Ax5000 – internal filters

When working with the described filters there is always a danger of the motor performing uncontrolled movements due to impermissible parameterisation. High pass op amp filter Make sure that your application allows these movements and secure the entire danger zone against inadvertent entry; ensure that no persons are in the danger zone.

The control quality describes the capacity of the drive system to follow the setpoint values highly dynamically, with low losses and fail-safe. What is high pass filter car audio The control quality depends on many factors.


High pass filter rl circuit On the mechanical side these could be soft drive trains with belt drive, or resonance points caused by the natural ageing of components or special features of the mechanical structure. Rc filter calculator high pass Without the use of filters the only possibility is to reduce the loop gain and to adapt it to the worst condition. High pass filter gain formula However, this adaptation affects the total application and lowers the dynamics of the drive system. High pass filter fourier transform The application and the parameterisation of the internal speed and current filters act, for example, specifically on a resonant frequency, hence allowing a high loop gain and thus a highly dynamic drive system. High pass filter design calculator The filters described here serve to eliminate or attenuate unwanted noise or resonant frequencies.

The drive system receives the input parameter “Speed n = 40 rpm” from the PLC. High pass or low pass filter If the drive system is operating under optimum conditions, the motor achieves this speed with very good control quality. Rc high pass filter pdf The different characteristics of the drive system also cause sources of resonance among other things, which are always disturbing. High pass filter definition They often manifest themselves in oscillating shafts or hum frequencies. High pass filter circuit Overlaid signal oscillations of the encoder systems can similarly create high frequency noise, thus reducing the control quality.
