A910 Link |work|: Yaskawa Error Code

The Yaskawa A.910 error code acts as a preemptive overload warning, signaling potential issues before a full system shutdown occurs. Common causes include mechanical binding, incorrect wiring, or parameter settings that require adjustment. For troubleshooting guides tailored to different Yaskawa series, visit Click2Electro.

While "A910" is commonly mistaken for a Yaskawa code, it is actually a frequent alarm on Siemens SINAMICS and Micromaster drives. On these systems, indicates that the Vdc-max controller has been deactivated because the DC-link voltage has exceeded its limits. Troubleshooting the A910 Alarm

The drive issues this warning when it can no longer keep the DC-link voltage within a safe range, often causing the motor to go into regenerative mode. Check Input Voltage

: Ensure the main supply voltage (parameter P0210) is within the drive's rated range and not permanently too high. Active Loads

: Verify if the motor is being driven by an active load, which pushes the system into regenerative mode. High Inertia

: Check for high load inertias during deceleration. If the ramp-down time is too short, the DC-link voltage will spike. Parameter Settings : Ensure parameter

(Vdc controller configuration) is set correctly for your application. Related Yaskawa Fault Codes yaskawa error code a910 link

If you are certain you are working with a Yaskawa drive, you may be looking for one of these similar-sounding codes: Ad0 (Position Error Pulse Overflow)

: Often misread as A910, this occurs when the position error exceeds the allowable limit. A.81 (Encoder Disconnected) : A common alarm on Yaskawa SGDH ServoPacks. OL1 / OL2 (Overload)

: Indicates the motor or drive has exceeded its rated current capacity for too long. oH1 (Heatsink Overheat)

: The drive's internal temperature has exceeded safe levels.

Step 3: Verify Parameter Configuration

• Cause: Mismatch between the motor rated speed and drive settings.
• Check:
  • Verify F1-01 (Pulse Count). If your encoder is 1024 PPR but F1-01 is set to 2048, the drive thinks the motor is spinning twice as fast as it actually is.
  • Check b3-01. If the application requires the motor to be moving slightly at start (e.g., winders), you may need to increase the allowable overspeed level at start.

Step 1: Read the Sub-Error (Critical)

The A910 alarm has a sub-code that tells you why the link failed. To access it: The Yaskawa A

1. Press the MENU button until you reach Alarm History.
2. Scroll to the A910 event.
3. Press DATA to view the sub-error.

Common sub-codes:

• A910-01: Option card not physically present (detected empty slot).
• A910-02: Option card detected but handshake timeout.
• A910-03: Power supply failure to the option slot.
• A910-04: Option card returned corrupted ID data.

Yaskawa Error Code A910: "Link" (Communication Error)

Error Type: Communication error between the drive and the keypad, option board, or host controller.

Common Causes:

• Loose or damaged communication cable (RJ45 or serial).
• Incorrect communication parameter settings (e.g., baud rate, node ID, protocol).
• Electrical noise interference.
• Faulty keypad, option board (e.g., SI-P3, SI-EM3), or drive hardware.

Typical Solutions:

| Step | Action | |------|--------| | 1 | Power cycle the drive – sometimes clears temporary comm glitches. | | 2 | Check connections – reseat keypad cable, option module, or network cable. | | 3 | Inspect for damage – replace any frayed or crushed cables. | | 4 | Verify parameters – ensure baud rate, parity, and stop bits match between drive and master. | | 5 | Reduce noise – separate control wiring from power cables; use shielded twisted pair cable. | | 6 | Test without option board – if error stops, the board may be faulty. | | 7 | Replace keypad or cable if error persists with local keypad only. |

Affected Yaskawa Series:
Common on V1000, J1000, GA700, GA800, U1000, and A1000 drives. Cause: Mismatch between the motor rated speed and

When to Call Yaskawa Support

You have exhausted all hardware and parameter checks. Contact Yaskawa Technical Support (1-800-YASKAWA in the US) if:

• A910 converts to F910 (Fault) immediately upon power-up.
• The drive control board shows visible burn marks near the option slot.
• You have replaced the option card twice and the error persists (points to a backplane issue).

Common causes

1. Physical layer issues

   • Faulty, loose, or damaged cables/connectors.
   • Incorrect cable type (e.g., using a straight cable where a crossover or shielded twisted pair is required).
   • Broken shielding or poor grounding causing EMI.

2. Power/boot sequencing

   • Devices powered in wrong order causing master/slave initialization failures.
   • Intermittent power to network interface modules.

3. Configuration mismatches

   • Incorrect communication parameters (baud rate, parity, stop bits).
   • Node/address conflicts or duplicate IDs on the bus.
   • Wrong protocol selection or incompatible firmware versions.

4. Network device failures

   • Failed network interface module (comms card) or I/O module.
   • Faulty master device, PLC, or switch/hub.

5. Topology & timing

   • Excessive network length, improper termination, or missing terminators.
   • Too many nodes or bus loading exceeding spec.
   • Network latency or timing violations (cycle time too short).

6. Software/firmware issues

   • Firmware bugs or mismatched firmware between devices.
   • Corrupted configuration or parameter set.
