Motion Smoothing: To eliminate the
jerk of mechanical systems, the
DMC-1000 provides profile smooth-
ing. The acceleration profile is fil-
tered with the IT command for inde-
pendent moves and the VT com-
mand for coordinated moves.
Contouring: The contouring mode
allows the user to bypass the DMC-
1000 motion profiler and prescribe any
arbitrary position trajectory. Position
increments (CD) over a time interval
(DT) are specified for each axis. The
contouring mode is useful when com-
plex and computer-generated trajecto-
ries must be followed. An automatic
data recording feature allows the
DMC-1000 to "learn" a path and then
follow it in the contour mode.
Electronic Gearing: This mode
allows up to eight axes to be elec-
tronically geared to one master axis
which may or may not be a motor
controlled by the DMC-1000. The
master axis (GA) may rotate in both
directions and the geared axes will
follow at the specified ratios (GR).
The gear ratio can be changed during
motion. An axis can be geared and
do an independent or vector move
simultaneously which is useful for
the precise synchronization required
in flying-shear applications. The elec-
tronic gearing mode eliminates
mechanical gears and is also useful
for gantry applications.
Electronic gearing. Example:
GAY
Y is master
GR 5,,-2.5 X ratio=5, Z ratio=-2.5
PR,10000 Specify Y distance
SP,10000 Specify Y speed
AC,25000 Specify Y acceleration
DC,25000 Specify Y deceleration
BG Y
Begin motion
Electronic Cam: This mode allows
synchronizing up to seven axes with
a master axis according to any func-
tion. The cam functions, which are
specified by a table, define the
required position of the followers
point by point along the motion
cycle. The master axis may be a dri-
ven axis or just a master encoder. It
may rotate in either direction.
The position of the master axis
and the follower axes may be
expressed in modulo form, limiting
the value to one cycle. This simpli-
fies the description of points and
events along the cycle.
Any follower axis may be
engaged or disengaged independent-
ly at specific points along a cycle.
This allows selecting the engagement
