If the dyno has timed out or just keeps running at the move to speed the data system was not able to find a displacement channel reading. The most common problem is the electronics board power cord not plugged in or the motor properties are set incorrectly.

As simple as it may sound many dyno problems are the machine not plugged in. There are TWO  power cables to all REI dynos. The high voltage cable is the large gray cable that powers the inverter and motor this will be 220-480 volt. Make sure this cable is connected and the power is on. The second cable powers the data electronics, this will have a standard household plug. Make sure this is plugged into a know good power source. Many problems are traced back to a faulty power strip.

The dyno might time out if it can't find a point such as gas test or BDC. Go to HARDWARE/MOTOR click through the warning in the next window. This should bring you to the Roehrig Hardware window. select the CONFIGURE button. The next window is the motor properties window. In this window make sure the MOVE CONTROL tolerance is set at 6% and the Frequency is .11 Hz.
