ETEL EA-P2M-400-5/10A-0100-01 AccurET Modular Position Controller
The ETEL EA-P2M-400-5/10A-0100-01 is a high-performance, dual-axis modular motion controller belonging to ETEL’s widely recognized AccurET Modular 400 product family.
It is engineered to control direct-drive motors with sub-micron precision, making it a staple in semiconductor manufacturing, automated optical inspection (AOI), and precision assembly systems.
This specific configuration provides a continuous current output of 5 Arms and a peak current output of 10 Arms per axis, coupled with integrated interface expansion options designed for advanced industrial setups.
Product Introduction / Overview
Designed around a highly efficient decentralized motion control architecture, the AccurET Modular platform processes complex motion profiles and path trajectories directly at the controller level.
By offloading computationally heavy operations from the host PC, it eliminates communication bottlenecks and dramatically reduces system latency.
The EA-P2M-400-5/10A-0100-01 drives two independent or highly synchronized motion axes simultaneously from a single compact hardware footprint, utilizing a shared high-voltage DC bus to optimize cabinet space and minimize wiring.

Environmental & Storage Conditions
To ensure stable operation and maintain nanometer-level repeatabilities, strict adherence to environmental tolerances is required:
Environmental Tolerance Conditions
Ambient Operating Temperature: $15^\circ\text{C}$ to $40^\circ\text{C}$ (Optimal performance envelope; continuous operation up to $50^\circ\text{C}$ is possible with proper current derating and forced-air flow).
Relative Humidity: 10% to 85% RH, strictly non-condensing.
Operating Atmosphere: Cleanroom-compatible design. Avoid environments with airborne conductive contaminants, vaporized lubricants, corrosive chemicals, or excessive structural vibrations.
Ingress Protection Level: IP20 (Designed to be built inside standard, dust-sealed industrial control cabinets).
Storage Conditions
Storage Temperature Range: $-20^\circ\text{C}$ to $70^\circ\text{C}$.
Storage Humidity Level: Under 85% RH (non-condensing).
Long-Term Storage Safety: Keep the unit in its anti-static ESD packaging inside a temperature-controlled dry environment to prevent moisture buildup on high-voltage capacitor elements.
Operating & Installation Instructions
Installation Method
Backplane Mounting: Mount the module flat against an unpainted, conductive, grounded metal machine plate using M5 screws. This guarantees electrical bonding and maximizes heat dissipation.
Clearance Spacing: Maintain a minimum clearance of 50 mm above and below the module’s cooling slots to allow convective airflow.
PE Safety Grounding: Wire the dedicated protective earth (PE) terminal to the central star ground before applying any high-voltage supply lines.
Initial Operation Steps
Auxiliary Setup: Supply the auxiliary 24 VDC power first to initialize the processor, logic board, and communication layers.
Software Connection: Connect via USB or Ethernet TCP/IP to a PC running ETEL ComET Commissioning Software.
Configuration & Autotuning: Load motor parameter files, verify feedback directions, execute phase finding, and calibrate the position loop filters.
Applying Bus Power: Once feedback is active and no active alarms remain, enable the main 100–400 VDC bus voltage.
Fault Diagnosis
Diagnose system issues using the multi-color front panel LEDs or the real-time diagnostics tab in ETEL ComET:
Overcurrent Fault / Short Circuit:
Possible Cause: Motor phase short circuit, bad cable insulation, or unstable current loop parameters.
Action: Measure phase-to-phase and phase-to-ground resistance on the motor. Run autotuning again with a lower loop gain.
Over-Temperature Alarm:
Possible Cause: Inadequate ventilation in the enclosure or driving the controller past its 5 Arms continuous thermal limit.
Action: Check internal cabinet fans and verify thermal mounting paste or conductive backplate contact.
Loss of Feedback (Encoder Error):
Possible Cause: Damaged encoder cable, high EMI noise on feedback lines, or incorrect encoder supply settings.
Action: Verify encoder cable shielding. Ensure signal lines are separated from high-power motor phases.
DC Bus Overvoltage:
Possible Cause: Regeneration energy from heavy decelerating motors without a proper braking resistor or power supply sink.
Action: Verify the power supply regenerative limit or add/upgrade the external braking unit.
