Eg Control - Omron TJ1-DRT Hardware Reference Manual

System philosophy
Circular interpolation
It may be required that a tool travels from the starting point to the
end point in an arc of a circle. In this instance the motion of two
axes is related via a circular interpolated move using the
MOVECIRC command.
Consider the diagram in the figure. It corresponds to the
MOVECIRC(-100,0,-50,0,0) command. The centre point and
desired end point of the trajectory relative to the start point and the
direction of movement are specified. The MOVECIRC command
computes the radius and the angle of rotation. Like the linearly
interpolated MOVE command, the ACCEL, DECEL and SPEED
variables associated with the base axis determine the speed profile
along the circular move.
CAM control
Additional to the standard move profiles the TJ1-MC__ also
provides a way to define a position profile for the axis to move. The
CAM command moves an axis according to position values stored
in the TJ1-MC__ Table array. The speed of travelling through the
profile is determined by the axis parameters of the axis.
The figure corresponds to the command CAM(0,99,100,20). A is
the time axis, B is the position axis.

EG control

Electronic Gearing control allows you to create a direct gearbox link
or a linked move between two axes. The MC Unit supports the
following operations.
• Electronic gearbox
• Linked CAM
