Epsilon EP-B Base Drive Reference Manual
Feedforwards can be enabled in any operating mode, however, in certain modes they do not function. These modes are
described in table below.
Low Pass Filter Group
The Low Pass Filter will reduce machine resonance due to mechanical coupling and other flexible drive/load
components by filtering the command generated by the velocity loop. A check box on the Tuning view enables a low
pass filter applied to the output of the velocity command before the torque compensator. The low pass filter frequency
parameter defines the low pass filter cut-off frequency. Signals exceeding this frequency will be filtered at a rate of 40
dB per decade. The default value is 600Hz.
