Servo position/stress detection control system

A servo stress detection control system comprising:

• a servomotor having a rotation force output unit having a spindle;
• a servo driver having
• a control unit being electrically connected to the servomotor, selectively driving or stopping the servomotor and converting a torque value of the servomotor to a force value;
• and
• a register being electrically connected to the control unit and storing the force value;
• and
• a controller having
• an operating unit having a calculating program, being electrically connected to the register, accessing the force value stored in the register and converting the force value to a load stress value with the calculating program.

A servo position/stress detection control system comprising:

• a servomotor having
• a rotation force output unit having a spindle;
• and
• an encoder being connected to the spindle of the rotation force output unit;
• a servo driver having
• a control unit being electrically connected to the servomotor, selectively driving or stopping the servomotor and converting torque value of the servomotor to a force value;
• an absolute angle reading unit being mounted aside the encoder and reading an absolute angle value in response to rotation of the spindle;
• and
• a register being electrically connected to the control unit and the absolute angle reading unit and storing the absolute angle value and the force value;
• and
• a controller having
• an operating unit having a calculating program, being electrically connected to the register, accessing the absolute angle value and the force value stored in the register, converting the absolute angle value to a linear displacement with the calculating program, converting the force value to a load stress value with the calculating program, establishing a load line in response to different force values of the servomotor 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.
