ET_PosMode - General Information

Overview

Type:	Enumeration
Available as of:	V1.0.0.0

Description

The enumeration ET_PosMode specifies the positioning modes for the movement of the carrier.

For a visual illustration of the positioning mode options, refer to the video sequences accessible via the table below.

Enumeration Elements

Name	Value (INT)	Description
Relative	0	Relative positioning of the carrier in relation to its actual position.⁽¹⁾ NOTE: This positioning mode is only allowed for the move command MoveDirectly (see MoveDirectly – Start).	Relative
Absolute	1	Absolute positioning of the carrier.⁽¹⁾ The movement direction depends on the target position (in mm) on the track: If the target position has a higher value than the actual position, the carrier moves in forward direction. If the target position has a lower value than the actual position, the carrier moves in backward direction. NOTE: This positioning mode is only allowed for the move command MoveDirectly (see MoveDirectly – Start).	Absolute
AbsoluteForward	2	Absolute positioning of the carrier in forward direction.⁽²⁾	AbsoluteForward
RelativeForward	3	Relative positioning of the carrier in forward direction.⁽²⁾	RelativeForward
AbsoluteBackward	4	Absolute positioning of the carrier in backward direction.⁽²⁾	AbsoluteBackward
RelativeBackward	5	Relative positioning of the carrier in backward direction.⁽²⁾	RelativeBackward
(1) In this positioning mode, the parameter i_lrTarget is not limited to the track length as specified by the parameter lrTrackLength when the track in question is a closed track. (2) In this positioning mode, the parameter i_lrTarget is limited to the track length as specified by the parameter lrTrackLength. For more information on the track length, refer to lrTrackLength.
