Description

🔹 Product Introduction

The B&R AUTOMATION SV2CON2/3 is a control PCB used within B&R servo amplifier and drive-system assemblies. Available technical listings identify the unit as SV2CON2/3, also referenced as SV2C0N2/3, with part number 050003169-03. It belongs to the SV2 family of components associated with B&R servo amplifiers and inverter assemblies.

The board is a system-specific control component rather than a standalone PLC module. It should therefore be installed only in compatible B&R equipment with the correct hardware revision, connector arrangement, and system configuration.

B&R repair references also place SV2CON2/3 among components used in B&R servo amplifiers and frequency/inverter drive equipment.

🛠️ Operating Procedure & How to Use

1. Confirm the Existing Drive

Identify the complete B&R servo amplifier or inverter containing the original SV2CON2/3 board.

Record:

• Drive model
• Board part number
• Hardware revision
• Connector arrangement
• Firmware information, where available
• Existing fault codes

2. Compare the Replacement

Before installation, compare the replacement PCB with the removed board.

Check:

🔍 050003169-03 part number
🔍 SV2CON2/3 designation
🔍 PCB revision
🔍 Connector locations
🔍 Mounting points
🔍 Jumper or configuration settings

3. Isolate Power

Completely isolate the servo drive from its electrical supply. Wait for the DC bus to discharge and verify the absence of hazardous voltage before opening the drive.

4. Remove the Existing PCB

Mark connectors before removal. Disconnect cables carefully and avoid pulling directly on PCB-mounted connectors.

5. Install the New Board

Fit the SV2CON2/3 into the same mechanical position. Make sure the board is correctly seated and secured.

6. Reconnect Wiring

Reconnect every cable to its original position. Incorrect connector placement can damage the PCB or the associated servo drive.

7. Inspect Before Power-Up

Check for:

• Loose connectors
• Bent pins
• Foreign objects
• Damaged PCB tracks
• Incorrect jumper settings
• Loose mounting hardware

8. Power and Commission

Restore power using the approved B&R drive commissioning procedure. Check the drive for initialization errors and communication faults before enabling the motor.

⚡ Power-On Sequence

1. 🔒 Confirm the machine is in a safe state.
2. 🔌 Confirm all PCB connectors are correctly installed.
3. 🔍 Check motor and feedback wiring.
4. 🔍 Verify the DC-bus and drive power connections.
5. ⚡ Apply the approved control power.
6. 🖥️ Allow the B&R drive electronics to initialize.
7. 🔍 Check for hardware or communication faults.
8. 💻 Verify controller-to-drive communication.
9. 🔄 Check feedback/encoder status.
10. ⚙️ Enable the drive without mechanical load where appropriate.
11. 🧪 Perform a controlled low-speed test.
12. ✅ Return the machine to normal operation after successful testing.

🔌 Power-Off Sequence

1. 🛑 Stop the motor through the normal control system.
2. 🔒 Disable the servo drive.
3. ⚡ Remove the main drive supply according to the machine procedure.
4. ⏳ Wait for the DC bus to discharge.
5. 🔍 Verify the absence of hazardous voltage.
6. 🔧 Remove the drive cover only after electrical isolation is confirmed.
7. 🛡️ Use ESD protection when handling the PCB.

⚠️ Do not remove the SV2CON2/3 while the servo drive is energized.

📖 Product Usage Instructions

The SV2CON2/3 should be regarded as an internal control PCB for a compatible B&R drive assembly.

It is not normally configured like an independent PLC or X20 I/O module. Its operation depends on the surrounding B&R servo amplifier hardware, power electronics, feedback circuitry, motor connections, and higher-level control system.

When replacing the PCB, preserving the original configuration is important. Photograph the original board and connector layout before removal. If configuration switches, jumpers, memory devices, or removable components are present, compare them carefully with the replacement.

After installation, verify the drive’s startup diagnostics before attempting full-speed operation.

🔍 Inspection & Maintenance

Before accepting a replacement board:

• Verify the B&R identification label.

• Confirm SV2CON2/3.

• Confirm 050003169-03 where applicable.

• Inspect PCB tracks and solder joints.

• Check connectors for oxidation.

• Check for signs of overheating.

• Check mounting holes for damage.

• Verify the PCB revision.

• Check whether the unit has previously been repaired.

• Perform a controlled functional test with the compatible drive.
