The compliance with the requirements for the multi−axis
grouping with power supply module and for the
machine/plant is the responsibility of the manufacturer of
the machine or plant.

DC voltage symmetrical to PE required.
Earthing of +UG/−UG conductor will destroy the axis
modules.
Motors Only use motors suitable for inverter operation. L−force
motors from Lenze meet the requirements.
