Increase the "S-curve" or ramp times to reduce the instantaneous torque required from the motor. 3. Monitor Real-Time Data Use the SigmaWin+ software to monitor the Torque Reference .

Unlike critical alarms, the servo amplifier will continue running the motor while this warning is active. This design allows the controlling PLC or automation system to finish its current cycle or execute a controlled deceleration routine rather than triggering an abrupt, damaging emergency stop. Primary Causes of Yaskawa Error Code A910

Ensure U, V, and W power phases and encoder cables are secure. yaskawa error code a910

The drive uses one or three current sensors (depending on phase count). Over time, these sensors can drift due to thermal stress, electrical spikes, or simply age. When the sensor outputs a non-zero signal at zero current, the A910 alarm trips.

Check the . If this factor is consistently resting above 80% to 90% during standard cycles, your motor is simply undersized for the application, or the cycle is too demanding. Step 3: Review and Adjust Motion Profiles

Mastering the Yaskawa Error Code A910: Causes, Solutions, and Preventive Maintenance If you have already tried checking the motor

Keep the cooling fins on both the SERVOPACK and the servo motor clean. Dust buildup acts as an insulator, trapping heat and accelerating thermal overload calculations.

Taking action while the drive is still in the A910 stage saves you from a sudden line stoppage. 2. Primary Causes of Yaskawa Error Code A910

Inspect encoder cable connections for noise-related issues. If the system is in a high-noise environment, ensure the encoder cable is shielded, and that the shield is grounded properly. 3. Review Parameter Settings Pn402cap P sub n 402 (Overload Warning Level): Check if this setting is too low. Pn400cap P sub n 400 Pn401cap P sub n 401 Unlike critical alarms, the servo amplifier will continue

: Ensure all motor and encoder cable connections are secure and correctly pinned.

The most frequent cause of an overload warning is a change in the physical environment of the machinery. If the motor must push harder than it was originally designed to, its current draw spikes. Common culprits include: Misaligned linear guides or ball screws. Lack of lubrication on slides, bearings, or gears. Mechanical jams, debris, or a failing gearbox. 2. Excessive Duty Cycles and Demanding Profiles

The A.910 code is a preemptive alarm. It means that the current load on the servo motor is too high, often exceeding of the motor's rated torque for an extended period. Overload Warning (Pre-alarm).

The motor is running, but it is doing much less work than expected—as if the load has been disconnected or broken.
