Note
-
When connecting a PC with our support software to a driver with a plus-ground connection, always use a laptop in an isolated state during the setup process.
Additionally, please disconnect the AC power supply (AC adapter) for the PC and any other devices connected via USB cable.PCs are negative grounding devices and in many cases GND and FG are not insulated.
If the PC is connected to a positively-grounded driver in this state, it may damage the PC or the driver.
(This can also cause problems in communication between the support software and the driver) - When using positive grounding, use a model that supports positive grounding not only for the driver but also for other peripheral equipment.
