I am looking at the possibility of retrofitting an anilam system to Mach. The system right now is 110vdc brushed servo, I think 10amps max. What is it that dictates the 80volt max? I guess it seems like an odd place to stop when 110 is easy to come by.
If I were to use the G320, I would have to step the voltage down. Does anyone think performance would suffer?
Thanks,
Joe

The power MOSFET transistors used in the G320 are rated for 100 volts maximum.

The G320 is rated at 80 volts in order to allow a little room to spare for safety.

Using a lower voltage will result in the maximum speed of your servo motors
dropping almost in direct proportion to the reduced voltage. The available
torque is not significantly affected. For many applications the reduction in
maximum speed is an acceptable compromise.

This is a longshot, could there be an option to order with a higher rated transistor?
I would rather spend more on the drive than add a transformer.

The usual design criteria to get optimum performance from the servo's, the power supply voltage should be designed for at least 10% above the motor rated voltage.
And of course the drive have to be this capable.

Looks like I may be better off using the original drives and working on the interface between step-direction and analog.
