Position Point

Provides the position error from one or many preset positions. Use with linear or cyclic position blocks to define particular positions within them.

Freely define up to 100 indexed position points. The position points may be pre-programmed by the engineer using the savvy software either manually or via .csv file import or text import from another block. Position points may also be defined automatically; The motor is moved to the index position and stopped. The Set parameter is toggled Active and then Inactive to set the position of that index.

Design a complete motion control solution with three function blocks. The following pictures show examples of Position Point function block in two different systems. The systems allow up to 100 positions to be pre-defined and selected via an index.

• Available only in the dw2xx-v2 series products
• Requires library: Precision Motion (option -39)
• Firmware versions 0x2105 and later

Position

Designed to be directly connected from the output of a Linear Position or Cyclic Position function block. That block defines the position scaling and zero point.

Position Error

The position error from the indexed position. Typical connects directly to the input of Trapezoid Motion v2 function block.

Set

Used for in-position setting of any of the indexed position points.

The motor is moved to the required, indexed position and the Set parameter is momentarily asserted.

Index

Freely define up to 100 indexed position points. The position points may be pre-programmed by the engineer using the savvy software either manually or via .csv file import or text import from another block.

Index points may also be defined automatically; The motor is moved to the index position and stopped. The Set parameter is toggled Active and then Inactive to set the position of that index.

Program

Click this parameter for the position point editor.

Manually enter position points or import/export from .CSV file which is easy to use with spreadsheets, etc.
