<p>The circuit is applicable to drives starting from rest in a work cycle, for example a wire drawing machine. The output to the speed controller is the acceleration signal (UH) and a supplementary signal (US) to overcome stickion effects, combine to give a reference (URZ). The proposed circuit adds the auxiliary signal to the integrator (1) as well as the output amplifier (2) thus, with the feedback loop (UC+US), making the effective acceleration signal dependent upon the difference between the maximum reference (URZ) and the auxiliary signal (US).</p> |
