If the output scale is in volts ( which is pncconfs default), note that you
can calculate an approximate FF1 value if you know the joint velocity at 10V:
FF1 = 10/Vel@10V
And alternate way to do this is to scale the analog output so a command of
full scale speed results in a 10V output, then FF1 = 1.0
For example, if a joint speed is 200 mm/s at 10V, setting the output scale
to 200 means that FF1 would be 1.0.
If you change the output scale you also need to set the min and max limits
to match
