ETEL EA-P2M-400-10/20A-0100-01 AccurET Modular Position Controller
ETEL EA-P2M-400-10/20A-0100-01 AccurET Modular Position Controller
The ETEL EA-P2M-400-10/20A-0100-01 (often indexed alongside its equivalent hardware revisions) is a high-voltage, high-precision dual-axis motion controller.
Operating on ETEL’s decentralized architecture, this unit is designed to drive direct-drive linear or rotary motors with sub-micron positioning resolution.
It is heavily utilized in high-duty automation, semiconductor lithography, advanced wafer inspection, and flat-panel display manufacturing systems.
The specific -0100-01 suffix signifies an integrated hardware expansion board profile—providing extra flexible input/output (I/O) lines or auxiliary feedback configurations beyond the base model.
Product Introduction / Overview
Designed around a highly responsive decentralized motion control scheme, the AccurET Modular 400 series processes complex motion trajectories and servo loops locally at the controller level rather than shifting calculations to a master computer. This reduces network latency and guarantees real-time cycle performance.
The EA-P2M-400-10/20A-0100-01 provides a continuous current output of 10 Arms and a peak current capability of 20 Arms per axis. The dual-axis design enables two separate direct-drive axes to run off a single modular unit, sharing a common DC power bus to drastically reduce cabinet space and interconnect wiring.

Product Features & Core Advantages
Uncompromising Servo Bandwidth: Operates with a 20 kHz current loop sampling time, which minimizes settling times, increases mechanical stiffness, and delivers high-performance tracking.
Ultra-Fast Nanosecond Triggers: Features position-based triggers (1D and 2D) with under 20 ns response latency, critical for fly-scan inspection systems and high-speed laser firing synchronization.
Smart Friction and Cogging Maps: Supports advanced friction compensation, look-up table mapping, and cogging torque correction directly inside the drive firmware to eliminate disturbances.
Safety Integration: Features a dedicated power safety relay that disables the output power bridge directly when safe conditions are violated.
Integrated Gantry Algorithms: Real-time synchronization for dual-motor gantry stages is handled at the hardware level via TransnET communication with negligible clock jitter.
Model Classification (Nomenclature)
The part number EA-P2M-400-10/20A-0100-01 represents a precise product configuration:
$$\mathbf{EA} – \mathbf{P2M} – \mathbf{400} – \mathbf{10/20A} – \mathbf{0100} – \mathbf{01}$$
EA: ETEL AccurET Controller Platform.
P2M: Position Controller (P), Dual Axis (2), Modular Mount style (M).
400: 400 VDC Maximum Bus Voltage capability.
10/20A: 10 Arms Continuous / 20 Arms Peak Overload output per axis.
0100: Hardware configuration code indicating a specific integrated expansion module board (e.g., additional feedback or dynamic I/O lines).
01: Revision index or customized firmware code variant.
Environmental Tolerance Conditions
To protect high-voltage switching circuits and preserve tracking repeatabilities, adhere to the following environmental limits:
Operating Temperature Range: $15^\circ\text{C}$ to $40^\circ\text{C}$ (Continuous operation at up to $50^\circ\text{C}$ is possible with proper current derating and adequate cooling airflow).
Relative Humidity: 10% to 90%, non-condensing.
Cleanroom Compliance: Cleanroom-compatible chassis. The module must be kept free of conductive dust, vaporized coolants, or corrosive atmospheres.
Ingress Protection Rating: IP20 (Must be integrated within a clean, locked electrical enclosure).
Installation Method
The modular unit is designed to be installed directly into a matching multi-axis backplane rack:
Safety Discharge Delay: Before touching any connector or sliding the module out of a rack, disconnect the 400 VDC power and 24 VDC auxiliary power. Wait a minimum of 10 minutes for the internal bulk storage capacitors to safely discharge.
Backplane Insertion: Slide the modular drive along the backplane channel guides until the heavy power pins on the rear seat completely.
Mechanical Securing: Securely tighten the front panel integration screws into the rack chassis. This establishes the primary low-impedance safety earth connection.
Thermal Dissipation: Ensure a minimum of 50 mm clearance is left open at the top and bottom of the cooling vents for adequate airflow.
Operating Instructions & Commissioning
Auxiliary-First Sequence: Always apply the auxiliary 24 VDC control power first. This initializes the internal CPU, digital logic, safety state-machines, and communication layers before high voltage is present.
Software Communication: Establish communication with a host PC using the ETEL ComET Commissioning Software over USB or Ethernet.
Parameter Setup: Load the appropriate motor parameter file (.prs clone file format), execute the phase finding sequence, and calibrate position feedback.
Primary Bus Initialization: Once feedback is stable and no active errors are displayed, energize the high-voltage 400 VDC power bus to enable full motor movement.
