• Verification note: Third-party technical records for the exact 8LSA75.E1022D200-0 report 2,000 rpm, 7.5 Nm, 22.5 Nm peak torque, EnDat 2.2 multi-turn feedback, IP65, and a 22 mm × 50 mm keyed shaft. These figures should be checked against the physical nameplate before drive commissioning.

There is conflicting online information for this part number. Another listing claims 22 kW, 70 Nm, and 2,000 rpm, while a separate B&R-related application document identifies 8LSA75.E1022D200-0 as a B&R motor used on a WEISS indexing table. Those inconsistencies are substantial enough that I would not use reseller electrical data for drive sizing without OEM verification.

B&R’s 8LS family contains numerous 8LSA75 variants, including 8LSA75.D1022D200-0, 8LSA75.D1030D200-3, and 8LSA75.EA030D600-3. Matching only the 8LSA75 frame is therefore insufficient for a replacement.

 

Product Introduction

The B&R 8LSA75.E1022D200-0 is a large-frame 8LS synchronous servo motor intended for closed-loop industrial motion applications. Available technical records identify the E1022 configuration as a 2,000 rpm motor with approximately 7.5 Nm rated torque and EnDat 2.2 absolute multi-turn feedback. It is associated with B&R ACOPOS motion-control systems.

The important procurement issue is configuration matching. The 8LSA75 family contains different windings, feedback systems, shaft arrangements, and speed ratings. Do not substitute another 8LSA75 without checking the complete material number, encoder, mechanical interface, brake arrangement, and drive parameters.

Installation & Configuration Guide

Stage 1: Pre-Installation Preparation — Approximately 10 Minutes

⚠️ Safety First: Notify operations, place the machine in a verified safe state, isolate the servo drive, and apply lockout/tagout. Do not rely on a fixed waiting period to establish DC-bus discharge. Follow the installed B&R drive procedure and verify the electrical state before touching the motor circuit.

Tools Required:

• ESD wrist strap
• Multimeter
• Torque wrench
• Hex/socket tools
• Wire labels
• Smartphone for reference photographs
• Mechanical alignment equipment

Data Backup:

1. Save the current B&R Automation Studio project.
2. Record the complete motor material number.
3. Photograph the motor nameplate.
4. Record the installed servo drive model.
5. Photograph the motor connector and cable routing.
6. Record current motor and axis parameters.
7. Photograph the coupling and mounting arrangement.
8. Save current drive diagnostics before removing the motor.

⚠️ For this model, do not rely on a generic 8LSA75 parameter set. The exact E1022D200 configuration must be matched.

Stage 2: Removing the Old Motor — Approximately 10 Minutes

1. Verify zero hazardous energy.
2. Remove the necessary machine guards.
3. Label the motor cable and feedback connection.
4. Photograph connector orientation.
5. Disconnect the motor connection without forcing the connector.
6. Release the coupling, gearbox, indexing table, or driven mechanism.
7. Support the motor before removing mounting hardware.
8. Remove the mounting bolts.
9. Withdraw the motor straight from the mounting face.
10. Inspect the shaft, flange, centering register, coupling, and connector.

⚠️ Do not use the mounting bolts to force a misaligned coupling apart. That is an easy way to turn a routine motor replacement into a bearing or coupling problem.

Keep the original motor until the replacement has completed commissioning.

Stage 3: Installing the New Motor — Approximately 10 Minutes

1. Verify 8LSA75.E1022D200-0 on the nameplate.
2. Confirm the feedback configuration.
3. Verify the shaft geometry against the existing coupling.
4. Check the mounting flange and centering dimensions.
5. Inspect the coupling for wear.
6. Clean the mounting surfaces.
7. Align the motor with the driven equipment.
8. Do not pull a misaligned shaft into position using the mounting bolts.
9. Install and torque the mounting hardware according to the machine/OEM specification.
10. Connect the motor/feedback cable.
11. Confirm connector clearance throughout the machine’s travel.
12. Secure the cable against vibration and mechanical strain.

Self-Checklist:

• Complete material number verified
• E1022 configuration verified
• EnDat feedback verified
• Shaft configuration verified
• Brake configuration verified
• Coupling aligned
• Mounting hardware torqued
• Connector seated
• Cable routing checked

Stage 4: Power-On & Testing — Approximately 15–20 Minutes

1. Inspect all motor and feedback connections before energizing.
2. Verify there are no wiring shorts.
3. Energize the control system according to the machine procedure.
4. Check the B&R drive diagnostic state.
5. Open the applicable Automation Studio project.
6. Confirm the configured motor corresponds to the replacement.
7. Verify the feedback configuration corresponds to the EnDat encoder.
8. Check the motor’s configured speed and torque values against verified OEM data.
9. Perform a low-speed jog.
10. Verify rotation direction.
11. Verify absolute position feedback.
12. Check following error.
13. Monitor motor current and drive temperature.
14. Run the axis through its intended operating range.
15. Execute the complete machine motion sequence before production release.

⚠️ Stop commissioning if the drive reports an encoder identification or motor-data mismatch. Do not compensate by manually entering approximate parameters.

Technical Pitfall & Survival Guide

1. ❗ Conflicting Electrical Specifications

This exact part number is associated with substantially different electrical figures in different online databases.

Avoidance: Use the physical nameplate and applicable B&R documentation as the commissioning authority. Do not use a reseller’s generic 8LSA75 data to size the drive.

2. ❗ E1022 Configuration

E1022 is part of the motor’s configuration identity. It should not be treated as an interchangeable frame designation.

Avoidance: Match the entire material number rather than purchasing an unspecified “8LSA75.”

3. ❗ Encoder Mismatch

Available data identifies this configuration with EnDat 2.2 absolute multi-turn feedback. B&R’s 8LS family also contains resolver and other encoder variants.

Avoidance: Verify the encoder type before connecting the motor to the drive.

4. ❗ Mechanical Interface

One technical listing identifies a 22 mm × 50 mm keyed shaft. Another 8LSA75 configuration may have different mechanical details.

Avoidance: Measure or photograph the original shaft and compare it with the exact replacement drawing.

5. ❗ Brake Configuration

Do not assume that every D200 motor has the same brake rating. Verify the actual brake specification for the -0 revision.

For vertical axes, this check is mandatory.

6. ❗ Application-Specific Matching

The 8LSA75.-0 appears in documentation for a WEISS rotary indexing application, demonstrating that this motor can be part of a specific OEM machine combination rather than a generic drop-in motor.

Keep the original motor documentation and machine configuration until the replacement has passed the complete motion test.

 

Frequently Asked Questions (FAQ)

Can the B& be hot-swapped?

No. Isolate the servo drive and machine energy before disconnecting the motor. Follow the installed B&R drive’s DC-bus discharge procedure and verify the electrical state before working on the motor circuit.

What are the rated speed and torque?

Available technical records identify this exact model at approximately 2,000 rpm rated speed and 7.5 Nm rated torque, with approximately 22.5 Nm peak torque. Because other online sources report conflicting values, these figures should be confirmed against the physical motor nameplate before commissioning.

What encoder does this motor use?

Available listings identify an EnDat 2.2 absolute multi-turn encoder.

Do not assume that another 8LSA75 with a similar suffix uses the same feedback technology. B&R’s 8LS family includes both EnDat and resolver configurations.

Is this a direct replacement for another 8LSA75 motor?

Not automatically. The complete part number matters. Compare winding/rated point, encoder, shaft, connector, brake, speed, torque, and mounting dimensions before approving a substitution.

Will replacing the motor erase the PLC program?

Normally, no. Physical motor replacement does not erase the PLC application. However, the servo axis configuration and drive parameters must be preserved and checked.

Save the Automation Studio project before removal and record the existing motor identification and drive configuration.

Does this motor have a brake?

Do not assume the brake specification from another 8LSA75 variant. The D200 designation identifies a particular configuration, but the exact brake torque for should be confirmed from the physical nameplate or OEM documentation before using it on a vertical axis.

Why are different websites showing different specifications?

Because B&R has many closely related 8LSA75 configurations, and third-party databases sometimes combine data from different variants. For this exact part number, published values range from approximately 7.5 Nm / 2,000 rpm to much larger figures.

For procurement and drive sizing, the complete B&R material number plus physical nameplate should take precedence over a reseller database.

What condition should I specify when purchasing?

State the condition explicitly:

• Factory Sealed
• New Original / New Surplus
• Refurbished (tested)

For refurbished stock, request the serial number, nameplate photograph, encoder test, insulation-resistance test, brake test where applicable, and functional test report. A generic “tested” claim is not equivalent to factory-new condition.
