Each controller handles demanding real-time motion control algorithms locally at the axis level rather than shifting calculations to a master PC, reducing network latency.
The dual-axis design (2M) allows two separate direct-drive motors to run off a single controller while sharing a common DC power supply bus. This significantly optimizes cabinet space, simplifies interconnect wiring, and reduces overall system complexity.

Environmental Tolerance Conditions
To maintain long-term industrial reliability, the module must operate within the following environmental limits:
Ambient Operating Temperature: $15^\circ\text{C}$ to $40^\circ\text{C}$ (Standard factory performance range; derating may apply at higher ambient profiles).
Storage Temperature Range: $-25^\circ\text{C}$ to $70^\circ\text{C}$.
Relative Humidity: 5% to 85% non-condensing.
Ingress Protection (IP) Rating: IP20 (Designed for cleanroom, machine-cabinet, or controlled sub-assembly installation environments).
Cooling Requirement: Conductive backplate cooling or forced convection mounting configurations.
Installation Method
The controller is designed to be integrated directly within electrical backplanes or multi-axis chassis racks:
Backplate Mounting: Secure the EA-P2M controller to the machine’s main backplate using standard M5 hex screws. The mounting surface must be a flat, unpainted, grounded metal plate to guarantee reliable grounding and adequate heat dissipation.
DC Power & Bus Connection: When utilizing multiple modular controllers, connect them via standard shared DC busbars to simplify cabinet power lines.
Safety Grounding: Connect the dedicated protective earth (PE) grounding terminal directly to the central electrical ground point before applying high-voltage DC power.
Thermal Clearance: Maintain a minimum of 50 mm clearance above and below the cooling vents to facilitate natural convection or forced-air cooling paths.
Operating Instructions & Commissioning
Wiring Verification: Before applying any power, verify that the 24 VDC auxiliary control power lines are connected with correct polarity, and ensure all encoder feedback cables are fully seated.
First Power-Up: Turn on the auxiliary 24 VDC supply first. This powers up the controller’s main processor, diagnostic logic, and communication interfaces without energizing the high-voltage motor output stages.
Commissioning via ComET: Connect a PC to the drive’s USB port or local Ethernet port. Open the ETEL ComET Commissioning Software to configure motor parameters, perform automatic phase identification, and initialize position feedback calibration.
Servo Tuning: Utilize the built-in Identification Tools in ComET to run mechanical system frequency response tests, locate physical resonances, and set up the speed and position loops.
Enabling High Voltage: Once parameters are written to the controller’s flash memory and no error codes are present on the diagnostic LEDs, turn on the primary 400 VDC power supply to execute high-precision movements.
