Yes, that's right.

OK, the drive is a "dumb" amp, takes in PWM and puts out voltage
proportional to the PWM percentage.
So, it needs a controller. My Universal PWM Controller handles up to 4
axes, and reads the encoder itself.
It can handle up to 300,000 encoder counts a second (actually a bit
more). It is supported by EMC2.

I know Gidding & Lewis Centurion motors work well. I haven't tried it
with Panasonic motors in this class, but it works great with the
Panasonic MUMS082 motor, which is 750 W. They have larger models.
