Final Adjustments Roughness and instability of motor operation are often the result of a loosely mounted
feedback device. Incorrect adjustment of the Level 1 DC Control, ARM PROP GAIN
parameter and/or the SPEED PROP GAIN can also cause speed instability and
oscillation of the car.
Note: It is desirable to have the ARM PROP GAIN as high as possible without
oscillation and the SPEED PROP GAIN as low as possible without rollback or
overshoot.
If adjustment of the SPEED PROP GAIN parameter does not help, check the feedback
device for lost motion. Any lost motion from either the coupling or the mount will affect the
motor’s operation.
