USB powered drive
The Nix can be powered from USB for configuration purposes
without the need of an external power supply.
With USB supply the Nix is not capable of driving a motor, but communications, feedbacks and IOs are fully
functional. An internal switch automatically chooses the power source prioritizing the Supply and shunt
connector. Please note that several functionalities will not be available when powered from USB.
USB wiring recommendations
Although USB is a widespread communication standard it has some disadvantages when operating in noisy
environments. Following are some wiring recommendations.
• Use shielded cable with the shield connected to PC end. Shield of micro USB connector is
not
connected on
Nix.
•
Do not rely on an earthed PC to provide the Nix Servo Drive earth connection. The drive must be earthed
through a separate circuit.
• Avoid creating ground loops by using isolated power supplies.
• Shortest cables are preferred.
USB application
USB interface is only recommended for configuration purposes. For noisy environments, CANopen
interface is strongly recommended.
