产品细节介绍
140AVI03000模拟量输入模块
斩波器控制上有启用输入和继电器输出板输入可以连接到温度敏感开关安装在电阻器组件中，以保护电阻器免受过热（详见第4章-电气安装信息）。继电器输出指示斩波器故障。斩波器可以通过外部控制位置控制光纤链路。使用链接可以同步多个制动斩波器。在标准应用中，光纤链路不是习惯于附件强烈建议为ACS 600配备主接触器由斩波继电器输出控制。此配置还需要用于系统启动的手动启动/停止开关。有关更多信息，参见第4章-电气安装。
交货检查该包装包含：•制动斩波器类型NBRA-6xx（根据表2-1检查正确类型）
•NBRA-6xx安装和启动指南（本文件）。
保修请参阅随频率提供的安装和启动手册
转换器以获取保修信息。制动电阻器每个ACS 600/NBRA-6xx都有标准电阻器
结合体表2-1中规定了这些电阻器附录A中给出的尺寸（一些组合需要使用两个并联电阻。）具有电阻的其他电阻器也可以使用不低于最小允许电阻值（R）的电阻。
警告！切勿使用电阻值低于此值的制动电阻器该特定规定的最小允许电阻值ACS 600/制动斩波器组合。切碎器和变频器无法处理低电阻。
如果标准制动电阻器的散热能力（ER）为不足以应用，可以使用四个电阻器两个标准电阻器并联的组件两个串联。此实施不会改变总阻力电阻器组件。
保险丝NBRA-658、NBRA-659和NBRA-669需要使用制动电路保险丝。
如果出现以下所有情况，则其他装置不需要保险丝满足规定：
•ACS 600电源电缆由保险丝保护
•电缆和熔断器为特定类型安装和启动手册中的变频器型号
•制动斩波器电路电缆符合本指南的规定。
制动电路中的保险丝保护斩波器和制动电缆短路情况下的电路电缆。
保险丝不起保护作用防止电缆、斩波器或电阻器过载。
超载可通过接线的温度传感器实现保护电阻器连接至斩波器的启用输入，同时将斩波器的继电器输出连接到主接触器ACS 600的控制电路。
保险丝必须安装在尽可能靠近ACS 600的地方中间电路端子（UDC+和UDC-）。
无保护电缆长度不得超过0.5米。
There is an enable input
and a relay output on the chopper control board. The input can be connected to a temperature sensitive switch mounted in the resistor assembly to protect the resistor against overtemperature (see Chapter 4 – Electrical Installation for more information). The relay output indicates chopper faults. The chopper can be controlled from an external control location via a fibre optic link. Using the link it is possible to synchronise several braking choppers. In standard applications the fibre optic link is not used. Accessories It is highly recommended to equip the ACS 600 with a main contactor controlled by the chopper relay output. This configuration also requires a manual start/stop switch for system start-up. For more information, see Chapter 4 – Electrical Installation. Delivery Check The package contains: • Braking chopper type NBRA-6xx (check the correct type with Table 2-1) • Installation and Start-up Guide for NBRA-6xx (this document). Warranty See the Installation and Start-up Manual delivered with the frequency converter for warranty information.
Braking Resistors
Standard resistors are available for each ACS 600 / NBRA-6xx combination. These resistors are specified in Table 2-1, and their dimensions given in Appendix A. (Some combinations require the use of two parallel-connected resistors.) Other resistors with a resistance not below the minimum allowed resistance value (R) may also be used. WARNING! Never use a braking resistor with a resistance value below the minimum allowed resistance value specified for that particular ACS 600 / braking chopper combination. The chopper and the frequency converter are not able to handle the overcurrent caused by the low resistance. If the heat dissipation capacity (ER) of the standard braking resistor is not sufficient for the application, it is possible to use a four resistor assembly in which two standard resistors are connected in parallel and two in series. This implementation does not change the total resistance of the resistor assembly. Fuses The NBRA-658, NBRA-659 and NBRA-669 require the use of braking circuit fuses. Other units do not require the fuses if all of the following provisions are fulfilled: • the ACS 600 mains cable is protected with fuses • the cable and the fuses are of the type specified for that particular converter model in its Installation and Start-up Manual • the braking chopper circuit cables are as specified in this Guide.
The fuses in the braking circuit protect
the chopper and the braking circuit cables in a cable short-circuit situation. The fuses do not protect the cables, the chopper or the resistor against overload. Overload protection can be implemented by wiring the temperature sensor of the resistor to the Enable Input of the chopper and simultaneously connecting the Relay Output of the chopper to the main contactor control circuit of the ACS 600. The fuses must be installed as near as possible to the ACS 600 intermediate circuit terminals (UDC+ and UDC–). Unprotected cable length must not exceed 0.5 metres.
