Functional Role & Application Analysis
The ACC-24E2-2CH acts as a dedicated 2-axis expansion board for Delta Tau UMAC and MACRO Station controllers. It provides digital PWM outputs for direct commutation of servo amplifiers. This module solves the integration challenge of adding high-speed, direct-drive axis control to existing 3U rack systems without replacing the main CPU. It is specifically designed for applications requiring tight current-loop control and direct amplifier interfacing.
- Use Case 1: Expanding axis count on legacy UMAC controllers for multi-axis CNC machines.
- Use Case 2: Direct PWM interfacing with custom or OEM servo amplifiers in robotics and automation.
- Use Case 3: Critical maintenance and direct replacement for failed ACC-24E2 series boards in aging manufacturing equipment.
Our Quality Standard & Testing Process
We understand that the cost of an unreliable part is far greater than its purchase price. A failed servo interface board can cause motor runaway or system crashes. We have established a rigorous, multi-stage testing process to ensure every ACC-24E2-2CH module we ship is 100% functional and ready for immediate deployment.
- Visual & Component Inspection: All parts undergo professional cleaning and visual inspection under magnification. We check for physical damage, corrosion, and compromised solder joints.
- Live System Test: The module is installed in a live Delta Tau UMAC test rack and run for 24 hours to verify continuous operation, thermal stability, and backplane communication.
- Full-Function Diagnostics: We simulate encoder feedback and test PWM output waveforms to verify the full range and accuracy of both servo channels.
- Warranty Backing: Only parts that pass all diagnostic tests are approved for shipment and backed by our full 12-month warranty.

Compatibility & Migration Paths
To ensure this ACC-24E2-2CH is 100% compatible with your system, you must check these key compatibility points. Failure to verify this is a common project risk that leads to costly downtime during installation.
- Firmware/Hardware Revisions: You must confirm your existing UMAC or MACRO CPU firmware supports the ACC-24E2-2CH hardware revision. Check the DIP switch settings (S1) for proper backplane addressing.
- Required Components: This module requires a compatible 3U backplane and proper ±15V power supply. Verify your power budget if stacking multiple expansion boards.
- Replacement & Alternatives: The -2CH is a 2-channel PWM variant. If you require analog ±10V outputs, consider the ACC-24E2A. For pulse/direction outputs, the ACC-24E2S may be applicable.
