Ixx37 Motor xx PID Notch Filter Coefficient N2
Range:
-2.0 - 2.0
Units:

Usually, this parameter is set initially using the Tuning utility in the PMAC Executive Program. It may
be changed on the fly at any time to create types of adaptive control.

Ixx40 Motor xx Net Desired Position Filter Gain
Range:
0.0 – 0.999999
Units:
none
Default:
0.0
Ixx40 permits the introduction of a first-order low-pass filter on the net desired position for Motor xx.
This can be useful to smooth motion that comes from a “rough” source, such as master following from a
noisy sensor, or quantization error in very closely spaced programmed points that are commonly found in
lookahead applications.

If Ixx40 is set to its default value of 0.0, this filter function is disabled. If Ixx40 is set to any value greater
than 0.0, the filter is enabled.
than 0.0, the filter is enabled.
Ixx40 can be expressed in terms of the filter time constant by the following equation:
