FAQ

Q:Does VENZO 800 can do 2-axis control? How?

A: Absolutely yes, but you should choose model 880. In normal configuration, VENZO 880 only has one drive channel and one AUX channel, if customer needs MIMO control, we will change AUX channel to drive channel, this does not means changes in hardware, you just need our MIMO control software.


Q:Does VENZO 880 Vibration Controller have grounding problem?

A: No. Because VENZO 800 Vibration Controller series adopts 100 Mbps Ethernet pot connected to PC, also the hardware is floating ground design which reduces ground loop problems.
