3.4.4 PosiCon I/O special extension
(SK XU1-POS, part no.: 278200130)
The Posicon I/O special extension (E
X
tension
U
nit) provides a posi-
tioning control system designed for integration into the inverter.
Based on distance and speed calculations, the loads are moved pre-
cisely and dynamically to pre-programmed positions.
Position sensing is ensured by means of an incremental encoder
(RS422) and/or an absolute value encoder (SSI protocol).
The encoders may be installed either on the motor or on the load.
Gear ratios are adjustable as required.
