Yaskawa Error Code — A910 Link
Predictive software calculates thermal curves based on exact duty cycles. Pn52B When to Seek Component Replacement
: The cycle time or load exceeds the motor's rated capacity. Wiring Issues
Note: Always consult the specific technical manual for your Yaskawa model (GA500, GA700, A1000, V1000) as parameter addresses can vary.
In Sigma 7 SERVOPACKs, the warning sensitivity is governed by the parameter . If this parameter is set too low (e.g., below the factory default of 20%), the drive will throw an A.910 code during entirely normal, safe operating profiles. 5. High Cabinet Temperatures or Hardware Failure
Unplug and re-plug the encoder connectors (CN2) on the SERVOPACK and at the motor end. Ensure they are locked and properly seated [Source: SES Automations ]. yaskawa error code a910 link
Check for adequate lubrication on linear guides and gears. Step 2: Inspect Wiring and Connections
Understanding how to diagnose and resolve this warning is crucial for minimizing downtime in automated systems utilizing Yaskawa Sigma Series servo drives. Anatomy of the A.910 Warning Across Servo Generations
Intermittent or high-resistance electrical connections force the drive to output higher current to maintain the required motor performance. Loose terminal screws, corroded pins inside the circular connectors, or internal cable fatigue mimic a high-torque demand. 2. Mechanical Jams and Restrictive Loads
Disconnection or scale contamination can simulate rapid torque spikes. Pn52B High-Resolution 24-bit Encoder Predictive software calculates thermal curves based on exact
: Regularly track the root-mean-square (RMS) torque percentage in your preventative maintenance checklists to spot mechanical wear before alarms trigger.
: Excessive load on the motor due to mechanical friction or a physical obstruction. Operating Conditions
In automated industrial environments, the is an Overload Warning that indicates a servo drive is dangerously close to exceeding its thermal or physical torque capacity. This critical warning acts as a preventive buffer, alerting operators before the system trips into a full-scale shutdown. Ignoring it inevitably triggers hard faults like A.710 (Instantaneous Maximum Load Overload) or A.720 (Continuous Maximum Load Overload) , which halt production lines abruptly to save system components from permanent destruction. 1. What is the Yaskawa A.910 Warning?
Faulty, damaged, or noisy encoder cable causing intermittent communication (link) errors. Loose terminals connecting the motor phases (U, V, W). 3. Incorrect Parameter Settings In Sigma 7 SERVOPACKs, the warning sensitivity is
The drive uses internal parameters to calculate when this code trips:
Start with the basics. Ensure all communication cables are securely seated in their ports. Check for sharp bends or crimps in the cable that might have damaged the internal copper or fiber. 2. Verify the Master Controller Status
The motor is encountering more physical resistance than it is designed to handle, often due to binding, friction, or an oversized load.
