The Global Drive Control easy parameterisation
software must be installed on your PC.
1. Connect communication module to the PC via
PC system cable 1.
2. Insert the connecting cable 2 into the
diagnosis terminal.
3. Remove protective cap 3 from the motec
heatsink.
4. Connect connecting cable 2 to the interface
(AIF) of the controller.
When the mains voltage is switched on, the
communication module is ready for operation. You
can communicate with the drive.
Tip!
The controller has a double basic insulation to EN 50178. An additional electrical isolation is
not required.
Use the Lenze accessories listed for wiring.
