• TF: PTC thermistor winding temperature protection.

• RH1M: 1‑speed resolver (medium resolution), M16×1.5 connector, standard feedback.

• KK: Standard power + signal connector kit.

1.3 Safety Instructions

• Installation, commissioning, and maintenance must be performed by qualified personnel.

• Disconnect all power before mounting, wiring, or servicing.

• Contains permanent magnets; keep away from magnetic media and sensitive equipment.

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

• Protect from heavy impact, corrosive atmospheres, and excessive dust.

• IP65 protection (dust‑tight, splash‑proof).

3. Installation

3.1 Mechanical Mounting

• Mount on a flat, rigid surface; tighten all M5 flange bolts securely.

• Avoid radial/axial overload; use flexible couplings.

• Allow ≥100 mm clearance for cooling and cable bending.

3.2 Electrical Connection

• Use shielded cables for power and feedback (EMC compliance).

• TF thermistor: Connect to drive thermal monitoring (PTC, ~1 kΩ @ 25 °C).

• RH1M resolver: Connect to resolver‑compatible drive (e.g., MOVIDRIVE® MDX61B).

• Properly ground the motor housing.

4. Operation

4.1 Commissioning

• Run no‑load for 5–10 minutes; check for abnormal noise, vibration, or temperature rise.

• Verify resolver feedback and thermal protection wiring.

• Apply load gradually; monitor current and temperature.

4.2 Operating Guidelines

• Operate within rated speed/torque; avoid continuous stall.

• Max winding temperature: +155 °C (PTC trip).

• Avoid frequent heavy start‑stops.

5. Maintenance

• Lifetime grease lubrication (bearings); no regular oiling required.

• Every 6 months:

  • Check mounting bolts and cable connections.

  • Clean cooling surfaces (dry air only; no high‑pressure water).

  • Inspect shaft seal for leaks.

• Resolver is maintenance‑free.

6. Troubleshooting

• No rotation: Power loss, wiring error, or drive inhibit.

• Overtemp (TF): Overload, blocked ventilation, or PTC fault.

• Position error: Resolver wiring fault, loose coupling, or mechanical jam.

• Vibration/noise: Misalignment, loose bolts, or bearing wear.
