Working Principle

External regulated 24–80VDC isolated DC power supply feeds drive DC bus circuit to supply three-phase MOSFET power inverter stage. High-speed DSP motion controller processes CANopen real-time motion commands or analog ±10V torque/velocity setpoints, sampling SFD single-cable encoder rotor position feedback at 20kHz PWM cycle. Triple closed-loop PI-PDFF control algorithms dynamically adjust sinusoidal three-phase output current to eliminate linear and rotary positioning tracking deviation. During load deceleration regenerative energy is dissipated by internal dynamic braking resistor to stabilize DC bus voltage. Continuous multi-channel fault monitoring circuit samples all electrical and thermal operating parameters, executing instant power stage hardware cut-off upon fault threshold violation to protect drive and matched low-voltage AKM servo motor hardware.

Operation & Maintenance Precautions

  1. Cabinet ambient operating temperature range strictly limited to 0°C ~ +40°C; temperature above 40°C requires linear 15% continuous output current derate per 10°C temperature rise
  2. Monthly maintenance: Use clean compressed dry air to blow dust accumulated on external aluminum cooling fins
  3. Disconnect all external DC power supply and wait minimum 3 minutes for DC bus capacitor full discharge before disassembling terminal wiring
  4. Prohibit connecting servo motors with rated power exceeding 1.8 kW to avoid permanent MOSFET power stage thermal damage
  5. All SFD and CANopen cable shielding layers must implement double-end grounding to eliminate signal noise and position jitter
  6. Storage environment must maintain non-condensing relative humidity ≤85%; prohibit deployment in conductive dust or oil mist atmospheres
  7. Firmware upgrade and parameter configuration must exclusively use official Kollmorgen WorkBench software
