• DC Servo Motor Systems: Paired with FANUC 10M/20M/30M DC servo motors.

• Retrofit Projects: Replacement or upgrade of aging DC servo systems in older machinery.

Installation Instructions

• Mount the drive vertically on a rigid, flat metal panel to ensure proper cooling and minimize vibration.

• Maintain 100mm clearance around all sides for airflow and wiring access.

• Ensure the mounting surface is clean, flat, and free of conductive debris to prevent short circuits.

• Secure the drive with four mounting bolts (M5/M6) tightened to 2.5–3.0N·m torque.

• Avoid installation in direct sunlight, near heat sources, or in corrosive/explosive atmospheres.

Wiring Requirements

• Power Wiring:

  • Disconnect all AC power before wiring to prevent electric shock.

  • Connect three‑phase AC 185V to terminals L1/L2/L3; ensure correct phase sequence.

  • Connect protective earth (PE) to the chassis ground terminal (ground resistance ≤4Ω).

• Motor Wiring:

  • Connect DC servo motor armature to terminals M+/M−; match motor polarity.

  • Connect tachometer feedback wires to dedicated terminals (TACH+/TACH−).

• Control Wiring:

  • Run analog command cable (0–10V) from CNC controller to drive’s velocity command terminals.

  • Separate control cables from power cables by ≥15cm to reduce electromagnetic interference.

  • Use shielded cables for encoder/feedback signals; ground shields at both ends.

Operation Guidelines

• Power‑On Sequence:

  1. Turn on CNC controller first; verify no alarms.

  2. Enable servo power; check that BRK and HVAL LEDs are off.

  3. Run no‑load test: check for abnormal noise, vibration, or overheating.

• Operating Limits:

  • Do not exceed rated voltage, current, or continuous torque.

  • Avoid frequent start/stop cycles (>10 cycles/min) to prevent overheating.

  • Monitor drive temperature; keep case temperature <60°C during operation.

• Alarm Handling:

  • BRK (Red): Overcurrent or short circuit → Check motor wiring, load, or drive IGBTs.

  • HVAL (Red): Overvoltage → Check input AC voltage or regenerative circuit.

  • EXCESS ERROR: Position following error → Check encoder, wiring, or mechanical load.

Maintenance Instructions

• Monthly:

  • Disconnect power; clean dust/debris from drive vents and heat sinks with dry compressed air.

  • Check all wiring terminals for tightness; re‑torque loose screws.

• Quarterly:

  • Inspect power cables, motor cables, and encoder cables for wear, cracking, or damage.

  • Verify operation of alarm LEDs and circuit breakers via test cycles.

• Annually:

  • Check internal electrolytic capacitors for bulging or leakage (replace if degraded).

  • Test tachometer and encoder signal quality with a multimeter/oscilloscope.

• Prohibitions:

  • Do not open the drive chassis or modify internal components (voids warranty).

  • Do not operate the drive with missing or damaged covers.

Safety Precautions

• Only qualified electrical technicians may install, wire, or maintain the drive.

• Disconnect all power and wait 5 minutes for internal capacitors to discharge before maintenance.

• Never touch live terminals or internal components when power is applied.

• Ensure reliable grounding to prevent electric shock and reduce noise interference.

• Keep the drive and cables away from flammable materials and high‑temperature surfaces.

• Do not use the drive if it shows physical damage, water ingress, or abnormal noise.
