Not able to establish communication with yaskawa sgda-08as (serpack not found)

Hi Group,


I have a Yaskawa SGDA-08AS Servopack that I am trying to use to control a Yaskawa SGM-08A314SP servo motor. I am trying to establish communication between my PC and the Servopack using the Sigmawin+ 5.75 software. I am using a USB to RS-422 communication cable between the PC and the Servopack. It seems that no matter what I do I get the "servopack not found" message. I have double checked my port settings (baud: 9600, data: 7 bit, parity: even, stop: 1 bit, XON/XOFF: none) and currently do not have the CN1, CN2, or motor cables hooked up. I just 110VAC power to the drive and the operator communication cable. 1 thing I have noted is the alarm led comes on along with power led, I do not know if this is normal or not. Is there something obvious that I am missing or a little known setting I cannot find? Any insight into this issue is sincerely appreciated and if there is any other info that is needed please let me know. Thank you all in advance for your time.
