● Homing or adjustment
– Setting reference point (with stationary axis)
– Homing
(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)")
– Flying referencing
(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".
– Homing with incremental measuring systems
– Absolute encoder adjustment
● Traversing blocks mode (64 traversing blocks)
– Positioning by means of traversing blocks stored in the device, including continuation
conditions and specific jobs for previously homed axis
– Traversing block editor using STARTER
– A traversing block contains the following information:
Job number
Task (e.g. position, wait, GOTO set jump, set binary outputs)
Motion parameters (target position, override speed for acceleration and deceleration)
Mode (e.g.: skip block, continuation conditions such as "Continue_with_stop" and
"Continue_flying")
Job parameters (e.g. wait time, block step conditions)
● Direct setpoint specification mode (MDI)
– Positioning (absolute, relative) and setting-up (endless closed-loop position control)
using direct setpoint inputs (e.g. via the PLC or process data)
– It is always possible to influence the motion parameters during traversing (on-the-fly
setpoint acceptance) as well as on-the-fly change between the Setup and Positioning
modes.
● Jog mode
– Position-controlled traversing of the axis with the switchable modes "Endless position-
controlled" or "Incremental jog" (to traverse an "increment")
● 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.
Commissioning
The "basic positioner" function module can be activated by running the commissioning
Wizard. Parameter r0108.4 indicates whether the function module has been activated.
