Acceleration Enable
When this check box is selected it allows a gear to run a specified accel ramp after the gearing command is turned On.
Acceleration
This parameter sets the acceleration of the realtime gearing ramp. Gear.Accel units are in Follower Units/Velocity Time Base/
Acceleration Time Base. The Gear.Accel functions only when the follower is ramping its speed up to meet the Masters at the
specified Gear.Ratio.
Deceleration Enable
When this check box is selected it allows a gear to run a specified decel ramp after the gearing command is turned Off.
Deceleration
This parameter sets the deceleration of the realtime gearing ramp. Gear.Decel units are Follower Units/Velocity Time Base/
Acceleration Time Vase. The Gear.Decel functions only when the follower is ramping its speed down meet the Masters at the
specified Gear.Ratio.
8.7.5 Camming View
Electronic cams provide a non-linear motion function for a single axis. The basic motion can best be illustrated in Figure 111 of
a mechanical cam and cam follower (or slave).
Figure 144: Mechanical Master and Slave Follower
As the master axis (the cam lobe) rotates, the follower axis produces a non-linear motion profile. This same profile can then be
produced with a single motor driving a linear axis programmed with an electronic cam.
The cam motion object uses a master/follower principal in a synchronized mode and also has a follower with Realtime mode
that allows the follower to travel through its cam table without a physical master axis moving.
Control Techniques provides a Cam as a collection of cam table(s) that can be used individually of chained together to form a
full sequence of motion. Each cam table is a user specific sequence of movements whereby the user can specify the master
and follower movement along with the interpolation type. Coupled with a user program to monitor the flow, the motion can
dynamically be altered by changing the cam table chains selecting a different sequence of tables. You can further adjust the
flow by dynamically changing the cam tables themselves or using a cam table time base index to adjust time or distance.
As an alternative, the cam is initiated in the same manor as jogs, home and indexes.
