2.2 Posicon I/O connection
The Posicon I/O special extension module (also referred to as XU,
EXtension Unit) is a system of positioning control for integration
into the frequency inverter. The positions which have been
programmed in advance will be exactly and dynamically
appproached on the basis of distance calculation.
Positions are captured by means of an incremental encoder and/or
an absolute value encoder.
The encoders may be installed either on the motor or on the load.
Step-up or step-down ratios can be adjusted at discretion.
Maximum connection cross section of the control lines:
Connector Functions Maximum cross section
X10.1 Output relay 1.0 mm 2
X10.2 Digital inputs 1.0 mm 2
X10.3 SSI input 1.0 mm 2
X10.4 Incremental encoder input 1.0 mm 2
PLEASE NOTE: All of the control voltages are related to the same reference potential!
The total allowable current rating of all individual power sources put together will be = 300mA max.
