Vertical Drive adjustment (for adjustable drive only)
The aim of the adjustment is to minimize the oscillation of the drive system. Therefore, one has to
adjust an optimized axle distance between the pinion and the Tension gear. First, to determine the
reference position the excentricity of the Tension gear must be measured. From this position the
pinion is moved stepwise. The corresponding angles are measured and the step angle errors are
recognized and later minimized.
