HuanYang uses a module for the high power stage, most of the cheap ones are
using discretes.

Dunno why Sony quit the AIBO and QRIO robots. AIBO dog was only sold in limited

I usually include a input power line filter on servo and VFD
applications if there is a computer or PLC involved. I've done a few
machines without drive input filters and noise problems have bit me.
Fixing the problem after the fact costs more in wasted time than the
cost of the filter/s.

It _should_ read PD143, so the first question is

So the next dance might be Korean.
Or, they might learn Taekwondo.

I saw this shortly after it came out. At the time I wondered if they
were using hydraulics on Atlas. At one point you can see what looks
suspiciously like some liquid was spilled on the floor. Looks like one
of the robots sprung a leak during testing.
Incredible motion control. They've come a

Hi John,
You've got me a bit interested in these drives. I'm currently looking for
the biggest single phase servo I can easily find, looks like the Bergerda
1.8 or maybe even 2.6kw might be it. But it's always a bit hard to tell
with the lower quality documentation these companies provide.
Input line filters are suggested for a lot of systems that might emit noise
back into the power line.

Hey Gene,
I would agree - output filters on a VFD would not be a good idea. I was
thinking of Input Line filters to the VFD. If I recall, the VFD can send
back noise on the input lines which can be picked up by other stuff, either
power supplies, computers, or I/O points and cause issues.
