20 %, for 8- and 10-pole motors at approx. 15 % and higher pole motors at approx. 5 %. For the control of motors made by other manufacturers (not Ziehl-Abegg), the control characteristics and the maximum current for electronic regulation of the voltage should be enquired from the manufacturer. -
Page 10: Motor Noise
Dcontrol Operating instructions Date 0730 5.4 Motor noise Motor noise can occur when fans are controlled using electronic voltage controllers (Phase cutting = series “P...”). Such noise can be system-dependently perceived as a disturbance. This noise is relatively low for fast-running fans where the noise from the air is high. -
