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 connection is
not galvanically isolated from protection earth. Use only isolated laptop/PC as connection to the USB connector
on frequency converter or an isolated USB cable/converter.
