Kollmorgen BJRL-20012-110001 Servo Drive

Description

Product Introduction & Engineering Value

Replacing an older servo amplifier is rarely just a matter of matching voltage and mounting dimensions. The BJRL-20012-110001 belongs to a legacy Kollmorgen drive family, so the motor, feedback arrangement, control interface, and drive configuration all need to be considered together. Available technical references describe a 35–130 VAC, 50/60 Hz input range and a 4-quadrant V-MOS output stage.

This type of drive is valuable primarily when an installed machine still depends on its original Goldline architecture. Keeping a verified spare available can avoid an unnecessary controls redesign when the existing machine remains mechanically and electrically serviceable.

Technical Specifications

The 6.5 A continuous-current and 30 kHz switching-frequency figures come from a secondary technical reference and should be treated as identification-level information rather than a substitute for the original Kollmorgen rating documentation. The 35–130 VAC input range and Goldline classification are corroborated by multiple sources.

Field Application & the “Trench” Experience

A machine builder operating an older high-speed positioning machine encountered an amplifier failure after years of service. The replacement team initially considered migrating the axis to a current-generation servo package. That would have required changes to the motor interface, feedback wiring, cabinet layout, and machine-control software.

The maintenance group instead located a matching BJRL-20012-110001, verified the drive identification against the failed unit, inspected the motor and feedback circuits, and restored the original drive configuration. The machine returned to service without changing the higher-level motion-control architecture.

That is where this drive still makes practical sense.

Specific applications include:

• High-speed indexing axes on legacy packaging machinery
• Precision positioning mechanisms using Kollmorgen brushless motors
• Machine-tool auxiliary servo axes
• Older automated assembly equipment with rack-mounted Goldline drives
• Retrofit installations where maintaining the original servo architecture is preferable to a complete controls migration

Transparency SOP: QA & Testing

For New Surplus or Refurbished BJRL-20012-110001 inventory, a useful acceptance process should cover:

1. Identity check
Verify the complete part number, nameplate, revision information, connectors, and physical configuration.

2. Power-stage inspection
Inspect the V-MOS output section, capacitors, terminals, PCB assemblies, and heat-dissipation components for evidence of overheating or previous electrical stress.

3. Control-interface inspection
Check connectors, adjustment components, switches, and accessible control circuitry for damage or contamination.

4. Functional testing
Where the appropriate Kollmorgen motor, feedback hardware, power source, and test fixture are available, verify enable operation, motor response, feedback behavior, and fault handling.

5. Final QA record
Record the tested serial number and condition. For refurbished units, the test scope should be documented rather than simply described as “tested.”

The Veteran’s Tech Trap Guide

⚠️ Do not treat 35–130 VAC as a generic servo-drive input range.
The drive’s actual power configuration must be checked against the original machine. Secondary documentation describes both three-phase and certain single-phase supply arrangements, but that does not mean every installation can be wired either way without regard to the system design.

⚠️ The motor is part of the replacement equation.
A replacement BJRL drive should be evaluated together with the installed Kollmorgen motor, feedback device, resolver/encoder wiring where applicable, and machine controller. Do not substitute based solely on the model prefix.

PRO TIP: Before removing the failed drive, photograph every connector and record all accessible adjustment settings. Legacy servo equipment often has configuration information that is not recoverable from the machine PLC program.

⚠️ Watch for misleading catalog descriptions.
One online listing incorrectly categorizes this exact part number alongside unrelated descriptions, while several other sources identify it as a Kollmorgen servo drive. For procurement, the physical nameplate and original Kollmorgen documentation should take precedence over generic marketplace text.

Dynamic FAQ

Q1. What is the Kollmorgen BJRL-20012-110001?

It is a legacy Kollmorgen digital AC servo drive/servo amplifier associated with the Goldline Smart Drives BJR/BJRL family.

Q2. What input voltage does the BJRL-20012-110001 use?

Available references specify an input range of approximately 35–130 VAC at 50/60 Hz.

Q3. Is BJRL-20012-110001 a servo motor?

No. It is the servo drive/amplifier. It provides the electrical power and closed-loop control required by a compatible servo motor.

Q4. Can I replace BJRL-20012-110001 with a modern Kollmorgen drive?

Possibly, but not as a direct assumption. A modern replacement may require changes to the motor feedback interface, control wiring, parameterization, cabinet installation, and machine-control software. For an operating legacy machine, a verified like-for-like spare is often the lower-risk maintenance option.

Q5. What should I verify before purchasing a replacement?

At minimum, compare the complete part number, nameplate, revision, motor model, feedback arrangement, power supply, connector configuration, and original machine application. This is particularly important for older Goldline equipment.

Q6. How should New Surplus authenticity be checked?

A New Surplus unit should show original OEM identification and evidence consistent with unused inventory. Serial/nameplate information should be recorded, and the unit should not be represented as New Surplus merely because it has been cleaned or repackaged.

Warranty: Warranty terms depend on the supplier and inventory condition. For refurbished BJRL units, request the actual functional test scope and written warranty period before purchase.
