Roboform 55 rapid travel speed

We have a Roboform 55 that when installed the service man increased the rapid travel speed of the machine 20 years ago. The last time I reloaded the software the travel speed has decreased to a slow crawl. It takes me longer to touch off my electrodes now that it does to do the actual EDM work. Does anyone know were the parameter is to increase the travel speed of the machine?
