7.8 Connections.
7.8.1 Ground connection.
Connect the CNC ground terminal to the main ground terminal so that the EMC performs
properly. Before connecting the inputs and outputs, make sure that the ground connection
has been made.
7.8.2 Connecting the USB2.0 port.
USB support for pen drives, hard drives, keyboards and mice; check with Fagor Automation
before connecting any other device.
Characteristics of the USB 2.0 cable.
Do not handle the connectors while the CNC is turned on (inputs/outputs, feedback, etc.). Make sure
that the device is not powered before handling the connectors.
Do not make any connections while the CNC is powered. Disconnect the power before making a
connection.
It is up to the system integrator to meet all the requirements of local and national electrical codes as
well as all the regulations applicable regarding the grounding of the whole unit.
• Do not run part programs from a USB device, whether it be when using a pendrive or external hard
drive. Fagor Automation recommends using the USB port only to exchanging data, such for
programs, reports, etc. If you require more storage space, then use a CFast disk.
• DO NOT connect any kind of hub to the USB port.
