Generated noise of drive system
Noise propagation path
Measures
[1] [2] [3]
When devices such as instrument, receiver or sensor, which handle minute signals and
are easily affected by noise, or the signal wire of these devices, are stored in the same
panel as the drive units and the wiring is close, the device could malfunction due to
airborne propagation of the noise. In this case, take the following measures.
(a) Install devices easily affected as far away from the drive units as possible.
(b) Lay devices easily affected as far away from the signal wire of the drive unit as
possible.
(c) Avoid laying the signal wire and power line in a parallel or bundled state.
(d) Insert a line noise filter on the input/output wire or a radio filter on the input to
suppress the noise radiated from the wires.
(e) Use a shield wire for the signal wire and power line, or place in separate metal ducts.
[4] [5] [6]
If the signal wire is laid in parallel to the power line, or if it is bundled with the power line,
the noise could be propagated to the signal wire and cause malfunction because of the
magnetic induction noise or static induction noise. In this case, take the following
measures.
(a) Install devices easily affected as far away from the drive unit as possible.
(b) Lay devices easily affected as far away from the signal wire of the drive unit as
possible.
(c) Avoid laying the signal wire and power line in a parallel or bundled state.
(d) Use a shield wire for the signal wire and power line, or place in separate metal ducts.
[7]
If the power supply for the peripheral devices is connected to the power supply in the
same system as the drive units, the noise generated from the power supply unit could
back flow over the power line and cause the devices to malfunction. In this case, take
the following measures.
(a) Install a radio filter on the power supply unit's power line.
(b) Install a power filter on the power supply unit's power line.
[8]
If a closed loop is created by the peripheral device and drive unit's grounding wire, a
leakage current could flow and cause the device to malfunction.
In this case, change the device grounding methods and the grounding place.
