ST500 | Skip frequency – skip a critical frequency what is to be parameterised here?
There are many applications in which certain operating frequencies lead to resonant vibrations of the motor. In order to pass through these frequency ranges quickly, it is possible to set up blocking ranges in the frequency inverter. It is possible to specify two ranges. Their centre frequencies are set with parameters F7.04 and F7.05, and with F7.06 the range before and after the frequency to be passed is specified.
F7.04 = 44 (the frequency to be passed over) e.g. 44Hz
F7.06 = 3 (the frequency range before and after the frequency) e.g. ±3Hz gives a jump from 41 to 47Hz
F7.07 = 1 (skip the frequency ranges also during starting and braking, if needed)
