The Commander core is designed to be a master controller for both stepper and digital servomotors and their drivers.  There are a few differences between how a stepper and a servo system react and the connections needed between the Commander core and their respective drivers.

The difference between a stepper motor and a servomotor configuration is shown in the following subsections. The design and construction of the motors are also different. Stepper motor operation is synchronized by command pulse signals output from a pulse generator (strictly speaking, it follows the pulses). In contrast, a servomotor will translate the command pulse signals into speed, direction, and distance commands (usually one pulse equals one encoder pulse); as such the servomotor operation lags behind the command pulses.
