EXTENDED REGISTER GROUPS<br />

Gear.CamInterp 22 0..2 RW<br />

0= Linear<br />

interpolate between two points as STD.<br />

1= Cubic<br />

trigonometric interpolation (4 points).<br />

The interpolator<br />

interpolates through each specified point.<br />

This may introduce<br />

undershoots, but by carefully selecting<br />

2= points a very nice smooth cam can be achived.<br />

Cubic BSpline interpolation (4 points).<br />

Does not interpolate through the control points, and does not<br />

undershoot.<br />

Normal PDATA lines are used as for the linear interpolation<br />

and it is possible to switch between the interpolation modes in<br />

real time, and also modify points in real time.<br />

i<br />

Gear.SlaveFixTm 23 0..2550<br />

Be aware that the motor will move to the new position<br />

with no speed limit! This is <strong>of</strong> the same nature as<br />

modifying the point we are currently interpolating.<br />

Fix time base for virtual master mode <strong>of</strong> gearbox<br />

Gear.PreCamLine 24 See Gear.Camline<br />

Preset value for Gear.Camline<br />

Gear.PreCamLen 25 See Gear.Camlen<br />

Preset value for Gear.Camlen<br />

Gear.PreCamscale 26 See Gear.CamScale<br />

Preset value for Gear.CamScale<br />

Gear.PreCamInc 27 See Gear.CamInc<br />

Gear.PreCamSet 28<br />

Preset value for Gear.CamInc<br />

Force setting <strong>of</strong> preset values by writing to Gear.PreCamSet<br />

when written the above Preset values are copied into the<br />

corresponding gearbox parameters. This allowing for dynamic<br />

switching <strong>of</strong> cam parameters<br />

Gear.CamPeriods 29 -2 31 ..2 31 -1 RW<br />

Number <strong>of</strong> periods <strong>of</strong> the cam. This value increments for each<br />

period <strong>of</strong> the cam, (signed).<br />

Gear.PosRef 30 -2 31 ..2 31 -1 R<br />

Actual reference out from the Gear/Cam function that are<br />

used by the regulator. Valid only if Pos Mod On has been<br />

activated. Shows Gear.Pos in the case <strong>of</strong> gearing and shows<br />

Gear.CamPos in the case <strong>of</strong> cam usage.<br />
