Delta ASD-CNSC0050 ASDA-A2 CN1 50-Pin I/O Connector

Description

Key Technical Specifications

Delta’s ASDA documentation specifically identifies ASD-CNSC0050 as the I/O Signal Connector for the CN1 interface. The ASDA-A2 manual also identifies the 3M 10150-3000PE and 10350-52A0-008 components associated with this connector.

DigiKey currently classifies ASD-CNSC0050 as a 50-pin solder connector kit, for use with the ASDA-A2 series, and lists the manufacturer’s part status as obsolete.

Product Introduction

The Delta ASD-CNSC0050 is a 50-pin I/O signal connector used at the CN1 interface of Delta ASDA-A2 servo drives. It provides the physical termination point for the drive’s control and I/O signals and is not itself a servo drive, communication module, or preassembled signal cable.

This part is particularly relevant when an existing ASDA-A2 installation needs a replacement CN1 connector or a new field-wiring termination. Delta lists ASD-CNSC0050 among its ASDA optional connectors, while current distributor data identifies the part as obsolete.

Installation & Configuration Guide

Stage 1: Pre-Installation Preparation — Approximately 10 minutes

⚠️ Safety First: The connector carries servo-drive control signals. The associated ASDA drive can contain hazardous DC-bus voltage even after incoming power has been removed. Follow the exact discharge and isolation procedure for the installed ASDA drive.

1. Stop the servo system and place the machine in a safe state.
2. Apply the plant’s lockout/tagout procedure.
3. Remove drive power and verify the required discharge period from the applicable ASDA manual.
4. Verify hazardous voltage is absent using an appropriately rated meter.
5. Prepare:
   • ESD wrist strap
   • PH1 screwdriver
   • Multimeter
   • Wire labels
   • Small soldering tools if rebuilding the connector
   • Smartphone/camera
6. Photograph the existing CN1 connector and every wire position.
7. Record the exact ASDA drive model and revision before removing the connector.
8. Back up the servo parameter configuration where applicable.

❗ Do not identify wires by color alone. CN1 wiring depends on the actual ASDA model and application. Use the drive’s terminal assignment and the existing installation documentation.

Stage 2: Removing the Old Connector — Approximately 5 minutes

1. Confirm the drive is electrically isolated.
2. Photograph the connector from several angles.
3. Label each conductor.
4. Record the pin number associated with every conductor.
5. Remove the CN1 connector from the drive.
6. Inspect the connector for:
   • Bent contacts
   • Cracked housing
   • Loose solder joints
   • Corrosion
   • Damaged cable strain relief
7. Keep the old connector until commissioning is complete.

The documentation identifies ASD-CNSC0050 specifically as the CN1 I/O Signal Connector, so replacing it should not be treated as a generic 50-pin connector substitution.

Stage 3: Installing the New Connector — Approximately 10 minutes

1. Verify the replacement is .
2. Compare the connector mechanically with the removed unit.
3. Confirm the 50-pin arrangement.
4. If transferring an existing cable, reproduce the documented pin-to-wire assignment exactly.
5. Inspect solder joints for bridges or cold joints.
6. Check for exposed conductor strands that could contact adjacent pins.
7. Verify shield and signal-ground connections against the applicable ASDA wiring diagram.
8. Secure the connector and cable so mechanical force is not transferred directly to the solder joints.
9. Connect the assembly to CN1 without forcing the connector.

Delta documentation identifies the associated connector components as 3M 10150-3000PE and 10350-52A0-008.

Self-check:

• verified
• 50-pin configuration verified
• CN1 location verified
• Every wire documented
• Solder joints inspected
• No pin-to-pin shorts
• Shielding checked
• Connector mechanically secured

Stage 4: Power-On & Testing — Approximately 10 minutes

1. Perform a continuity and short-circuit check before applying power.
2. Confirm that no adjacent CN1 pins are unintentionally bridged.
3. Reconnect the connector to the ASDA drive.
4. Restore power according to the machine’s approved startup procedure.
5. Check the servo drive for abnormal alarms.
6. Verify the drive communicates with the controller.
7. Test the required digital inputs and outputs individually.
8. Verify emergency-stop, servo-enable, limit, and other safety-related signals according to the machine’s approved commissioning procedure.
9. Confirm command and feedback behavior before enabling motion.
10. Perform a controlled low-risk motion test before returning the machine to production.

⚠️ Important: is a connector accessory, not a programmable electronic module. There is no firmware to “match” in the connector itself. Compatibility depends primarily on the ASDA drive model, CN1 pin assignment, connector construction, and wiring.

Technical Pitfalls — What Usually Causes Rework

❗ 1. Confusing the connector with a complete cable

is documented as an I/O Signal Connector. Delta lists separate cable products such as ASD-CARS0003 and encoder cables. Do not order a connector when the installation requires a complete preassembled cable.

❗ 2. Assuming every 50-pin connector has the same pinout

A 50-pin mechanical interface does not automatically establish electrical compatibility. The CN1 assignment must match the actual drive model and application.

❗ 3. Soldering without documenting the original wiring

This is an easy way to create a fault that looks like a servo-drive problem. Photograph and record the original pin assignment before removing the old connector.

❗ 4. Ignoring obsolete-part status

DigiKey lists as obsolete, so procurement should confirm remaining stock and condition rather than assuming normal factory availability.

❗ 5. Testing motion before checking control signals

Do not immediately command motor movement after replacing CN1 wiring. First verify enable, limit, emergency-stop, command, and other application-specific signals.

Quality-Control Inspection for Replacement Stock

For a replacement , a useful incoming inspection should include:

1. Part-number verification: Confirm marking and connector configuration.
2. Visual inspection: Check the housing, contacts, solder terminals, and insulation for damage.
3. Mechanical inspection: Verify mating dimensions against the ASDA drive’s CN1 interface.
4. Electrical inspection: Perform continuity and isolation checks appropriate to the connector assembly.
5. Pin verification: Compare the connector against Delta’s documented CN1 interface before installation.
6. Final QC: Record inspection date, part condition, and test result.

For surplus stock, the supplier should explicitly state whether the item is New Original/New Surplus or Refurbished (tested). Do not treat “unused” and “factory sealed” as interchangeable descriptions.

Frequently Asked Questions (FAQ)

1. What is Delta ?

is a 50-pin I/O signal connector for the CN1 interface of Delta servo drives. It is an accessory connector rather than a servo amplifier or communication module.

2. Is compatible with ?

Yes. Delta’s documentation explicitly lists as the CN1 I/O signal connector.

3. Is a complete cable?

No. It is a connector/connector kit. Delta separately lists communication, encoder, motor, and other cable assemblies. If you need a finished cable assembly, verify the required cable part number rather than ordering .

4. Is obsolete?

Yes. DigiKey currently lists the manufacturer’s part status as Obsolete. Delta documentation nevertheless continues to identify among the optional connectors for its ASDA servo platforms.

5. What connector components are associated with ?

Delta’s manual identifies 3M 10150-3000PE and 3M 10350-52A0-008 in connection with the CN1 connector. Verify the exact mechanical and termination arrangement against the connector you are replacing.

6. Can I substitute another 50-pin SCSI connector?

Do not make that substitution based solely on the pin count. Mechanical dimensions, keying, contact arrangement, termination method, mating geometry, and pin numbering all need to match. For a production servo system, use the documented Delta connector or a replacement explicitly verified for the ASDA CN1 interface.

7. What should I verify before ordering ?

Verify the part number, the installed ASDA drive family/model, CN1 interface, 50-pin configuration, connector condition, and whether you need only the connector or a complete cable assembly. Because the part is obsolete, also confirm whether the offered unit is New Original/New Surplus or Refurbished (tested) before placing the order.
