Graphic expression AOI category
Motion

Input and Output Variable

Variable name Data type Valid range Conditions for Input and Output
AxesGroup eRC_AxesGroup -
Robot group
Specify a robot variable (structured type data : eRC_AxesGroup) of user-defined type.
ExtAxPosition eRC_Joint For input
Target position of extended-joint
Specify the target position of extended-joint in Joint coordinate (Joint type). Unit is degree.
For 4-axis robot: J5 to J8 are available.
For 6-axis robot: J7 to J8 are available.
For both 4-axis and 6-axis robots, if Joint settings of extended-joint is disabled, this variable is not available.

If the target value is entered in an element that does not exist in the controlled robot, the robot controller ignores the value.
For example, if any value is entered in variable "J5" to control a 6-axis robot, the robot controller controls the robot without using the value (variable J5).
CoordSystem eRC_CoordSys
  • Tool : 0 to 63
  • Work : 0 to 7
 For input
Target position
Specify the tool coordinate system and the work coordinate system used when making the robot motion with a coordinate number.
In addition to valid range values, -1 can be used.
When -1 is specified, the robot motions at the coordinate system currently set.
For example, if -1 is set to the variable "Tool", the robot motions at the tool coordinate system of the tool number currently set.

Input Variable

Variable name Data type Valid range
Execute Boolean
  • TRUE : Start
  • FALSE : -
Execution start
When the variable is changed from FALSE to TRUE, this AOI is executed.
DeparthLen Real -
Depart length
Specify an depart length. Unit is millimeter.
Velocity Real 0.1 to 100.0
Internal speed
Specify the internal speed used when moving to the target position. The unit is "%".
In addition to valid range values, -1 and 0 can be used.
-1 : The robot moves at the current internal speed.
0 : The minimum valid range value "0.1" is applied.
Acceleration Real 0.0001 to 100.0
Internal acceleration
Specify the internal acceleration used when moving to the target position. The unit is "%".
In addition to valid range values, -1 and 0 can be used.
-1 : The robot moves at the current internal acceleration.
0 : The minimum valid range value "0.0001" is applied.
Deceleration Real 0.0001 to 100.0
Internal deceleration
Specify the internal deceleration used when moving to the target position. The unit is "%".
In addition to valid range values, -1 and 0 can be used.
-1 : The robot moves at the current internal deceleration.
0 : The minimum valid range value "0.0001" is applied.
BufferMode Integer 0, 1, 6, 7, 8, 9
Buffer mode selection
Specify how to connect motions when this AOI is executed when the robot is in motion.
The process flow of each buffer mode is as follows:
[0 : Aborting OP0]
  1. The robot decelerates at 100% deceleration.
  2. The robot stops (End motion)
  3. This AOI motion is executed.
[1 : Buffered]
  1. The robot moves to the current target position.
  2. The robot stops (Encoder value check motion (Axes coordinate system)).
  3. This AOI motion is executed.
[6 : Blending]
  1. The robot moves to the vicinity of the current target position.
  2. The robot executes the motion end method specified in the input variable "TransitionMode".
  3. This AOI motion is executed.
[7 : Aborting OP1]
  1. The robot decelerates at 100% deceleration.
  2. The robot does not stop (Pass motion).
  3. This AOI motion is executed.
[8 : Aborting OP2]
  1. The robot decelerates at the current deceleration.
  2. The robot stops (End motion).
  3. This AOI motion is executed.
[9 : Aborting OP3]
  1. The robot decelerates at the current deceleration.
  2. The robot does not stop (Pass motion).
  3. This AOI motion is executed.
TransitionMode Integer 0, 3, 10, 11
Transition mode selection
Specify how to end the current motion when "6 : Blending" is selected in the input variable "BufferMode". The end method for each value is as follows:
[0 : The robot stops (Encoder value check motion (Axes coordinate system))]
[3 : The robot does not stop (Pass motion of distance designation)]
If 3 is selected, specify a distance to start the pass motion in the input variable "TransitionParameter".
[10 : The robot does not stop (Pass motion)]
[11 : The robot stops (Encoder value check motion (Cartesian coordinate system))]
TransitionParameter Integer 0 to 32767
Target position
Specify a distance to start the pass motion when "3 : The robot does not stop (Pass motion of distance designation)" is selected in the input variable "TransitionMode". Unit is millimeter.
When the distance between the robot position and the current target position is below the value of this variable ("TransitionParameter"), the pass motion starts.

Output Variable

Variable name Data type / Description

TRUE : This AOI execution is completed.
FALSE : This AOI execution is not completed.
NextActionPermit Boolean
Next motion permission
This variable indicates whether or not another AOI is allowed to be executed.
TRUE : Execution allowed.
FALSE : Execution not allowed.
To connect this AOI motion to the next AOI motion, enter this variable ("NextActionPermit") in the input variable "Execute" of the next AOI.

This is a number to identify the error description.
For details, refer to "Error code list".

Function Description

About PTP control
PTP (Point to Point) can be defined as the movement from one point to another point. The path on which the robot moves depends on the robot posture and is not always a straight line.
The figure below shows an example of motion by PTP control.

Attention

To execute this AOI, AOI with the AOI category "Motion" needs to be made executable.
To make AOI with the AOI category "Motion" executable, use the AOI "MC_Power".
