04/07 AWB8230-1541GB Reference and control signalinputsMinimum and maximum operating frequencyWith PNU A061 and A062 you can limit the frequency rangedefined with PNU b082 (starting frequency) and PNU A004 (endfrequency) (a fig. 94). As soon as the frequency inverter receivesa start signal, it outputs the frequency set with PNU A062; atmaximum reference frequency, the frequency set with PNU A061.f[Hz]A004A061A0620 tb082Figure 94:Upper frequency limit (PNU A61) and lower frequencylimit (PNU A062)PNU Designation RUN b031= 10Value Function DSA004A204A061A062A262b082End frequency(fmax)MaximumoperatingfrequencyMinimumoperatingfrequencyIncreasedstartingfrequency (e.g.at high staticfriction)– – 30…400 Hz Maximum output frequency 50{60}– j 0…400 Hz This function can be deactivated by entering 0.0. 0.00…400 Hz 0.0– j 0.5…9.9 Hz A higher starting frequency results in shorter acceleration anddeceleration times (for example to over<strong>com</strong>e high frictional resistance).If the frequencies are too high, fault message E002 may be issued. Upto the set starting frequency, the motor accelerates without a rampfunction.0.5For further information, see section “Limit and target values”,page 68.91
