Functions, monitoring and protective functions
9.4 Extended functions
● Homing or adjustment
– Setting reference point (with stationary axis)
– Homing
– Flying referencing
– Homing with incremental measuring systems
– Absolute encoder adjustment
● Traversing blocks operating mode
– Positioning by means of traversing blocks stored in the device, including continuation
– Traversing block editor using STARTER
– A traversing block contains the following information:
● Direct setpoint specification mode (MDI)
– Positioning (absolute, relative) and setting-up (endless closed-loop position control)
– It is always possible to influence the motion parameters during traversing (on-the-fly
● Jog mode
– Position-controlled traversing of the axis with the switchable modes "Endless position-
● Standard PROFIdrive positioning telegrams are available (telegrams 7, 9 and 110), the
selection of which automatically establishes the internal "connection" to the basic
positioner.
● Control using PROFIdrive telegrams 7 and 110.

(separate mode including reversing cam functionality, automatic reversal of direction,
homing to "cams and encoder zero mark" or only "encoder zero mark" or "external
zero mark (BERO)")
(superimposed homing possible during "normal" traversing with the aid of the
measurement probe evaluation (normally evaluation of a BERO, for example).
Superimposed function for the modes "Jog",
" Direct setpoint specification / MDI" and
"Traversing blocks".
conditions and specific jobs for previously homed axis
- Traversing block number
- Task (e.g. positioning, wait, GOTO set jump, set binary outputs)
- Motion parameters (target position, velocity override for acceleration and
deceleration)
- Mode (e.g.: skip block, continuation conditions such as "Continue_with_stop" and
"Continue_flying")
- Task parameters (e.g. wait time, block step conditions)
using direct setpoint inputs (e.g. via the PLC or process data)
setpoint acceptance) as well as on-the-fly change between the Setup and Positioning
modes.
