ABB KSD211B 3BHE022455R1101 Input Coupling Unit

Joint drive control for ABB industrial robots (such as the IRB series) to ensure precise motion control;

Servo drives for spindle and feed axes, supporting high-speed cutting and precision machining;

Servo motor drives for conveyor belts and robotic arms to achieve positioning and synchronous control;

Motor drives for high-speed sorting and sealing equipment to ensure operational stability.

Power Range: Suitable for motors with power approximately 0.5-3kW (specific parameters to be referenced from the motor);

Control Modes: Supports Position Mode, Velocity Mode, and Torque Mode;

Feedback Interfaces: Compatible with incremental encoders (e.g., 1024/2048 lines) and absolute encoders (SSI, BiSS-C protocols);

Communication Protocols: Integrates ABB DriveBus, EtherCAT, Modbus RTU, etc., supporting real-time communication with PLC/DCS systems;

Dynamic Performance: Current loop bandwidth ≥1kHz, speed loop response time ≤1ms, supporting high-speed start/stop and trajectory interpolation.

Power Input:

Protection Functions: Overcurrent, overvoltage, overheat, and short-circuit protection, supporting emergency stop (STO Safe Torque Off);

Wiring Method: Modular terminal blocks support separate wiring for power and signal cables to reduce interference;

Status Indication: LED groups display operating status (power, fault, communication) and fault codes (e.g., F001 overcurrent).

Operating Temperature: 0°C to +55°C (derated for use up to +60°C);

Protection Class: IP20 (suitable for installation in control cabinets);

Anti-Interference Standards: Complies with EN 61800-3 electromagnetic compatibility (EMC) requirements, resistant to vibration (10-500Hz, 10m/s2).

Scenario: Servo motor drive for the robot's forearm joint, requiring high-speed start/stop and precise positioning (repeat positioning accuracy ±0.05mm).

Solution: KSD211B communicates with the robot controller (IRC5) via DriveBus, and the encoder feedback adjusts the position in real time, supporting trajectory planning (e.g., S-curve acceleration/deceleration).

Effect: Motion smoothness ≤0.1mm fluctuation, response time ≤0.5ms, meeting the requirements of precision processes such as welding and assembly.

Scenario: Speed control for the spindle motor (2.2kW) of a machining center, requiring stepless speed regulation from 100 to 6000rpm.

Solution: The module is configured in speed mode, receives instructions from the PLC via Modbus RTU, and achieves closed-loop control through encoder feedback, supporting rigid tapping functions.

Effect: Speed fluctuation ≤0.1%, start/stop time ≤50ms, torque fluctuation ≤5% during cutting, improving the surface finish of workpieces.

F004: Overvoltage (check if the input voltage is stable and if the braking resistor is damaged);

F010: Encoder fault (investigate cable connections and encoder battery level);

Inspect the cooling fan every 12 months (rotation speed ≥2000rpm) and clean dust from the module (Pores of protective net ≤1mm).
