To ensure the smoothness of the winding process, whether PFSA 140 is large or small, acceleration, deceleration, activation, or parking, constant tension can be ensured. Torque compensation is required. To activate the entire system, the first step is to overcome the torque generated by static friction, abbreviated as static friction torque. Static friction torque only works at the moment of activation; During normal operation, it is necessary to overcome the sliding friction torque generated by sliding friction. Sliding friction torque always exists during operation and its magnitude varies at low and high speeds. Compensation of different sizes is required. To overcome the inertia of the system during acceleration, deceleration, and parking, corresponding torque compensation must also be carried out. The amount of compensation is proportional to the operating speed. The compensation coefficient varies at different speeds.

PFSA 140 acceleration torque, deceleration torque, parking torque, and activation torque; To overcome these factors, it is also necessary to overcome the load torque. By dividing the calculated real-time coil diameter by 2 and multiplying it by the set tension size, and converting it to the motor shaft through the reduction ratio, the torque compensation process of the entire winding process is analyzed. Summary: The output torque of the motor=static friction torque (at the moment of activation)+sliding friction torque+load torque. Acceleration torque should also be added during acceleration; When PFSA 140 , the deceleration torque should be subtracted. When stopping, because the deceleration is achieved through programmed deceleration to the set minimum speed, the compensation of the stopping torque is the same as the processing of the deceleration torque
