If you mean to control the position of a machine as a closed-loop servo system, using the RS232 output, the answer is no. EMC by default reads encoder position 1000 times a second. It is highly unlikely the RS232 output of your DRO updates more than a couple times a second. Depending on the type of signals coming from the scales directly, they may be usable. The position resolution os fairly low, however. I assume 1/5thou means ~.0002", which is actually 0.005mm Servo control works a lot better with a higher resolution.
