NOTE: In some cases the power stack rating may determine what motor overload settings are available. Each power stack is

designed to support specific motor overload classes. The RBX power stack is designed for class 10 duty without derating. Refer to

the RBX Hardware Manual for the specifics of the RBX overload capabilities. Also, in certain heavy duty DC braking applications,

the overload settings may be limited to protect the motor from potential damage during braking.
