Photoelectric sensor behind guiding roller
Type of compensating for the breadth.
¡ñ introduction of system
The system with the time lagging compensating amplifier which the guiding signals from controller is the enhanced signal related to the system’s running so as to speed up transverse moving must be selected for decreasing the effection of time lagging When the photoelectronic sensor can not be installed close to the uncoiler caused by the constructure and resulting in unsatisfied affect of delaying reaction.
The signal of uncoiler’s position will be return from displacement sensor to controller and form a close loop.
