Typical applications
What a motion controller is
A motion controller plans and coordinates movement for one or more axes, sending position, velocity or torque commands to servo or stepper drives. It generates trajectories with defined acceleration and jerk, synchronises axes for interpolation, electronic gearing and camming, and handles homing, limits and registration inputs. Commands reach drives over pulse, analogue or, most commonly now, EtherCAT and other real-time networks. Many controllers also include PLC functions to IEC 61131-3, combining logic and motion.
When engineers choose a motion controller
Choose a dedicated motion controller when a machine needs coordinated multi-axis motion beyond basic point-to-point moves, such as robots, gantries, packaging and CNC. It gives deterministic timing and motion libraries. The trade-offs are cost, programming effort and ecosystem lock-in. For simple machines with a few independent axes, a PLC with motion function blocks or intelligent drives with stored moves may be enough.
How to specify the Delta Electronics AX-8 motion controller
Send these with your enquiry and an engineer can confirm the right AX-8 motion controller variant or an equivalent:
- Number of axes and drives
- Network and cycle time (ms)
- Motion functions: interpolation, camming, robotics
- Programming environment and languages
- I/O and expansion
- HMI and connectivity
- Safety integration
Common mistakes to avoid
- Choosing a controller that does not support the drives' network
- Underestimating cycle time needs for many axes
- Ignoring programming tools and skills in the team
- Not planning for future axis count
Delta Electronics AX-8 motion controller: frequently asked questions
Can you help replace Delta Electronics AX-8 motion controller or source the original?
Send the full model code, quantity and required date. Our engineers can check original-part availability and assess suitable alternatives, including Motion Control Products options where appropriate. We confirm compatibility and any changes needed before recommending a replacement.
What is the Delta Electronics AX-8 motion controller?
PC-based CODESYS motion controller on an Intel Celeron J1900 quad-core, controlling up to 64 EtherCAT axes with a 1 ms synchronous cycle for 64 real and virtual axes. Published series figures include axes 64. It is made by Delta Electronics, Inc.; Specify Motion can help source it or propose an equivalent.
Who makes the Delta Electronics AX-8 motion controller?
The Delta Electronics AX-8 motion controller is made by Delta Electronics (Delta Electronics, Inc.) and is listed here for engineers comparing options. Specify Motion is not affiliated with Delta Electronics, Inc.; brand names are used only to identify the product.
What is the axes of the Delta Electronics AX-8 motion controller?
The published series maximum axes is 64. Individual models and sizes in the AX-8 motion controller range vary, so check the exact variant against your duty cycle, mounting and environment, or ask our engineers to confirm the right size for you.
Is there an alternative to the Delta Electronics AX-8 motion controller?
We can assess suitable replacement options. Our engineers can review the original model and propose options for your load, speed and environment. An engineer confirms the fit against your application before recommending anything.
What is the difference between a motion controller and a PLC?
A PLC handles machine logic, sequencing and I/O. A motion controller specialises in trajectory planning and coordinating axes. Many modern controllers combine both, running PLC logic and motion libraries on one CPU. Choose based on axis count, motion complexity and timing requirements.
Why is EtherCAT common for motion control?
EtherCAT offers short cycle times, precise synchronisation using distributed clocks and simple cabling, which suit coordinated multi-axis motion. Many drives and I/O devices support it. Other real-time networks such as PROFINET IRT and Sercos are also used, so check what the drives and controller support.
