Working Principle

  1. Single-phase AC mains input converted to DC power supply via analog rectifier circuit for power stage and analog control op-amp circuit
  2. External analog ±10V command signal input to velocity/torque analog PI regulator hardware circuit
  3. Resolver feedback signal converts rotor mechanical position to analog voltage feedback signal, compare with command voltage to generate analog error adjustment signal
  4. Analog error signal drives three-phase power transistor analog sine-wave modulation circuit to output adjustable amplitude alternating current to servo motor stator windings
  5. Hardware analog overcurrent, overvoltage and over-temperature protection circuit instant cuts power stage drive signal upon parameter threshold exceedance, no digital fault code storage function

Applicable Industries

Legacy analog CNC machine tool renovation projects, old printing label analog slitting equipment, vintage textile analog warp knitting machinery, small analog automated assembly equipment, laboratory analog precision positioning test platforms

Installation Requirements

  1. Vertical mounting on standard 35mm DIN rail; maintain 70mm minimum top/bottom ventilation clearance for passive heat sink convection cooling
  2. Servo motor power cable cross-section ≥1.0mm² copper wire; resolver feedback cable must use dedicated shielded twisted pair analog signal cable
  3. Unified cabinet grounding bar connection, grounding resistance ≤4Ω; signal cable shield layer single-end grounded at drive terminal side only
  4. Analog command signal wiring and motor power wiring laid in independent cable troughs, minimum 10cm separation distance to eliminate analog voltage signal interference
  5. Installation environment free of metal dust, oil mist and condensation; air filter installed at cabinet air intake for dusty workshop renovation sites

Usage Precautions

  1. Cut off main AC power supply and wait 5 minutes for DC bus capacitor discharge before adjusting front panel analog potentiometers or disassembling wiring terminals
  2. Forbid motor three-phase output terminal short-circuit under powered state; analog power transistor bridge suffers permanent breakdown damage
  3. Analog command signal wire cannot share wiring trough with high-frequency inverter power cables; coupling interference causes severe motor velocity jitter

    3. Analog command signal wire cannot share wiring trough with high-frequency inverter power cables; coupling interference causes severe motor velocity jitter
    4. Avoid continuous operation above 40°C ambient temperature; passive heat sink over-temperature triggers unadjustable hardware current limiting and torque reduction
    5. Do not install near high-vibration stamping or cutting equipment; long-term vibration loosens analog potentiometer internal sliding contacts and generates unstable velocity signals
    6. Conduct quarterly visual inspection of heat sink fins for dust accumulation; accumulated dust blocks natural airflow and accelerates component aging
    7. No digital fault storage function; all fault judgment relies on front panel indicator lamp status, record lamp state immediately after equipment fault shutdown for troubleshooting
