Noise Control and Measures for Harmonic Suppression
This section describes the wiring for noise control and the DC reactor for harmonic suppression.
3.7.1
Wiring for Noise Control
The SERVOPACK uses microprocessors. Therefore it may receive switching noise from peripheral devices.
To prevent the noise from the SERVOPACK or the peripheral devices from causing a malfunction of any one
of these devices, take the following precautions against noise as required.
• Position the input reference device and noise filter as close to the SERVOPACK as possible.
• Always install a surge absorber in the relay, solenoid and electromagnetic contactor coils.
• Do not bundle or run the main circuit cables together with the I/O signal cables or the linear scale connec-
tion cables in the same duct. Keep the main circuit cables separated from the I/O signal cables and the linear
scale connection cables with a gap of at least 30 cm.
• Do not share the power supply with an electric welder or electrical discharge machine. When the SERVO-
PACK is placed near a high-frequency generator, install a noise filter on the input side of the main circuit
power supply cables and control power supply cables. As for the wiring of noise filter, refer to
shown below.
• Take the grounding measures correctly. As for the grounding, refer to
• Because the SERVOPACK is designed as an industrial device, it provides no mecha-
nism to prevent noise interference.
• The SERVOPACK uses high-speed switching elements in the main circuit. Therefore
peripheral devices may receive switching noise. If the equipment is to be used near
private houses or if radio interference is a problem, take countermeasures against
noise.
• If installation conditions by the EMC directive must be met, refer to
