Time Lock CAM

The Time Lock Cam block executes a time-lock cam profile created by a
previous Configure Cam block, on the selected servo or imaginary slave
axis, in the selected direction. Time-lock cams allow the execution of
motion profiles other than trapezoidal, S-curve, or parabolic. No
maximum velocity, acceleration, or deceleration limits are used for time-
lock cams. The speed, acceleration, and deceleration of the slave axis are
completely determined by the profile stored in the cam tables.

The Time Lock Cam block resides on the Cam Palette.

While a time-lock cam is in progress:

TCAM_status = 1 (true)

Axis_status = 3 (Executing Time-lock Cam)

Lock_status = 0 (Unlocked)

When the cam is done:

TCAM_status = 0 (false)

Axis_status = 1 (Unlocked)

When the cam is done and the position error of the axis is less than the
position lock tolerance:

Axis_status = 0 (Locked)

Lock_status = 1 (Locked)
