Approaching a relative Cartesian position as quickly as possible

Description

The function block KRC_MoveDirectRelative executes a point-to-point motion to a relative Cartesian end position. The parameter “Position” contains the path from the current position to the end position. This corresponds to a PTP_REL motion on the robot system.

Approaching a relative Cartesian position as quickly as possible 1:

This statement always refers to the current position of the robot. If the motion is interrupted and then re-executed, the robot executes the entire motion again, starting from the position at which it was interrupted.

Approaching a relative Cartesian position as quickly as possible 2:

If the motion is executed as a spline motion, the following must be taken into consideration: If the motion is approximated and there is no further motion instruction in the buffer, the output “Done” is not set for the spline motion. In this case, the motion is not ended at the end point, but at the approximate positioning point.

Inputs

Parameter

Type

Description

AxisGroupIdx

INT

Index of axis group

  • 1 … 5

ExecuteCmd

BOOL

Starts/buffers the motion in the case of a rising edge of the signal.

Position

E6POS

Distance between end position and current position. The end position is based on the current position.

(>>> E6POS)

The data structure E6POS contains all components of the end position (= position of the TCP relative to the origin of the selected coordinate system).

Note: If the value -1 is transferred for Status and Turn, the shortest path to the end position is taken.

Velocity

INT

Velocity

  • 0 … 100%

Refers to the maximum value specified in the machine data. The maximum value is dependent on the robot type and refers to the value of DEF_VEL_CP of the robot system.

Default: 0% (= velocity is not changed)

Acceleration

INT

Acceleration

  • 0 … 100%

Refers to the maximum value specified in the machine data. The maximum value is dependent on the robot type and refers to the value of DEF_ACC_CP of the robot system.

Default: 0% (= acceleration is not changed)

CoordinateSystem

COORDSYS

Coordinate system to which the Cartesian coordinates of the end position refer

(>>> COORDSYS)

Approximate

APO

Approximation parameter

(>>> APO)

BufferMode

INT

Mode in which the statement is executed

  • 1: ABORTING
  • 2: BUFFERED

(>>> BufferMode)

SplineMode

BOOL

TRUE = motion is executed as a spline motion.

FALSE = motion is executed as a conventional point-to-point motion.

Outputs

Parameter

Type

Description

Busy

BOOL

TRUE = statement is currently being transferred or has already been transferred

Active

BOOL

TRUE = motion is currently being executed

Done

BOOL

TRUE = motion has stopped

Aborted

BOOL

TRUE = statement/motion has been aborted

Error

BOOL

TRUE = error in function block

ErrorID

DINT

Error number
