The DATX130 is a rotor feedback interface board used in ABB drive systems to process motor speed/position feedback signals. It is designed to receive signals from a motor's rotor position sensor (such as an encoder or resolver) and convert them into digital data for the drive's controller. This board plays a critical role in closed-loop motor control, ensuring the drive accurately maintains motor speed and torque by providing real-time rotor position feedback. The DATX130 board is typically mounted within the drive or control cabinet and features the necessary signal conditioning (e.g. wave shaping, isolation) for incremental encoder pulses or analog resolver signals. It communicates the processed feedback to the main control board (e.g. RMIO) via a backplane or ribbon cable. Built for industrial reliability, the rotor feedback board has a metal or high-grade plastic enclosure and is capable of withstanding vibrations and temperature variations common in drive applications. By using the DATX130, ABB drives achieve precise speed regulation, smooth torque control, and safe monitoring of motor shaft position as part of their overall protective functions.
| Function | Rotor position/speed feedback interface for ABB drives (processes encoder or resolver signals) |
| Sensor Compatibility | Supports common feedback devices: incremental encoders (TTL or HTL pulses), analog resolvers, or tachometer interfaces (varies by system design) |
| Signal Processing | Converts analog or pulse feedback into digital position data; includes filtering and diagnostics for sensor signals (e.g. loss of signal detection) |
| Feedback Resolution | Dependent on connected sensor (e.g. up to 1024 ppr encoder, etc.) – board preserves fine resolution for accurate speed/position loop control |
| Mounting | Pluggable board module inside drive unit (40 mm standard width, mounts via screws or card guides) – Product net weight ~0.8 kg |
| Operating Temp | 0 °C to +55 °C (ambient inside drive; extended range if in cooled enclosure) |
| Protection | Board-level surge and noise suppression on input channels; conformal coating on circuits for moisture protection (in certain models) |
| System Use | Ensures drive operates in closed-loop mode – used for speed regulation, slip compensation, and safe-stop functions (stops motor when feedback indicates incorrect conditions) |
| Safety | Facilitates Category 3/4 safe monitoring when used with appropriate drive safety module (feedback used for safe torque off in some systems) |
