Noise transmission route

Suppression techniques

When measuring instruments, receivers, sensors, etc. which handle weak signals and may malfunction due to noise and/or their signal cables are contained in a control box together with the servo amplifier or run near the servo amplifier, such devices may malfunction due to noises transmitted through the air. The following techniques are required.

1. Provide maximum clearance between easily affected devices and the servo amplifier.

1) 2) 3) 2. Provide maximum clearance between easily affected signal cables and the I/O cables of the servo amplifier.

3.Avoid laying the power lines (Input cables of the servo amplifier) and signal cables side by side or bundling them together.

4.Insert a line noise filter to the I/O cables or a radio noise filter on the input line.

5.Use shielded wires for signal and power cables or put cables in separate metal conduits.

When the power lines and the signal cables are laid side by side or bundled together, magnetic induction noise and static induction noise will be transmitted through the signal cables and malfunction may occur. The following techniques are required.

1. Provide maximum clearance between easily affected devices and the servo amplifier.

4) 5) 6) 2. Provide maximum clearance between easily affected signal cables and the I/O cables of the servo amplifier.

3.Avoid laying the power lines (Input cables of the servo amplifier) and signal cables side by side or bundling them together.

4.Use shielded wires for signal and power cables or put the cables in separate metal conduits. When the power supply of peripheral devices is connected to the power supply of the servo amplifier system, noises produced by the servo amplifier may be transmitted back through the

7)power supply cable and the devices may malfunction. The following techniques are required.

1.Insert the radio noise filter (FR-BIF) on the power cables (Input cables) of the servo amplifier.

2. Insert the line noise filter (FR-BSF01 FR-BLF) on the power cables of the servo amplifier.

When the cables of peripheral devices are connected to the servo amplifier to make a closed loop

8)circuit, leakage current may flow to malfunction the peripheral devices. If so, malfunction may be prevented by disconnecting the grounding cable of the peripheral device.

(2)Noise reduction products

(a)Data line filter

Noise can be prevented by installing a data line filter onto the encoder cable, etc.

For example, the ZCAT3035-1330 of TDK and the ESD-SR-25 of Tokin make are available as data line filters.

As a reference example, the impedance specifications of the ZCAT3035-1330 (TDK) are indicated below.

This impedances are reference values and not guaranteed values.
