ABSTRACT:
A servo position/stress detection control system has a servomotor, a servo driver and a controller. The servo driver has a control unit, an absolute angle reading unit and a register. The control unit selectively drives or stops the servomotor and converts torque value of the servomotor to a force value. The absolute angle reading unit reads an absolute angle value of rotation in response to a spindle of the servomotor. The controller respectively converts the absolute angle value and the force value to a linear displacement and a load stress value with a calculating program, establishes a load line in response to different force values and corresponding linear displacements wherein the load line provides corresponding correction basis for the servo driver to automatically detect height variances caused by reacting force and accordingly adjust working status of the servomotor.
