Features 8-17
_Q32%.20 Selects S-ramps for the speed reference offset, _Q27%. The S-ramp
will take the same amount of time for as the linear ramp, but results in
a higher peak acceleration rate. (See
_Q13%). _Q12% is not used
when S-ramps are selected.
0 linear ramps.
1S-ramps.
_Q32%.27 Selects between rigid and non-rigid digital lock modes. In rigid lock
mode, position lost during acceleration is recovered by running at a
higher speed (
_Q15%) than the reference. Once position is
recovered, the axis will maintain position and speed lock. In non-rigid
lock, the position lost during acceleration will not be recovered, and
the slave will run with speed lock only.
0 rigid digital lock.
1 non-rigid digital lock.
_Q32%.28 Ramps can be applied to the slave reference to prevent excessive
rates of acceleration and deceleration, particularly when digital lock is
enabled. If ramps are not selected, the auxiliary encoder reference is
simply multiplied by the ratio (
_Q11%).
0 enable ramps.
1 disable ramps.
_Q32%.29 Disables the automatic writing of the return position (_ Q40%) to
_Q2% when switching out of digital lock control to position control
(
_Q32%.2 from 1 to 0). When disabled, _Q2% is updated once when
digital lock is deselected, allowing a smooth stop with no overshoot.
0 enable automatic home position.
1 disable automatic home position.
_Q32%.30 Provides a limit switch function to prevent the axis travelling beyond
a certain point when using the position reference
_Q2%. When
_Q32%.30 is set, and the speed is positive (direction is forwards),
_Q2%, _Q4% and _Q9% are forced to the current feedback position
(
_Q8%), causing an instantaneous stop with no ramps.
NOTE: This function will only work when running
0 no action.
1 limit switch active.
_Q32%.31 Provides a limit switch function to prevent the axis travelling beyond
a certain point when using the position reference
_Q2%. When
_Q32%.31 is set, and the speed is negative (Direction is backwards),
_Q2%, _Q4% and _Q9% are forced to the current feedback position
(
_Q8%), causing an instantaneous stop with no ramps.
NOTE: This function will only work when running in position
control, and the feedback source is
_Q8%.
0 no action.
1 limit switch active.
