I do but it's not uncommon that people ask for 200V/25A drives on the Mach3 list for example. With Rutex currently in a somewhat unknown state and the Pixies S/D->analog converter being discontinued you really don't have many options when it comes to driving larger servos. |
Larkens Viper 200 drives will drive motors up to 170 volts and 20 amps. This is a DC servo drive, not an ac servo drive though.
