丹佛斯FC51变频器设置指南
丹佛斯FC51变频器设置指南丹佛斯 FC51 变频器，在工业控制领域那可是个相当重要的角色。
对于不少搞电气控制的朋友来说，把它设置明白可不是一件简单的事儿。
今天，我就来给您详细唠唠这丹佛斯 FC51 变频器的设置指南。
先来说说我自己的一次经历吧。
有一回，我接到一个紧急任务，一家工厂的生产线突然停摆了，原因就是这丹佛斯 FC51 变频器出了问题。
我赶到现场一看，那叫一个乱啊！工人们都着急得不行，老板在旁边也是一脸的焦虑。
我赶紧静下心来，开始检查变频器的设置。
这丹佛斯FC51 变频器的设置，第一步就是要搞清楚您的具体需求。
比如说，您是要控制电机的转速呢，还是要实现精确的扭矩控制？不同的需求，设置的参数可大不一样。
接下来，就是连接硬件啦。
把电源线、控制线啥的都接好，可别接错喽，不然它可不听您使唤。
我记得有一次，一个新手把电源线和控制线弄混了，结果一通电，好家伙，直接冒了一股烟，把大家都吓了一跳。
设置参数的时候，那可得小心谨慎。
比如说，基本频率、最高频率、加速时间、减速时间等等，这些都得根据实际情况来调整。
就像有一次，我给一个风机调速，本来想着加速时间短一点能提高效率，结果设得太短了，风机启动的时候猛地一震，差点把旁边的零件都震掉了。
还有啊，丹佛斯 FC51 变频器有很多保护功能的设置也不能马虎。
过流保护、过载保护、过热保护等等，这些就像是给变频器穿上了一层防护服，能让它在恶劣的工作环境下也能稳稳当当的工作。
在设置过程中，您还得注意一些小细节。
比如说，参数的单位要搞清楚，有的是赫兹，有的是百分比，弄错了可就麻烦啦。
另外，设置完成后，一定要进行测试。
先空载运行一下，看看各项参数是不是正常，电机转得顺不顺。
有一回，我设置完没测试就直接上了生产线，结果运行起来电机抖动得厉害，又得重新返工，浪费了不少时间。
总之，丹佛斯FC51 变频器的设置需要您细心、耐心，按照步骤来，多注意细节，这样才能让它乖乖地为您工作。
希望我的这些经验能对您有所帮助，让您在设置变频器的时候少走弯路，顺顺利利的！。

Mechanical InstallationVLT ® Micro Drive FC 51 Operating Instruc-tions23.3.1.How to Connect3.1.1.Electrical Installation in GeneralNB!All cabling must comply with national and local regulations on cable cross-sections and ambient temperature. Copper conductors required, (60-75° C) recommended.Table 3.1: Tightening of terminals.3.1.2.FusesBranch circuit protection:In order to protect the installation against electrical and fire hazard, all branch circuits in an installation, switch gear, machines etc., must be short-circuited and overcurrent protected according to national/international regulations.Short circuit protection:Danfoss recommends using the fuses mentioned in the following tables to protect service personnel or other equipment in case of an internal failure in the unit or short-circuit on DC-link. The frequency converter provides full short circuit protection in case of a short-circuit on the motor or brake output.Overcurrent protection:Provide overload protection to avoid overheating of the cables in the installation. Overcurrent protection must always be carried out according to national regulations. Fuses must be designed for protection in a circuit capable of supplying a maximum of 100,000 A rms (symmetrical), 480 V maximum.NonUL compliance:If UL/cUL is not to be complied with, Danfoss recommends using the fuses mentioned in table 1.3, which will ensure compliance with EN50178:In case of malfunction, not following the fuse recommendation may result in damage to the frequency converter.VLT ® Micro Drive FC 51 Operating Instruc-tions3. Electrical Installation3Table 3.2: Fuses3.1.3.EMC-Correct InstallationFollowing these guidelines is advised, where compliance with EN 61000-6-3/4, EN 55011 or EN 61800-3 First environment is required. If the installation is in EN 61800-3 Second environment , then it is acceptable to deviate from these guidelines. It is however not recommended.Good engineering practice to ensure EMC-correct electrical installation:•Use only braided screened/armoured motor cables and control cables.The screen should provide a minimum coverage of 80%.The screen material must be metal, not limited to but typically copper, aluminium, steel or lead. There are no special requirements for the mains cable.•Installations using rigid metal conduits are not required to use screened cable, but the motor cable must be installed in conduit separate from the control and mains cables. Full connection of the conduit from the drive to the motor is required. The EMC performance of flexible conduits varies a lot and information from the manufacturer must be obtained.•Connect the screen/armour/conduit to earth at both ends for motor cables and control cables.•Avoid terminating the screen/armour with twisted ends (pigtails). Such a termination increases the high frequency impedance of the screen,which reduces its effectiveness at high frequencies. Use low impedance cable clamps or glands instead.•Ensure good electrical contact between the de-coupling plate and the metal chassis of the frequency converter, see Instruction MI.02.BX.YY •Avoid using unscreened/unarmoured motor or control cables inside cabinets housing the drive(s), where possible.3.

Normally, small motors are star-connec-ted (230/400 V, Δ/Y). Large motors are delta-connected (400/690 V, Δ/Y). Refer to motor nameplate for correct connection and voltage.Illustration 3.3: Star and delta connections.VLT ® Micro Drive FC 51 Operating Instruc-tions3.

It is assumed that the user has full knowledge of the capabilities and limitations of the controller.5.1.3.Modbus RTU OverviewRegardless of the type of physical communication networks, the Modbus RTU Overview describes the process a controller uses to request access to another device. This includes i.a. how it will respond to requests from another device, and how errors will be detected and reported. It also establishes a common format for the layout and contents of message fields.During communications over a Modbus RTU network, the protocol determines how each controller will learn its device address, recognise a message addressed to it, determine the kind of action to be taken, and extract any data or other information contained in the message. If a reply is required, the controller will construct the reply message and send it.Controllers communicate using a master-slave technique in which only one device (the master) can initiate transactions (called queries). The other devices (slaves) respond by supplying the requested data to the master, or by taking the action requested in the query.The master can address individual slaves, or can initiate a broadcast message to all slaves. Slaves return a message (called a response) to queries that are addressed to them individually. No responses are returned to broadcast queries from the master. The Modbus RTU protocol establishes the format for the master’s query by placing into it the device (or broadcast) address, a function code defining the requested action, any data to be sent, and an error-checking field. The slave’s response message is also constructed using Modbus protocol. It contains fields confirming the action taken, any data to be returned, and an error-checking field. If an error occurs in receipt of the message, or if the slave is unable to perform the requested action, the slave will construct an error message and send it in response, or a time-out will occur.5.1.4.Frequency Converter with Modbus RTUThe frequency converter communicates in Modbus RTU format over the built-in RS-485 interface. Modbus RTU provides access to the Control Word and Bus Reference of the frequency converter.The Control Word allows the Modbus master to control several important functions of the frequency converter:•Start•Stop of the frequency converter in various ways:Coast stop Quick stop DC Brake stop Normal (ramp) stop •Reset after a fault trip•Run at a variety of preset speeds •Run in reverse•Change the active set-up•Control the frequency converter’s two built-in relaysThe Bus Reference is commonly used for speed control. It is also possible to access the parameters, read their values, and where possible, write values to them. This permits a range of control options, including controlling the setpoint of the frequency converter when its internal PID controller is used.55.2.Modbus RTU Message Framing Structure5.2.1.Remote Terminal UnitThe controllers are set up to communicate on the Modbus network using RTU (Remote Terminal Unit) mode, with each 8-bit byte in a message containing two 4-bit hexadecimal characters.The format for each byte is shown below.Start bit Data bit Stop/pari-ty Stop5.2.2.Modbus RTU Message StructureThe transmitting device places a Modbus RTU message into a frame with a known beginning and ending point. This allows receiving devices to begin at the start of the message, read the address portion, determine which device is addressed (or all devices, if the message is broadcast), and to recognise when the message is completed. Partial messages are detected and errors set as a result - or timeouts occur. Characters for transmission must be in hexadecimal 00 to FF format in each field.The frequency converter continuously monitors the network bus, also during “silent” intervals. When the first field (the address field) is received, each frequency converter or device decodes it to determine which device is being addressed. Modbus RTU messages addressed to zero are broadcast messages.No response is permitted for boradcast messages. A typical message frame is shown below.StartAddress Function Data CRC check End T1-T2-T3-T41 byte1 byteN x 1 byte2 bytesT1-T2-T3-T4Table 5.1: Typical Modbus RTU Message Structure5.2.3.Start/Stop FieldMessages start with a silent period of at least 3.5 character intervals. This is implemented as a multiple of character intervals at the selected network baud rate (shown as Start T1-T2-T3-T4). The first field to be transmitted is the device address. Following the last transmitted character, a similar period of at least 3.5 character intervals marks the end of the message. A new message can begin after this period.The entire message frame must be transmitted as a continuous stream. If a silent period of more than 1.5 character intervals occurs before completion of the frame, the receiving device flushes the incomplete message and assumes that the next byte will be the address field of a new message. Similarly,if a new message begins prior to 3.5 character intervals after a previous message, the receiving device will ignore both messages. This will cause a time-out (no response from the slave).5.2.4.Address FieldThe address field of a message frame contains 1 byte. Valid slave device addresses are in the range of 0 - 247 decimal. The individual slave devices are assigned addresses in the range of 1 - 247 (0 is reserved for broadcast mode, which all slaves recognise). A master addresses a slave by placing the slave address in the address field of the message.5。
