text: <s>[INST] Motion Control On Standard toshiba AC drives Summary: is it possible to control a standard ac drive using motion commandsMy goal is to use a compactlogix platform to create a master/slave setup using 2 toshiba G9 drives. Does anyone know if this is possible. i would like to use the motion instructions to control the drives speed outputs. i will be using a multi-turn absolute encoder on each motor the drives control. my thoughts are to use virtual axis in the program and map the output to the drives speed commands. [/INST] Compact Analog I/O is pretty slow, this would be my concern with trying to do this. All depends how tight you need the control to be. I've done things like this without using motion instructions, and it all comes down to how much precision you need and how much lag(and error) you can tolerate. What happens if they get out of sync? Is this a vertical application with brakes or horizontal? Or is it material handling? Really hard to give a general answer. \\n </s>
