Abstract
A system that limits the torque of motors and discontinues motion control activity of system components in order to protect electrical and mechanical system hardware. Mechanical stresses are controlled by a microprocessor in a manner that they will not exceed predefined limits so that mechanical components will not be destroyed. Thus, replacement of major system components such as drive electronics and fuses may be avoided. Hence, there will be a reduction in service calls to repair the motors and system components.
