Operating Instructions (Summary)

Mounting

• NEMA 34 flange: 4×M5 bolts, torque to 2.5 Nm.

• Coupling coaxiality ≤ 0.08 mm; avoid radial loads.

• Power cable ≥16 AWG; encoder: shielded twisted pair, ≤10 m.

Wiring

• Power: A+ (armature +), A− (armature −), FG (ground)

• Encoder: +5V, GND, A±, B±, Z±

Commissioning

• Drive setup: DC Servo, 90 VDC, 6.5 A, 500 PPR.

• No‑load jog at 500 RPM; check rotation, noise, encoder signal.

• Gradually apply load; monitor winding temperature (<155°C).

Maintenance

• Brushes: Inspect every 2000 hours; replace if <5 mm length.

• Bearings: Regrease every 4000 hours (Mobil XHP 222).

• Insulation test: Annually, armature‑to‑ground ≥1 MΩ (500 VDC).
