REXROTH MSK030C-0900-NN-M1-UP1-NSNN – Compact IndraDyn S Servo Motor for Precise Axes

The REXROTH MSK030C-0900-NN-M1-UP1-NSNN is a compact IndraDyn S synchronous servo motor that fits nicely where you need fast, accurate positioning on smaller axes—think pick-and-place, electronic assembly stations, indexing tables, light conveyors, or format adjustment modules. From my experience, the 030 frame typically gives you a strong torque-to-size ratio without complicating the mechanics, and the -M1 encoder version is a solid choice when you want reliable multi-turn position feedback with high resolution.

Key Features

• IndraDyn S platform – Designed for precise motion with smooth torque and low cogging; pairs cleanly with IndraDrive controllers.
• Encoder code M1 – High‑resolution multi‑turn feedback for absolute positioning over multiple revolutions; typically reduces homing time on startup.
• UP1 shaft variant – Usually indicates a keyed shaft with a radial shaft seal, helpful when you want positive mechanical coupling and IP-rated sealing.
• Winding “0900” – A factory winding option suited to applications that favor higher base speeds; in many cases it helps keep the drive in a comfortable current range.
• Compact 030C size – Easier to integrate into small cabinets and machine frames while still delivering responsive dynamics for light-to-medium load axes.
• Industrial protection – Housing and shaft sealing configurations are typically IP65 when installed with proper mating connectors.
• Thermal monitoring – Integrated temperature sensing for drive-side protection during continuous duty or high ambient conditions.

Technical Specifications

Where it fits best

You might notice that MSK030C‑0900 works especially well on compact, fast axes: carton ejectors, film feeders, lightweight Z‑axes, or small rotary knives. One thing I appreciate is how the multi‑turn feedback cuts out the homing routine on machines that are stop-start all day—it saves minutes that add up over shifts.

Related or Supporting Products

• REXROTH MSK030C-0900-NN-S1-UP1-NSNN – Similar motor with single‑turn high‑resolution feedback (S1) when absolute range over multiple turns isn’t required.
• REXROTH MSK030B series – Slightly different motor length for applications that favor a shorter stack with different torque constants.
• REXROTH MSK040 series – Next frame size up for higher continuous torque while keeping the same IndraDyn S ecosystem.
• Rexroth IndraDrive HCS01/HCS02 – Matching servo drives; pick current rating and interface to match your controller and required dynamics.
• Rexroth power and feedback cables for MSK – Shielded cable sets with IP‑rated connectors; choose lengths and straight/angled plugs to suit your cabinet layout.

If you’re replacing an existing axis, send the full nameplate and drive type. In many cases we can suggest a drop‑in MSK030 variant or a gearing tweak to keep your inertia ratio in the sweet spot.

Installation & Maintenance

• Mounting – Use the front flange with clean, flat mating surfaces. Align couplings to avoid shaft side‑load; the UP1 keyed shaft helps with positive engagement.
• Cabinet & Ventilation – Maintain free airflow around the motor body; avoid enclosing the housing unless you provide derating. Keep feedback and power cables separated from high‑noise conductors.
• Wiring – Use the correct Rexroth power/feedback connectors. Proper shielding and grounding to the drive usually reduces EMI and improves encoder reliability.
• Safety – Lock out power, discharge the drive DC bus, and verify PE continuity before mechanical work. Observe torque limits on shaft keys and coupling screws.
• Routine care – Periodically inspect connectors and seals for ingress, check bearing noise during scheduled downtime, and review drive logs. Firmware updates on the drive can improve encoder handling and diagnostics.
