MACHINE PARAMETERS
SOFT: V02.2X
Axis parameters
The best adjustment is achieved when minimizing the following error as much as possible but without
inverting the peaks. The peaks of the right graph are inverted. Bad adjustment.
FFGAIN (P25)
Indicates the % of velocity command due to the programmed feedrate. The rest will depend upon
the following error. Both the proportional and derivative gains will be applied onto this following error.
The feed-forward gain improves the position loop minimizing the following error, but it should only
be used when working with acceleration/deceleration.
The graph on the left shows the system response without DERGAIN (10 m per
square) and the one on the right with DERGAIN (1 m per square).
Possible values
Between 0 and 100.99 (numbers with two decimals).
Default value: 0 (feed-forward gain not applied)
