- Connector: M23 19-pin (main) + M12 8-pin (encoder)
- Heat Sink: Extruded Aluminum 6063-T5
Working Principle:
The AKD drive receives a motion command (position, velocity, or torque) via EtherCAT or analog input. The internal DSP (Digital Signal Processor) executes a cascaded control loop: outer position loop → velocity loop → inner current loop. The current loop uses space-vector PWM (SVPWM) to generate three-phase sinusoidal voltages that drive the servo motor. The feedback encoder provides real-time position/velocity data that closes the loop, achieving sub-millisecond response times.
Advantages:
- Fully automated commissioning via Auto-Tune eliminates manual parameter entry
- EtherCAT native integration enables synchronization to < 1 µs jitter in multi-axis systems
- Compact footprint (74 x 115 x 136 mm) saves panel space
- Safety-integrated (STO) reduces need for external safety relays
- Wide feedback compatibility supports Hiperface, EnDat, BiSS, SSI, and incremental encoders
Applicable Industries:
- Semiconductor Wafer Handling
- Medical Device Manufacturing
- Lab Automation
- Printed Circuit Board (PCB) Assembly
- Precision Cutting and Welding
Installation Requirements:
- Mount vertically on a DIN rail (35 mm) or screw-mount to panel
- Ensure minimum 50 mm clearance on top and bottom for convection cooling
- Connect DC bus with 10 mm² minimum cable cross-section
- Ground chassis to protective earth (PE) with < 0.1 Ω resistance
- Use shielded cable for all encoder connections; ground shield at drive end only
Usage Notes:
- Do not operate without a connected motor or dummy load (drive will fault)
- Verify DC bus polarity before powering on; reverse polarity destroys the drive
- Update firmware via Kollmorgen Workbench before first commissioning
- Do not exceed ambient temperature of 50°C; derate current by 2% per °C above 40°C
