I am actually using a STEPPER and a DC at the same time. Thus sometimes my POST refer to a STEPPER and sometimes a DC. I need the STEPPER to move up/down at a constant rate all the time. However for the DC I need to set the speed at a constant. However When I start the EXPERIMENT the voltage on the DC is the same but RPM of the DC will change due to OTHER factors. I need to increase or decrease the voltage supplied to the DC to keep the RPM constant. A friend has made a labview program in labview 6.0. I have attached it to this message.
