First of all, I know that my question is very specific for those who have hands on experience with the ASDA-A2 Servo Drive from Delta-Electronics. But I hope that someone will guide me through the solution of my problem.
I have a Delta ASDA-A2 Servo Drive and I want to send control commands from my PC through the COM port, so I have used a USB-RS485 converter from the same manufacturer of my drive which is called (Converter) IFD6500. The problem is when connecting the Servo Drive through the converter to the configuration software (ASDA-SOFT) I find that it's not working except under the 9600 baud-rate, and it gives me a lot of timeout failures and wrong communication messages. When changing the communication speed from the parameter P3-01 to any other higher baud-rate it gives me an error of device not found. I though that may be the problem is from the wiring of RS-485+ and RS-485- signal pins so I have replaced their position and I got a total communication failure. I want to solve this problem and get a successful communication with different baud-rates between my Servo Drive and PC Here are the pin-out diagrams of my devices:
