Product Description
Autoblocks Absolute Motors
Absolute position. Absolute control. Absolute scalability.
The Autoblocks Absolute Motor is the most capable integrated stepper on the market today — and the only one engineered to deliver true absolute performance across every dimension that matters. Absolute position, from the moment power is applied, with no homing routine to write or run. Absolute control, with drive, motion controller, and encoder integrated directly into the motor. And absolute scalability, with up to ten motors daisy-chained on a single M12 bus and coordinated motion handled across the network — no external drivers, no motion controller cards, no cabinet rebuilds.
For machine builders, this is not an incremental upgrade to a stepper line. It is the architectural shift the category has been waiting for.
A complete motion node, in a single package
Every Autoblocks Absolute Motor combines four components that traditionally live in four different parts of a machine:
Closed-loop stepper motor — high-resolution, high-torque performance with the precision of a servo and the predictability of a stepper. No tuning, no surprises.
Integrated drive — eliminates cabinet drives, separate power supplies, and the cable runs that connect them. Reduces cabinet footprint, BOM cost, and points of failure in equal measure.
Integrated motion controller — coordinated multi-axis motion is computed across the bus, not in a central controller card. This is the architectural shift that lets Autoblocks systems scale linearly with axis count.
Absolute encoder — the machine knows where every axis is the moment power is applied. No homing routines. No re-indexing after an E-stop. No position drift across power cycles.
An optional integrated programmable brake is available for vertical or load-holding applications, configured directly through AutoCode without external relay logic.
Scales without external drivers or motion controllers
A single M12 cable delivers both power and communication to every motor. Up to ten motors daisy-chain on any Autoblocks system, governed by the Control Block, with full coordinated motion across all of them.
The implications are not subtle:
- No drive cabinet. No drive cards. No motion controller cards.
- Adding a sixth, seventh, or tenth axis is a mechanical decision, not an electrical redesign.
- Cable count, cable management, and cabinet cooling load drop dramatically.
- Replication is trivial — every machine is wired the same way, regardless of axis count.
For OEMs and integrators delivering to production environments, this translates directly into shorter build cycles, smaller cabinets, lower BOM cost, and dramatically simpler field service.
Configured and running in minutes
Pair an Autoblocks Absolute Motor with a Control Block and AutoCode, and any axis — including a fully coordinated multi-axis group — can be configured and running in minutes. AutoCode is there when the application calls for custom kinematics, conditional motion, or external coordination.
There is no per-axis tuning ritual. There is no homing routine to write. There is no separate motion controller to program. The motor is its own controller, and the platform handles the rest.
Frame size for every application
Available in five frame sizes, every motor in the line shares the same architecture, the same communication protocol, and the same AutoCode configuration model — so engineering effort transfers directly across applications.
| Frame | Typical applications |
|---|---|
| NEMA 8 | Micro-positioning, optical alignment, lab automation, small medical-device assembly |
| NEMA 11 | Compact dispensing, microfluidics, light pick-and-place, instrument actuation |
| NEMA 17 | General-purpose linear and rotary axes, light gantries, conveyor indexing |
| NEMA 23 | Mid-range gantries, SCARA configurations, dispensing and inspection cells |
| NEMA 34 | High-torque applications, vertical lift axes, heavy-duty industrial actuation |
Every motor is fully interchangeable across the platform. There is no separate driver SKU to match, no firmware variant to track, and no application-specific commissioning required.
Built to work as one with the Autoblocks platform
The Absolute Motor line is engineered as a peer component to the rest of the Autoblocks system — not as a third-party module integrated after the fact.
With the Control Block — auto-detected on the bus, configured visually, coordinated natively. No hand-mapping of axes, no driver-specific setup.
With the Pendant — every axis is jog-able, teach-able, and diagnosable from the moment it’s connected. Position feedback is live and absolute.
With AutoCode — every motor capability, including coordinated motion across multiple axes, is exposed through the same language as the rest of the machine. No second SDK. No second mental model.
Where they are used
Autoblocks Absolute Motors are deployed across precision assembly, electronics manufacturing, automotive subsystem production, medical device assembly, dispensing, inspection, and high-mix industrial automation. They power everything from single-axis indexing applications to fully coordinated SCARA and gantry robotics — without changing the underlying control architecture.
