Can a general statement be made about which draws more amperage digital or analog?
Or it is it more a question of torque and speed?

Thanks.

The amplifier in a digital servo updates the motor position many more times per second than an analog amp, also full torque is realized almost instantly on a digital where a standard servo needs to be something like 10 degrees away from its commanded position for max torque. All that comes at the expense of increased power consumption.

Thanks for that info.
Makes sense and was along the lines of my thinking.
I appreciate the detailed explanation.
