3.3.1 PosiCon I/O
(SK XU1-POS, Option)
The special extension unit (EXtension Unit) PosiCon I/O is a positioning control
system 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,
specially produced for this option.

WARNING / NOTE
It is not permissible to connect the output relay of the Customer Unit (SK CU...and SK XU) to dangerous
voltages(
≥60VAC) if a contact of the relay is connected to a circuit with safe isolation.
