Product Introduction
Rexroth MSK101D-0200-NN-M1-AG0-NNNN is a synchronous servo motor designed for demanding industrial automation tasks. It provides closed-loop positioning and speed control with high dynamic response.This motor delivers 231 Nm of peak torque at speeds up to 6000 RPM. The natural convection cooling eliminates fan maintenance, while the IP65 rating protects against dust and water jets in harsh environments.
Installation & Configuration Guide
Preparation (10 min)
- Verify the drive controller is powered OFF and locked out.
- Confirm the IndraDrive controller model is compatible with MSK series.
- Gather torque wrench, cable connectors, and anti-static gear.
Removal (5–10 min)
- Disconnect power and encoder cables from the A-side connector.
- Unbolt the motor from the machine mounting flange.
- Remove the coupling or pulley from the output shaft.
- Inspect shaft and flange for wear or damage.
Installation (10 min)
- Align the motor shaft with the driven equipment.
- Secure the motor to the mounting flange using specified torque values.
- Connect the power and encoder cables to the A-side connector.
- Route cables to avoid bending radius violations (<30 cm from connector).
Power-On & Test (10 min)
- Restore power to the IndraDrive controller.
- Execute motor commissioning routine in IndraWorks.
- Verify encoder feedback matches actual position.
- Run low-speed test, then full-speed ramp test.
Troubleshooting Quick Reference
| Symptom | Probable Cause | Quick Check | Corrective Action |
|---|---|---|---|
| Motor won’t enable | Encoder fault | Check encoder cable continuity | Reseat M1 connector; replace cable |
| Overtemp warning | Cooling blocked | Inspect motor surface clearance | Ensure 20mm clearance on all sides |
| Position drift | Encoder misalignment | Verify multi-turn alignment | Re-run encoder calibration routine |
| Excessive vibration | Mechanical misalignment | Check shaft runout (DIN 42955) | Realign coupling; inspect bearings |
| Comm error | Cable damage | Inspect A-side connector pins | Replace damaged cable; verify pinout |

FAQ
Is this motor compatible with IndraDrive Cs drives?
Yes. The MSK101D-0200-NN-M1-AG0-NNNN integrates directly with IndraDrive Cs and other Rexroth servo drives.I need this motor urgently. What’s your lead time?
Tested units ship within 24–48 hours. We stock common MSK101 variants for emergency replacements.Can I use liquid cooling instead of natural convection?
No. The “NN” designation means natural convection only. Liquid cooling requires the “FN” variant with integrated coolant ports.Does this motor work in explosive atmospheres?
Yes. It carries ATEX certification for Zone 2 and Zone 22 explosive environments.What encoder resolution does the M1 option provide?
The M1 encoder is optical, multi-turn Hiperface with 128 increments per turn. Verify this matches your drive’s encoder configuration.Do I need special cables for the A-side connector?
Use Rexroth-specified IndraDrive connection cables. Generic connectors may cause signal integrity issues — don’t risk it.How do I verify the motor hasn’t been damaged in shipping?
Check the shaft runout against DIN 42955 specs and inspect the A-side connector for bent pins before installation.
