Features:
- Resolver processing: X and Y resolver feedback supports robot-axis measurement
- Counter retention: battery backup preserves revolution-counter data when main power is removed
- Diagnostic coverage: the measurement system reports signal, communication, and configuration faults
SMU-03 belongs to the robot measurement path, where resolver feedback and stored revolution-counter data support axis position tracking.
Its fault reporting separates signal-quality problems from measurement-link communication and missing configuration data.
A controlled service record should connect the unit label, controller events, resolver cabling, battery state, and revolution-counter recovery result.
Apter Power can review SMU-03 measurement-system evidence, condition, documentation, and sourcing requirements.

- Signal channels: the board supervises X and Y resolver feedback used by the robot measurement system.
- Quality checks: offset and linearity events help separate degraded feedback from a missing board.
- Voltage limits: high- or low-signal events direct inspection toward the resolver and its cable path.
- Board discovery: a serial-board-not-found event requires configuration, node, and link checks.
- SMS traffic: communication and transmission events identify failures in the measurement-system data path.
- Configuration data: missing board data must be resolved before position feedback is trusted in production.
- Resolver boundary: inspect signal wiring and connectors before attributing offset or voltage faults to the unit.
- Communication boundary: separate measurement-link cabling from board configuration and controller faults.
- Recovery evidence: retain event codes and revolution-counter results after the measured axis is restored.
- Robot position feedback: process resolver information within the supported ABB measurement system.
- Measurement-link diagnostics: isolate board, cable, configuration, and feedback-signal faults.
- Counter-data recovery: restore and verify robot revolution counters after approved service work.
