PROFIdrive
PROFIdrive is a profile specified by the PNO (PROFIBUS user organization) for
PROFIBUS DP and PROFINET IO for speed- and position-controlled drives.
PROFIdrive frame
Frame for communication according to PROFIdrive.
Proximity switch
Position switch which is activated with the moving part without mechanical contact.
Restart
The technology object is reinitialized with the current configuration parameters.
Software limit switch
A programmable position which limits the traversing range of an axis.
Synchronous operation
Defined movement of a following axis to a leading axis.
Technology data block
The technology data block represents the technology object and contains all configuration
data, setpoint and actual values, and status information of the technology object.
Technology interrupt
If an error occurs at a technology object (e.g. approaching a hardware limit switch), then a
technology interrupt is triggered and indicated.
The impact of a technology interrupt on the technology object is specified by the interrupt
reaction (e.g. remove enable). The interrupt reaction is specified by the system.
Technology module (TM)
Module for technological tasks, e.g. counting, measuring and positioning.
Zero mark
Position reference for the movement of rotary and linear incremental encoders. The zero
mark of an incremental encoder is used as a homing mark, for example.
