Hello rameshreee;
I really must insist that you take some time and study the manual I proposed earlier. Most of the questions you are asking find their answers in that document.
For example, look at the attachment I have taken from that manual.
You will see that there are 3 possibilities of controlling this drive, through digital inputs, analog inputs and USS protocol. No pulse input (for PWM).
If you choose to use digital inputs (parameter P006 to 000), you will have to connect a 24 V DC digital output from the PLC between pins 5 and 9 to control Digital Input 1 (selected by P007 set to 1), as described in the extract in my previous post. Connecting between 6 and 9 gives you control of DIN 2....
What speed command will be sent to the motor will depend on the parameters that you have selected for the drive (in P005, in Hz).
Analog outputs from your PLC can be programmed to operate the drive too. Look at the information on analog control in the manual.
Do you understand now the relationship between physical commands and parameters? For exampleYou need to enable DIN 1 (P007) for the digital command (pins 5 and 9) to operate correctly. The set speed selected for DIN 1 will be selected by you in parameter P005.
Your question on the connection of the internal RS-485 is found on this page also: if you decide to use USS protocol then you are limited in the selection of other elements using the external port, such as a OPM2 operator panel.
USS is a control protocol you can use from a S7-200 CPU (there is an add-on library for it) that will allow you to send control and speed command in real-time to this drive, serially (no Profibis-module required on the drive or on the PC)without having to control though digital or analog inputs.
Again, look at the manual, and try to understand it properly, it is the best advice I can give you.
Hope this helps,
Daniel Chartier
