I'm using their DYN4 with 400w servos on the router I'm building.
I orderd one and set it up on my test rig, and promptly blew the drive when I powered it.
I sent it to DMM and they repaired it for free, saying it blew from over voltage.
My voltage was about 245V, which falls within their specs. They sent me a tech bulletin stating to use a line reactor to smooth out the voltage. Before I test it again, I'll be getting a transformer to lower the voltage a bit.

The reason I went with the DMM is because they have good support, and are about $100/set cheaper than the cheap chinese models on Ebay and AliExpress.
Thanks. Most that are testing / using them are very happy. The software looks clean and functional too, certainly a strong contender for 'decent' servo stuff at hobby level. I bought Panasonic before for Thor however it was expensive and that was at 2nd hand / discount rates. I'd not have considered the Panasonic stuff at list prices.
