Control card performance
Scan interval 5 ms
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 earth. Use only an
isolated laptop as PC connection to the USB connector on the frequency converter.
