Note regarding Profibus FMS This manual does not deal with Profibus FMS, only with Profibus DP. However, in th
12、e event that the communication is to be built up through Profibus FMS, you should request the description MG.10.E3.yy ”Profibus Product Manual“ which also contains a description of the Profibus FMS func- tions of the Profibus option card.

13、demark3 I About this manual This manual is intended as both an instruction ma- nual and a reference guide. It only broaches the basics of the PROFIBUS DP protocol, and only when it is necessary to provide a sufficient under- standing of the PROFIDRIVE implementation of the PROFIBUS profile for varia
14、ble speed drives (version 2, PNO) and of the PROFIBUS option card for the series VLT 5000 by DANFOSS. In addition, the manual is intended to serve as a guidebook for the specification and optimization of the existing communication system. It is suggested that readers who are not completely familiar
15、with PROFIBUS DP or the profile for varia- ble speed drives review the relevant literature on these subjects. Even experienced PROFIBUS programmers should read the entire manual prior to programming, since every chapter of the manual contains important information. Chapter 2 deals with the quick sta
16、rt of the com- munication parameters for the DP communication. Chapter 3 contains details regarding the PROFIBUS option card and the establishment of the physical connection. Please refer to chapter 4 for information regarding the time behaviour. Chapter 5 presents an overview of the PPOs (infor- ma
17、tive data telegrams). The PCA interface as a parameter interface in the PPO is explained in chapter 6. Chapter 7 contains the description of the parame- ter and data structure. Chapter 8 contains a description of spontaneous messages. The response to the ”Sync” and ”Freeze” commands is explained in
18、chapter 9. The control word and status word as essential elements of the PPOs for the operational control, as well as the bus reference value are explained in chapter 11. Chapter 12 contains examples for the use of the PPOs. It is recommended that readers review the examples for a better understandi
19、ng of the PPOs. Comments regarding the GSD file can be found in chapter 13. Chapter 14 contains the VLT parameters specific to the Profibus. Warning and alarm messages and display readings specific to the Profibus are described in chap- ter 15. A parameter listing as an overview of all VLT 5000 para
20、meters can be found in chapter 16. In chapter 17 you will find the abbreviations used in this manual. The manual concludes with a short glossary and a detailed index for quick navigation. If you are interested in learning more about the PROFIBUS protocol in general, we recommend that you consult the
21、 relevant, very comprehensive literature for this purpose. I Assumptions The manual assumes that you are using a DANFOSS PROFIBUS option card with field bus, together with a DANFOSS VLT5000 series frequen- cy converter, that you are using a PLC or a PC with a serial interface as master which support
22、s all communication services for PROFIBUS, and that all requirements are met and all limitations are observed which arise from the PROFIBUS stan- dard, the PROFIBUS profile of variable speed dri- ves, and the company-specific implementation of PROFIDRIVE, or those of the VLT drives. I Background kno
23、wledge The DANFOSS PROFIBUS option card is designed for the communication with all masters that comply with the PROFIBUS standard. Thus, the assump- tion is made that you are familiar with the PC or PLC to be used as a master on your system. Any questions regarding the hardware or software of other
24、suppliers are beyond the scope of this ma- nual and outside the responsibility of DANFOSS. In the event of questions concerning the configura- tion of the master-to-master communication or the configuration with a slave not manufactured by DANFOSS, you should refer to the information in the respecti
25、ve manuals.

32、 gathered from the manual for the VLT 5000 series. The communication is established by setting the parameters indicated below. Details regarding the adjustment of the master are provided by the master manual and by those chapters in this manual that deal with the particu- lars of the VLT PROFIBUS in
33、terface. The required GSD file is available on the internet at http:/www.danfoss-sc.de. I I I I I Profibus DP Parameter 904 This selects the desired informative data telegram (PPO). Parameter 918 This sets the address of the VLT station one specific address per VLT. Parameter 801 This determines the
34、 transmission speed in bit/s. The standard setting is 1.5 MBaud. Parameter 502 = ”BUS“. As an alternative to the switching of terminal 27, the parameter 502 may be set to ”BUS“ in the factory setting before the motor can even be started. Please note the logic links of the parameters 502- 508 to the
35、clamping functions which are also active in the Profibus. (See operations manual for an explanation.) The VLT must be switched off/on once after the Profibus parameters have been set. Quick start When configuring the PPO types, a distinc- tion is made between module consistency and word consistency:
36、 Module consistency means that a specific portion of the PPO is defined as a connected module. The parameter interface (PCV, length of 8 bytes) of the PPO always has module consistency. Word consistency means that a specific portion of the PPO is divided into individual data sectors of word length (
37、16 bits). The process data of the PPO may have either module consistency or word consistency, as desired. Some PLCs, such as Siemens S7, require special functions to call modules that are longer than 4 bytes (in the case of Siemens: ”SFC”, see master manual). This means that the PCV interfaces of th
38、e PPOs can only be called through the SFC functions in the case of Siemens (S7).

40、teri- zation of variable speed drives. The PROFIBUS card behaves like a part of the VLT and enables access to all parameters that are important for the respective application. The variable speed drive always acts as slave and is capable of exchanging a multitude of commands and pieces of informa- ti
41、on together with the master. Control signals such as ”speed reference value”, ”start/stop” of the mo- tor, ”reversion” are transmitted by the master in the form of telegrams. The VLT confirms the receipt by transmitting status signals such as ”operation enabled”, ”reference value reached”, ”motor st
42、opped” etc. to the master. The drive can also report errors and transmit alarm and warning messages, e.g. ”VLT error” or ”excess current”. The PROFIBUS option card transmits signals in accordance with the PROFIBUS field bus standard, EN 50170, part 3. It can thus exchange data with all masters that
43、meet this standard; however, this does not mean that all services available in the PROFIBUS standard are supported. The PROFIBUS profile for variable speed drives (version 2, PNO) is a part of PROFIBUS which supports only those services that concern applications with speed control. PROFIDRIVE is an
44、implementation of the profile developed by DANFOSS and several other firms. Communications partner The variable speed drive always acts as slave in a control system and may thus exchange data with one or more masters, depending on the type of the application. The master may be a PLC or a PC with a P
45、ROFIBUS communications I Cable lengths and number of nodes The maximum cable length of a segment depends on the transmission speed. The total cable length includes stub lines, if applicable. A stub line is the connection from the main bus cable to each node if a ”T” connection exists instead of a di
46、rect con- nection of the main bus cable to the nodes; cf. the stub line length. The following table shows the maximum permitted cable lengths and the maxi- mum number of nodes or VLTs with 1, 2, 3 or 4 bus segments. Please note that a repeater switched between two segments represents a node in both
47、segments. The number of VLTs is based on a system with only one master. In the case of multiple masters, the num- ber of VLTs must be reduced accordingly. The total stub line length of a segment is limited as follows: Stub line length TransmissionMax. stub line length speedper segment m 9,6-93,75 kB
