Choosing between a stepper motor and an AC servo driver is easier when you separate the two halves of a motion axis. In the servo stepper motion control category, these two components are often mentioned together even though they perform separate jobs. The Schneider Electric LMHAE572C is a stepper motor. The Omron R7D-ZP02H is an AC servo driver. Both are industrial motion control parts, but one belongs on the moving side of the axis and the other on the drive side. Pick the wrong one and your build will have a motor where you need a driver, or a driver where you need a motor.
Quick Verdict
If your priority is a lower listed price and you need an AC servo driver, the Omron AC servo driver at $506 is the unit to go with. If your priority is a stepper motor that serves as the moving element, the Schneider Electric stepper motor at $799 is the direct match. The $293 spread between the two listed prices only matters if the lower-priced unit actually fits the role you need filled.

Where Each Product Wins
The Schneider Electric stepper motor wins when you need the moving element itself. It is the stepper motor in this comparison, while the other unit is a driver, so it is the component that would sit on the motor side of a motion axis.
The Omron AC servo driver wins when you need the drive side of a servo axis. This unit includes a Kinetix controller platform and a 325 VDC/20 Amp bus input, so it is a driver built around those particular servo-drive parameters.
Product Notes
Schneider Electric LMHAE572C Stepper Motor
The Schneider Electric LMHAE572C is the stepper motor in this pairing, so it belongs on the mechanical side of a motion axis. If your system already has a driver and needs a component that produces stepped motion, this is the unit that matches that role. It is described as brand new and unused, but it arrives without its original box, which is the main caveat to keep in mind. Its United States country of origin and Schneider Electric branding are stated up front, and the model number appears alongside the product name. This is not a servo driver, so it will not fill a drive-module position in your setup.
Omron R7D-ZP02H AC Servo Driver
The Omron R7D-ZP02H is the AC servo driver in this head-to-head. It is built for the control side of a servo motion system rather than for delivering stepped motion directly. This unit includes a Kinetix controller platform, a 325 VDC/20 Amp bus input, and Japan as its country of manufacture. Those specifics define the kind of servo-drive architecture this unit is meant for. The main limitation is the same specificity: it is a driver aimed at that platform and bus configuration, not a stand-alone motor. For the drive portion of an industrial automation project, this component fits that position.
Final Choice by Use Case
Choose the Schneider Electric stepper motor when your project calls for a stepper motor as the moving element in an industrial motion control axis.
Choose the Omron AC servo driver when your project calls for a servo driver on the control side of the axis.
