3.2.6 Profibus module, SK TU3-PBR, …-24V
A large number of different automation
devices can exchange data using Profibus.
PLC's, PC's, operating and monitoring
devices can all communicate via a uniform
bus in serial bit mode.
Data exchange is specified in DIN 19245
Part 1 and 2 and application specific
upgrades in Part 3 of this standard. Within
the European field bus standardisation
process, Profibus is integrated into the
European field bus standard pr EN 50170.
The termination resistor for the last bus
participant is located in the Profibus
standard plug.
The module SK TU3-PBR does not require
an external supply voltage, as it is supplied
internally by the frequency inverter. Therefore, bus communication is only possible if the frequency inverter is
connected to the mains.
The module SK TU3-BPR-24V requires an external 24V supply, and is therefore operable even if the
frequency inverter is not connected to the mains. The module has a current consumption of approx. 80mA.
Detailed information can be found in the operating instructions

or contact the supplier of the
frequency inverter.

3.2.7 CANopen module, SK TU3-CAO
The CANopen interface on the NORDAC frequency inverter enables the
parameterisation and control of the devices in accordance with standardised
CANopen specifications
Up to 127 participants can be addressed on a single Bus. A termination
resistor is integrated and can be switched on.
The transfer rate (10kBaud and 500kBaud) and the Bus addresses are set
using rotary coding switches or the applicable parameters.
