Achieve significant speed difference and work into fast-forward

Mechanical power slide by the slide, slide and dual motor drive unit consists of three parts, the automatic working cycle slide by the mechanical transmission and electrical control is completed. In one cycle, to achieve the fast forward speed varies widely and work into, the ratio is usually up to 300:1. Fast forward, fast forward and rewind the motor to achieve,  power transformers  work into the motor to achieve. When the fast-forward into the motor while the motor and engineering work, the fast forward speed of the fast forward speed of the original plus a Work Speeds, rewind,  circuit breakers to the original speed minus a work into speed. Feed motor for the job, M2 is fast motion motor trip switch for the in situ conversion work for the end of the feed limit switch limit switch limit switch to limit protection.
