Measuring Input TO - Part III

Overview of Measuring Input TO

5.1.1

General information about the Measuring Input TO

The Measuring Input technology object is used for fast, accurate measurement of actual 

positions. This is achieved with hardware support (e.g. measuring input on the associated drive 

unit).     
Measurement jobs are activated and configured using the functions of the Measuring Input TO.

Local and global measuring inputs
Depending on the hardware platform, local and global measuring inputs are available for the 

measuring tasks. Local measuring inputs are axis-related and are mainly implemented in the 

drive. The actual position value is measured.

Global measuring inputs can be freely assigned to the axes and add an internal time stamp to 

the measurement result for more precise determination of the axis positions.

Assignment to axes and encoders   
The measuring input TO can be assigned to the following axes/encoders:
● Position, synchronized, or path axes
● External encoders
● Virtual axes (only global measuring inputs)

 

 

 

Note
It is not possible to assign a measuring input to speed-controlled axes.

 

Measurement once   
A measurement job is started by a program command. When a signal edge is detected at the 

measuring input, the current position (for virtual axes, either setpoint or actual value, as 

required) is stored temporarily. When the current system cycle clock finishes (either Servo 

cycle clock or interpolator cycle clock), this value is available in a system variable for further 

processing in low-priority tasks.

Cyclic measurement (global measuring inputs only)   
A measurement job is started by a program command. Up to two edges can be detected for 

each processing cycle clock of the measuring input TO (with onboard measuring inputs of 

SIMOTION D, CX32, CX32-2, CU310, CU310-2, CU320, CU320-2 max. of two edges for every 

three position control cycle clocks). These are stored in system variables and remain available 

until they are overwritten by more recent measurements. The measured values are detected 

continuously/cyclically until the program command is deactivated. Cyclic measuring is only 

possible with global measuring inputs.
