Lenze MAS07C30MB0 Servo Motor — MCS / MAS 3.0 Nm Medium-Inertia Synchronous Servo, Resolver Feedback

Lenze · MAS / MCS Series · 3.0 Nm Rated Torque · 4500 rpm · Resolver · IP65

The MAS07C30MB0 is a synchronous AC servo motor from the Lenze MAS small-servo family, sized at 3.0 Nm continuous stall torque with a 70–80 mm flange, medium rotor inertia, and a resolver feedback element in the B0 (smooth-shaft) configuration. It is the drop-in axis of choice on packaging, material handling and machine tool cells that pair with the Lenze i510, i550, i700 or i950 servo drives. If your line mixes Allen-Bradley Kinetix, Siemens SINAMICS, Mitsubishi MR-J4, Omron 1S, Fanuc βi, Schneider Lexium, Yaskawa Σ-7, Panasonic MINAS A5/A6 and KEYENCE axes, KOEED can quote the MAS07C30MB0 and its matching Lenze drive in the same BOM, dispatched from a single multi-brand source.

1. Key Technical Specifications & Overview

The MAS07C30MB0 is the small-flange end of the Lenze MAS / MCS synchronous-servo family. The model code reads in plain English: MAS = small synchronous servo, 07 = 70–80 mm flange, C30 = 3.0 Nm continuous rated torque, M = medium rotor inertia, B0 = resolver feedback (B) / smooth shaft (0). It is normally deployed where the original axis was a Lenze MCS or earlier MDF/MDG servo and the spare needs to be a true like-for-like replacement, or where the cabinet already runs a Lenze i-series drive on i500 / i510 / i550 firmware. The card below is the spec KOEED quotes against; the full datasheet is released on request when you send your BOM to Moritta@KOEED.COM.

2. Application Scenarios — Where the MAS07C30MB0 Fits

The MAS07C30MB0 is sized for the small-flange end of a typical factory automation line. The medium-inertia rotor makes it a good match for loads that swing — indexing tables, belt-pulled conveyors, winders and small hoists — rather than the very-low-inertia pick-and-place work handled by Yaskawa Σ-7 or Panasonic MINAS A5 in the same torque class. In practice we see it land in the following contexts:

• Packaging lines — horizontal-form-fill-seal (HFFS) axes, vertical baggers, label applicators, and small track reject arms on lines originally built around a Lenze controller-front-end.
• Material handling and intralogistics — belt conveyors, roller drives, pallet shuttle axes, and small AGV drive wheels where 3.0 Nm at 4500 rpm covers the duty cycle without oversizing.
• Winding and dosing — film / foil winders, label-stock rewind stations, pump and volumetric dosing axes that need smooth torque across a wide speed range.
• Machine tool auxiliary axes — tool magazines, ATC arms, chip-conveyor drives, and small rotary tables running alongside a Fanuc / Mitsubishi CNC front-end.
• Vision inspection conveyor and diverter axes — short-stroke slides downstream of KEYENCE or Siemens vision stations.
• End-of-line palletizing and case-packing cells — small layer-forming axes, gantry lifts, and case-rotary stations with a Schneider Modicon M340/M580 or Allen-Bradley CompactLogix / ControlLogix supervisory PLC.
• Laboratory automation and OEM instrument build-out — pipette heads, plate handlers, analyzer turrets, and small Omron-controlled indexing cells where the original Lenze motor needs a like-for-like spare.

If your line mixes Lenze MAS / MCS axes with motors from Allen-Bradley Kinetix, Siemens SIMOTICS, Mitsubishi or Yaskawa in the same machine, KOEED can quote the full axis set in one BOM — motor, drive, cable, and connector — so the same shipping window covers all brands.

3. Integration & Wiring Notes

Wiring the MAS07C30MB0 into an existing Lenze cabinet is straightforward if the original drive firmware is intact, but four details cause most field-return tickets we see, so they are worth a careful pass before power-on:

• Drive pairing. Pair the MAS07C30MB0 with a Lenze i510 (low-end), i550 (mid-range), i700 (high-end), or i950 (cabinet-free) servo drive. Resolver feedback needs the matching resolver option card in the drive. A drive that was set up for Hiperface or EnDat will not see a resolver motor — check the drive parameter FBTYPE before commissioning.
• Encoder / resolver cable shielding. Use the Lenze-recommended shielded resolver cable, terminated with the proper M23 connector at the motor end. Do NOT route the resolver cable in the same conduit as the motor power leads; this is the most common source of intermittent position errors on MAS / MCS axes.
• Power lead phasing (U / V / W). Phase rotation determines motor direction. If the swap-in motor runs in the wrong direction, swap any two of U, V, W — do not re-tune the controller to invert the command direction in the application program.
• Holding-brake variant. If the original MAS axis had an electromagnetic holding brake, confirm the variant in your BOM has the brake option. The unbraked and braked versions of the MAS07 share a frame but differ in connector pin-out, cable exit, and overall length. KOEED can quote both versions in the same RFQ.
• Grounding and PE. Bond the motor body to the cabinet PE bus with a short, dedicated pigtail. The resolver cable shield should land at the drive end only, not at the motor end, to avoid ground-loop noise coupling into the resolver signal.
• Parameter restore. In the Lenze EASY Starter tool, restore the axis parameters from the project backup or load the Lenze motor database file (.mls) shipped with the new motor. The motor nameplate data (rated current, torque, pole count, resolver pole pairs) must match the loaded parameter set.

If you are also replacing the matching drive or migrating an older Lenze MCS axis to the current MAS platform, send the whole axis (motor + drive + resolver cable + power cable) to KOEED as one BOM line so we can pre-confirm connector pin-out, cable length, and drive firmware level before shipping. See the full servo motor and servo drive catalog for upstream and downstream parts.

4. Installation & Commissioning Tips

A MAS07C30MB0 swap takes 30–60 minutes if you follow the same commissioning recipe Lenze recommends in the EASY Starter wizard. These are the steps our technical desk walks through on a typical MAS / MCS replacement:

1. Mechanical mount. Bolt the replacement to the existing flange using the same M-size fasteners. The 70–80 mm flange is a true like-for-like match for the previous MAS / MCS axis; confirm pilot diameter and bolt-circle before tightening the fasteners to the OEM torque spec.
2. Connector inspection. Inspect the power and resolver connectors for bent pins, oxidation, or residual paste from the failed motor. Replace the connector if any pin shows damage — it is cheaper than a second motor.
3. Parameter load. In Lenze EASY Starter, connect to the drive via USB or Ethernet, then load the .mls motor database file for MAS07C30MB0. Verify the resolver pole pair count (1) and rated current (per nameplate) are written into the drive.
4. No-load jog test. Run a slow jog in both directions at 50–100 rpm and listen for bearing noise, watch for vibration, and verify the resolver counts match the commanded distance. The medium-inertia rotor should spin up and brake smoothly without cogging.
5. Auto-tune with load. Run the Lenze auto-tune routine with the load attached (conveyor, winder, indexing table). Avoid using a previously saved gain set from a different motor — each unit, even of the same P/N, has its own resonance.
6. Run a full cycle. Take the axis through one full machine cycle and monitor drive temperature, motor current, and resolver position error under steady-state load before handing the line back to production.

If you are migrating from an older Allen-Bradley 1326 or Siemens 1FK7 motor to the MAS07C30MB0, the mechanical envelope is similar in the 3 Nm class, but the resolver feedback and Lenze drive firmware require a controller-side mapping change in addition to the mechanical swap. Budget a half-day for engineering bench time and confirm the drive has the resolver option card before the install window.

5. Procurement, Warranty & Lead Time

The MAS07C30MB0 is stocked as a single-piece aftermarket spare (not a multi-pack). KOEED sources the motor through its China sourcing network, and each unit is bench-checked for resolver sine / cosine amplitude, insulation resistance, and bearing smoothness before dispatch. Typical procurement flow:

• RFQ turnaround. Quote within 24 hours on business days — send your part list, the OEM P/N of the failed motor, and a one-line note on the machine to Moritta@KOEED.COM.
• Lead time. Single-piece aftermarket stock typically ships within 3–5 business days from Hong Kong or Shenzhen. Worldwide shipping via DHL / FedEx / UPS is available to North America, Europe, the Middle East, Southeast Asia and South America.
• Warranty. 90-day limited warranty on aftermarket units, covering resolver failure, winding open / short, and bearing seizure under rated load. The warranty does not cover mechanical damage from incorrect mounting, contamination, or operation outside the rated envelope (torque, speed, IP rating).
• Documentation. Each unit ships with a bench-test sheet (resolver sine / cosine amplitude, insulation resistance, no-load current). Full Lenze datasheet and CE / RoHS paperwork available on request.
• Multi-axis and mixed-brand BOMs. If the line also needs a matching Lenze i550 drive, resolver / power cables, or Allen-Bradley / Mitsubishi / Siemens spares for the same repair window, send them together so we can ship the whole kit in one parcel.
