Yaskawa Error Code A910 Exclusive

In Yaskawa servo drive systems, the code is classified as an Overload Warning

. Unlike a hard fault, a warning indicates that the system is approaching an operational limit but has not yet tripped a protective shutdown. Understanding the A.910 Warning

The A.910 warning specifically serves as a "pre-alarm" for more severe overload conditions. It is designed to alert operators before the drive triggers the following fatal alarms: : Overload – High Load. : Overload – Low Load. Yaskawa America

If the conditions causing A.910 are ignored and operation continues, the drive will eventually shut down with one of the above errors to protect the motor and internal circuitry. Common Causes Excessive Load

: The torque required by the application is consistently exceeding the motor's rated capacity. High Ambient Temperature : If the environment around the motor or drive exceeds

), the system's ability to dissipate heat is reduced, leading to premature overload detection. Mechanical Issues

: Increased friction in the mechanical system—such as worn bearings, jammed gears, or lack of lubrication—forces the motor to work harder than normal. Incorrect Gain Settings

: Aggressive servo gain settings can cause the motor to "hunt" or vibrate, drawing excessive current and triggering an overload warning. MachMotion Troubleshooting and Solutions Check Load Ratios : Use the monitor function (typically

for accumulated load ratio) to verify the actual percentage of the motor's capacity being used. If it is consistently near or above 100%, the application may require a larger motor or a change in duty cycle. Verify Environment

: Ensure that the cooling fans on the drive are functional and that there is adequate ventilation in the control cabinet. Inspect Mechanics

: Disconnect the motor from the load and check if the mechanical components move freely by hand. Tune the Servo : If vibration is present, use the Yaskawa SigmaWin+ software

to perform autotuning or manually adjust gains to stabilize the system. yaskawa error code a910 exclusive

In the context of Yaskawa servo drives (such as the Sigma-7, Sigma-5, and Sigma-3 series), error code A.910 is a warning indicating an Overload condition.

This code is distinct from a hard "alarm" (which would stop the motor); instead, it serves as a preemptive alert that the system is approaching the thresholds for more severe overload alarms, specifically A.710 (Instantaneous Maximum Load) or A.720 (Continuous Maximum Load). Root Causes of A.910

The warning is typically triggered when the drive detects the motor is working harder than its rated capacity. Common reasons include:

Mechanical Resistance: Excessive friction or a jam in the connected machinery that forces the motor to draw more current to maintain speed.

Operating Conditions: High-frequency acceleration/deceleration cycles or a load inertia that exceeds the motor’s design limits.

Parameter Settings: The overload warning level (parameter Pn52B) may be set too low for the specific application.

Wiring Issues: Incorrect or loose contact in the servomotor or encoder wiring can lead to inefficient operation and false load readings.

Environmental Factors: High ambient temperatures (exceeding 40–55°C) within the control panel can reduce the drive's thermal overhead. Troubleshooting & Solutions Yaskawa Servo Drive Alarm Codes Guide | PDF - Scribd

3. Parameter Conflict (Digital Operator vs. PLC)

This occurs frequently during commissioning. The drive is receiving conflicting commands regarding who is the "Master."

3. Pin Corrosion or Micro-Fretting

The RJ45-style or 14-pin connector between the operator and drive is not gold-plated on standard models. In environments with even trace levels of hydrogen sulfide (paper mills, wastewater treatment), microscopic corrosion increases contact resistance. The drive senses this increased resistance as a "disconnected operator" even though the clip feels tight. In Yaskawa servo drive systems, the code is

What does A910 mean?

"Momentary Power Failure" or "Undervoltage during run" The drive detected that the DC bus voltage dropped below the undervoltage detection level while the motor was running.

Conclusion

The Yaskawa A910 error serves as a guardian against unintended

The Yaskawa error code A910 (often displayed as A.910) indicates a "Momentary Power Loss" or "Undervoltage during Run" fault on Yaskawa AC drives (e.g., A1000, V1000, J1000, GA500, GA800 series).

1. The "Hard" Stop: Baseblock (BB) is Active

This is the most common cause. Baseblock is a state where the drive disables its output transistors, essentially disconnecting the motor from power.

Primary Causes of Yaskawa Error A910

To fix this exclusively, you must understand the root physics behind the error. Here are the four definitive causes:

Conclusion

Yaskawa Error Code A910 is “exclusive” because it points directly to a hardware failure in the drive’s charging path. While software errors can often be tuned out, A910 demands a hardware-level response. If you see this code, plan for drive replacement or send the unit to a Yaskawa-authorized service center. Do not attempt to bypass the pre-charge circuit – doing so can cause explosive capacitor failure.

Understanding Yaskawa Error Code A910: Exclusive Access

Yaskawa is a well-known Japanese company that specializes in the production of industrial robots, servo drives, and other automation equipment. Their products are widely used in various industries, including manufacturing, automotive, and food processing. However, like any complex machinery, Yaskawa devices can sometimes encounter errors, one of which is the A910 error code. This article aims to provide an in-depth look at the A910 error code, specifically focusing on its meaning, causes, and troubleshooting steps.

What is Yaskawa Error Code A910?

The A910 error code is a specific fault code generated by Yaskawa's servo drives and robots. When this error occurs, it typically indicates that there is an issue related to the system's exclusive access. The error code A910 suggests that the device is experiencing a problem with accessing a particular resource or function that is currently locked or reserved by another process. The Conflict: You are trying to jog the
