oscilloscope, set the time axis to 1us /div and set the trigger to capture the peak.
3. Slowly increase the trigger level until triggering stops to measure the maximum peak voltage displayed.
4. Connect the probe grounding clip of the oscilloscope to the probe tip to form a small loop.
5. In the indirect measurement of the cable, the loop probe antenna is sensitive to the direction, so you
must measure the position by capturing the maximum value and fixing the probe.
