It...
The profibus dp accessory of the cfw500 frequency inverter provides an rs485 interface for network connection. 1.5 application profile – profidrive complementary to the profibus protocol specification, the profidrive specification, elaborated and kept by the profibus international, basically describ...
2 profibus dp communication accessory the following profibus dp accessory is needed in order to enable the device communication in a profibus dp network. Information about the installation of this module can be found in the guide that came with the accessory. 2.1 plug-in module cfw500-cpro weg part ...
3 installation in the profibus dp network the profibus dp network, such as several industrial communication networks, for being many times applied in aggressive environments with high exposure to electromagnetic interference, requires that certain precautions be taken in order to guarantee a low com...
Connected to the network. Each repeater must also be included as a device connected to the segment, even not occupying a network address. It is recommended that the connection of all the devices present in the profibus dp network be made coming from the main bus. Generally, the profibus network conn...

In order that the reference written in this parameter be used, it is necessary that the drive be programmed to use the speed reference via canopen/devicenet/profibus dp. This programming is achieved by means of parameters p0221 and p0222. This word uses a 13-bit resolution with signal to represent t...

5 profibus dp network operation the cfw500 frequency inverter with profibus dp communication accessory operates as a slave in the network and supports the network services of dp-v0 and dp-v1 communication protocols. Information about the inverter operation using the services specified on these versi...
Communication between class 2 master and slave (ms2): initiates the connection (initiate) data acyclic reading (ds_read) data acyclic writing (ds_write) aborts the connection (abort) dp-v1 requests use an sd2 type profibus dp telegram – with variable data length.

2. When receiving the telegram, the cfw500 will test the data consistency in order to know if the request is valid. If errors in the request format are not found, it will respond positively to the request telegram and initiate the data treatment. 3. After receiving writing telegram positive response...

6 faults and alarms related to the profibus dp communication a138/f238 – profibus dp interface in clear mode description: it indicates that the slave has received from the network master the command to enter the clear mode. Actuation: the indication occurs if, during the cyclic communication, the pr...
The message of alarm a140 or fault f240 will in this case be signalized through the hmi, depending on the p0313 programming. It is necessary to cycle the power of the drive so that a new attempt to access the profibus dp module is done. Possible causes/correction: verify whether the profibus dp modu...
