有效电机电缆屏蔽
电缆屏蔽有效性的一般规则是：越好
屏蔽越紧，辐射发射水平越低。这个
下图显示了一个有效构造的示例（例如
例如Ölflex伺服FD 780 CP、Lapp Kabel或MCCMK，
Draka-NK电缆）。
将电缆屏蔽夹在驱动端的压盖板中，扭转
电缆将导线屏蔽在一起，形成一束（引线），不再长
并将其连接到标记的端子

•控制电缆必须为屏蔽双绞线型。
•屏蔽必须拧成一束（引线），而不是
长度大于其宽度的五倍，并连接到端子
X1:1（用于数字和模拟输入/输出电缆）。为了连接所述网络
RS485电缆的屏蔽线，请参阅说明（和
注3）142页。
布线控制电缆以尽量减少对电缆的辐射：
•线路尽可能远离输入电源，以及
电机电缆（至少20厘米[8英寸]）。
•如果控制电缆必须穿过电力电缆，请确保：
它们的角度尽可能接近90°，以小化
干扰
•与驱动器侧面保持至少20厘米（8英寸）的距离。
•将继电器控制的信号作为双绞线运行（特别是在以下情况下：
电压＞30V）。继电器控制的信号使用少于
30V可以在与数字输入信号相同的电缆中运行。

Keep individual unshielded wires between the cable clamps and the screw terminals as short as possible. Route control cables away from power cables. Input power (mains) cables See sections Input power (mains) cable, fuses and circuit breakers on page 401 and Input power (mains) cable on page 406. Motor cables See section Motor connection on page 410 for the maximum motor cable lengths meeting the IEC/EN 61800-3 requirements for category C2 or C3, as applicable. The figure below shows the minimum requirements for the motor cable shield. Galvanised steel or tinned copper wire with braided shield. Layer of copper tape with concentric layer of copper wire. Concentric layer of copper wire. Preparing for installation 29 ACH550-01 User's Manual The figure below shows non-recommended motor cable types. Figures courtesy of Draka NK Cables. Copyright © 2003 Draka NK Cables. The figure below shows the recommended conductor layout. Symmetrical shielded cable: threephase conductors and a concentric or otherwise symmetrically constructed PE conductor, and a shield Recommended (CE & C-Tick) PE conductor and shield A separate PE conductor is required if the conductivity of the cable shield is < 50% of the conductivity of the phase conductor. Not allowed for motor cables (CE & C-Tick) Shield PE PE Allowed for motor cables with phase conductor cross section up to 10 mm2. A four-conductor system: three-phase conductors and a protective conductor, without a shield. Allowed (CE & C-Tick) Shield Shield 30 Preparing for installation ACH550-01 User's Manual Effective motor cable shields The general rule for cable shield effectiveness is: the better and tighter the shield, the lower the radiated emission level. The figure below shows an example of an effective construction (for example Ölflex-Servo-FD 780 CP, Lapp Kabel or MCCMK, Draka NK Cables). Clamp the cable shield into the gland plate at the drive end, twist the cable shield wires together into a bundle (pigtail) not longer than five times its width and connect it to the terminal marked (at the bottom right-hand corner of the drive) if you are using a cable without a separate PE conductor. Insulation jacket Braided metallic shield Inner insulator L1 L2 L3 Preparing for installation 31 ACH550-01 User's Manual The figure below shows the grounding principles of cables. At the motor end, the motor cable shield must be grounded 360 degrees with an EMC cable gland, or the shield wires must be twisted together into a bundle (pigtail) not longer than five times its width and connected to the PE terminal of the motor. The same principle applies to cabinet installations. wires as possible covered with conductive tape As short unshielded wires as possible SUPPLY CABLE MOTOR CABLE Short pigtail Cable shielding covered with conductive tape Unpainted gland plate EMC cable gland Clamping nut Continuity of Cable Faraday cage Conductive shielding and compression seal 32 Preparing for installation ACH550-01 User's Manual Control cables General recommendation Use shielded cables, temperature rated at 60 °C (140 °F) or above. The figure below shows examples of recommended cables. Figures courtesy of Draka NK Cables. Copyright © 2003 Draka NK Cables. • Control cables must be shielded and of twisted pair type. • The shield must be twisted together into a bundle (pigtail) not longer than five times its width and connected to terminal X1:1 (for digital and analogue I/O cables). For connecting the shield wires of the RS485 cable, see the instructions (and note 3) on page 142. Route control cables to minimise radiation to the cable: • Route as far away as possible from the input power and motor cables (at least 20 cm [8 in]). • Where control cables must cross power cables make sure they are at an angle as near to 90° as possible to minimise interference. • Keep at least 20 cm (8 in) away from the sides of the drive. • Run relay-controlled signals as twisted pairs (especially if voltage > 30 V). Relay-controlled signals using less than 30 V can be run in the same cables as digital input signals.
