_
Q32%.8 Selects S-ramps for the position reference profile. The acceleration
profile will be sinusoidal. When S-ramps are selected, the
acceleration and deceleration rates are defined by
_
Q13%. If the
digital lock or cam table references are selected,
_
Q32%.8 will be
reset to disable the S-ramps.
NOTE: the position offset reference (
_
Q26%) cannot be used when
running in position control with S-ramps selected.
0 linear ramps.
1 S-ramps.
_
Q32%.12 Selects the cam table position reference when the auxiliary marker
pulse is seen by setting
_
Q32%.4 to 1.
_
Q32%.12 is reset after
_
Q32%.4 has been set. The cam table can only be used if the CAM
function has been correctly initialised.
0 no action.
1 enable cam table with auxiliary marker pulse.
_
Q32%.14 Selects the digital lock output position reference when the auxiliary
marker pulse is seen by setting
_
Q32%.2 to 1.
_
Q32%.14 is reset
after
_
Q32%.2 has been set. The auxiliary encoder input is also
latched so that rigid lock can be achieved (see
_
Q32%.27).
0 no action.
1 enable digital lock with the auxiliary marker pulse.
_
Q32%.17 Provides a quick and easy method to reset all read-only position
parameters. This does not affect configuration parameters, or the
latched encoder position values. When all values have been reset,
_
Q32%.17 is reset. This parameter should not be set when the Drive
is running, as it will cause a hard stop without ramps, and all position
information will be lost.
0 no action
1 reset all position parameters.
_
Q32%.19 Selects S-ramps for the speed reference
_
Q3%. 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.
NOTE: S-ramps are not available when accelerating up to line speed
under digital lock control.
0 linear ramps.
1 S-ramps.
