Unbalance Detection Routine

The unbalance detection routine occurs during the distribution ramp (while basket spin is accelerat- ing from 40 to 400 rpm). At 400 rpm the motor is decelerated and the rate of deceleration is moni- tored by the CCU. The motor is then ramped up to 400 rpm and shut off. The rate of deceleration is monitored again and compared to the first deceleration rate. Based on this comparison, the CCU can determine whether an unbalanced condition exists or not.

a.If the Motor Control Unit does not sense an unbalanced condition, the ramp will continue.

b.If the Motor Control Unit senses an unbalanced condition, the drive motor is stopped.
