Subject: | Proper initialisation of Motor Record .RMP value |

We're pretty new at controlling motors using EPICS and we've run into a few small issues. After a crate reboot, some of a bank of 28 motors end up with a motor.RMP value that is quite close to the signed 32-bit integer limit (both at max and min ends). If we then try move the motor more than the difference, the motor just stops. We're not running a complicated setup, we just home the motors using limit switches. We do not use encoders at this time. My question is, how do we properly initialise the .RMP value to some known value, probably zero? At this stage of the game, we're not looking to use an autosave module or similar.
