Control card, USB serial communication:
USB standard 1.1 (Full speed)
USB plug USB type B “device” plug
Connection to PC is carried out via a standard host/device USB cable.
The USB connection is galvanically isolated from the supply voltage (PELV) and other high-voltage terminals.
The USB ground connection is
not galvanically isolated from protection ground. Use only an isolated laptop as PC connection to the USB connector on
the adjustable frequency drive.
