That is, the host controller calculates a speed reduction  N occurring when the moment of inertia of a motor 20 and load is accelerated or decelerated at a certain acceleration or deceleration rate. The compensation quantity  Nref for speed reduction is obtained when the calculated speed reduction  N is applied to the time-lag of first order having the response time of an automatic speed regulator 10 as a time constant. Then, the compensation quantity  Nref is added to a speed command value Nref via addition point 33. Thus, the speed reduction due to drooping can be compensated according to the characteristics of the motor 20, load and automatic speed regulator 10.

However, among those ribs of the parallelogram the rib 10 of a slant-wise direction prevent a band C from cracking longitudinally and the rib 9 of a longitudinal direction gives stiffness of a longitudinal direction and softness of a widthwise direction to the band.
