Velocity Test
1. Disable the drive.
2. Select Velocity Analog mode and set "Full Scale Velocity" parameter to 12 RPM.
3. Use the simulator to adjust the analog command voltage to 5 volts.
4. Enable the drive. Find the "Velocity Command Analog" parameter on the Status tab.
Adjust the analog command until this parameter reads exactly 6 RPM. The motor should
be moving at 6 RPM. If the system got through the Torque test, the motor should not run-
away at this point. If it does, go back and repeat the Torque test.
5. Confirm that the motor velocity is really 6 RPM by confirming that it takes 10 seconds
to make one revolution. If this is not the case, the problem may be that both the motor
poles and the encoder line density are off by the same factor.
6. Reduce the analog command voltage to zero volts and disable the drive.
