SYSTEM CONNECTION DIAGRAM

The system consists of controller, motor systems, encoder, power supply units and safety ele-

ments is wired as shown below (schematically shown)..

Encoders and motor drivers can be connected directly with patch cables as well as with mul-
ti-core cables. Driver error outputs can be connected to the error input. Please observe the
