Installation & Maintenance Notes
- Mount on rigid mechanical base to minimize vibration and resonance
- Ensure proper shaft alignment during coupling installation; avoid radial/axial overload on motor bearing
- Keep motor ventilation area clean; do not cover the motor housing for natural heat dissipation
- Check connector tightness and cable shielding after installation; use shielded servo cable per Rexroth specification
- Do not perform insulation resistance test on encoder circuit to avoid encoder damage
- Regular bearing grease inspection during long term operation; replace bearings at recommended service interval
- Verify encoder wiring before power-up; incorrect wiring will cause position fault or motor damage
FAQ
Q: What is the breakdown of MSK076C-0300-NN-S1-UP0-NNNW ordering code? A: MSK = IndraDyn S servo motor; 076 = frame size; C = stator length; 0300 = winding variant; NN = no brake; S1 = Hiperface single-turn encoder; UP0 = rotatable power/encoder connectors; NNNW = mechanical and special option variant.
Q: What is the difference between S1 and M1 encoder options for MSK motors? A: S1 = Hiperface single-turn encoder, no multi-turn position memory; M1 = Hiperface multi-turn encoder with battery-free multi-turn position recording, used for vertical axes or homing-free applications.
