The filename (up to 32 characters) describing the

cam motion.

Ultraware generates Cam files when you insert a

cam table under the “Cam” branch in the

workspace. The cam files generated by Ultraware

are always stored in the drives flash file system

under a directory named /Cam.dir. If a cam table

is created in Ultraware with the default name of

Table.cam, and loaded into drive memory, the File

Name will be “/Cam.dir/Table.cam”. User

programs may set the Camtable Filename

attribute to different paths.

64

Set

Cam Enable

Command

USINT

1

Causes the cam to begin generating an output

position. A cam table file must be loaded to

enable cam, or an “Invalid State” error occurs.

0 = No Action (default)

1 = Execute Command

65

Set

Cam Disable

Command

USINT

1

Causes the cam to stop generating output, but the

Cam Current Position output is held constant at

the current value.

0 = No Action (default)

1 = Execute Command

66

Get

Cam State

USINT

1

The current state of the cam:

0 = Disabled

1 = Enabled

67

Get

Cam Input

Position

DINT

4

cnts

The current master position value. This value will

roll over to zero as it passes the Camtable Length

value.

68

Get

Cam Input

Velocity

REAL

4

cnts/ sec

The current master velocity value.

69

Get

Cam Current

Position

DINT

4

cnts

The output position of the cam. This position

always corresponds to the output position

defined for the given “Input Position” in the cam

table.

If the cam ends at a non-zero output position, this

value will roll back to zero (where all cams start),

and the Cam Offset status will be incremented by

the difference between the starting and stopping

output positions for the cam table.

The actual position command generated by the

cam is the sum of the Cam Offset and Cam

Current Position.

70

Get

Cam Current

Velocity

REAL

4

cnts/ sec

The actual velocity command generated by the

cam. This value will be equal to the Cam Input

Velocity multiplied by the instantaneous cam

table velocity, which is the rate of change of the

cam position.
