Motion Control
Cyclic Unidirectionalizer
Description

Cyclic Unidirectionalizer

Provides only positive position error outputs for cyclic position applications where the motor can only turn in one direction.

A Tolerance parameter is provided to prevent nuisance cycling when there is a small overshoot from zero position. The output is zero for inputs from -(Tolerance) to 0.0000.
Availability
  • Available only in the dw2xx-v2 series products
  • Requires library: Precision Motion (option -39)
  • Firmware versions 0x2105 and later

Parameters

Input Input, Read-write, Analog (32-bit IEEE-754 floating point value)
-0.5000 to 0.5000

Input

Designed to be connected directly from the output of the Cyclic Indexed Position or Position Point function block.
Output Output, Read-only, Analog (32-bit IEEE-754 floating point value)
0.0000 to 1.0000

Output

Provides only positive position error outputs for cyclic position applications where the motor can only turn in one direction.
Tolerance Input, Read-write, Analog (signed 16-bit integer)
0.0001 % to 3.2767 %

Tolerance

Provided to prevent nuisance cycling when there is a small overshoot from zero position. The output is zero for inputs from -(Tolerance) to 0.0000.
