3.4.4 Special Extension PosiCon I/O
(SK XU1-POS, Part No.: 278200130)
The special extension unit (EXtension Unit) PosiCon I/O is a
positioning control system which is integrated in the frequency
inverter.
Previously programmed positions are reached
dynamically and precisely by means of path calculations.
The position acquisition is implemented by an incremental
(RS422) or absolute encoder (SSI protocol).
The encoder can be fitted on the motor or the load, step-up/step-
down can be freely selected.
Note:
Further details can be found in the operating
instructions BU 0710, which were specially produced
for this option.
