Rexroth MSK071C-0200-NN-S1-UG0-NNNN Servo Motor S1 Singleturn 12Nm

This MSK071C uses S1 singleturn feedback rather than an M1 multiturn encoder. It is relevant to an existing positioning axis whose control program and reference sequence are designed for that feedback arrangement. The 0200 winding, plain shaft and absence of a holding brake remain essential to identifying the correct spare.

Application and Selection

Consider this configuration for positioning axes with a homing strategy where the machine specification already calls for MSK071C-0200. For a new axis or a changed load, compare the required speed-torque envelope, acceleration cycle, cooling conditions and mechanical drawing before selection. The motor frame alone does not establish suitability.

The machine homing strategy must be checked when replacing an encoder variant. Singleturn feedback does not provide the same multi-revolution absolute position information as M1.

Key Features

• 12 Nm continuous standstill torque at 60 K, with a separate 44 Nm maximum torque limit.
• Optical singleturn Hiperface, 128 signal periods; the feedback variant is part of the complete order code.
• Plain shaft with shaft sealing ring; rotatable plug, 240 degrees.
• Brake-free configuration for installations that do not require an integral holding brake.

Supply and Inquiry Information

Request a quotation for MSK071C-0200-NN-S1-UG0-NNNN, material number R911317802. Send the required quantity, delivery country and postal code, preferred condition, and requested arrival date. For a breakdown replacement, attach readable photographs of the original nameplate, shaft and connectors, together with the machine and drive identification.

Ask the offer to confirm the 0200 winding, S1 feedback and UG0 configuration explicitly. The quotation should identify the actual offered unit, condition, price, delivery estimate and included items. Availability and commercial terms require confirmation for the specific request; the product description is not a stock reservation.

If cables, a coupling, a shaft key or inspection records are needed, list them separately in the RFQ. Request nameplate and condition photographs before order approval, and agree any functional-test evidence, packing requirements and warranty terms in writing.

Compatibility and Replacement Note

Match the complete motor code and material number first. Then check the mechanical interface, drive feedback support, winding data, brake circuit where fitted, cables and machine parameter set. An HCS or HMS designation alone does not establish compatibility. Any proposed alternative needs separate engineering approval and commissioning checks.

Buying and Replacement FAQ

Q1. What should I send to obtain a quote for MSK071C-0200?

Use the full code MSK071C-0200-NN-S1-UG0-NNNN and reference R911317802. Include quantity, destination and required date. A clear nameplate photograph helps prevent a different encoder, winding or shaft option from being quoted.

Q2. Is an M1 motor a plug-in upgrade from this S1 version?

Do not assume so. S1 and M1 provide different position information. The drive settings, feedback support and machine reference sequence must be reviewed before changing the encoder variant.

Q3. What evidence should I request for the UG0 configuration?

Ask for readable nameplate and connector photographs plus a shaft-end image. Confirm the plain shaft with shaft sealing ring and rotatable plug, 240 degrees. Confirm that the offered unit is the brake-free version; do not approve a brake-equipped substitute without checking the revised assembly.

Q4. Can my existing servo drive operate this replacement?

Provide the complete drive and control-section codes, firmware information and original motor details. The review must cover the 0200 winding and S1 feedback as well as cables and machine parameters. Do not approve a motor solely because both products belong to the same drive family.

Q5. Are connection cables and mechanical accessories included?

The model identifies the motor configuration, not a complete installation kit. Ask the quotation to list the motor, cables, coupling and any separate shaft key individually. For the plain shaft, check the existing coupling bore and clamping arrangement rather than assuming a coupling will be supplied.

Q6. How are availability, condition and delivery confirmed?

Request a written offer against R911317802 stating the full model, offered condition, quantity, delivery estimate and validity. Agree required photos or test evidence before payment. If the exact item is unavailable, require any alternative to be identified separately and reviewed before acceptance.
