Yaskawa Error Code A910 Exclusive

Verify that parameters such as Pn520 (Position Error Pulse Overflow) or others related to motor current are set correctly for your specific application.

Several factors can contribute to the occurrence of the A910 exclusive error code. Some of the most common causes include:

The simplest initial step is to power down the drive completely. Wait until the internal DC bus capacitors fully discharge (the charge LED turns off completely), then restore power. This resets the internal microprocessors and clears any transient buffer overflows. Step 2: Check and Isolate Option Cards

Lack of lubrication on linear paths or bearings significantly increases the torque required to sustain motion. 2. Aggressive Motion Profiles

Check all connectors (military-style connectors, circular plugs, etc.) to ensure they are seated correctly and fastened tightly. Step 3: Monitor Motor Current and Load Factor Verify that parameters such as Pn520 (Position Error

: Triggered when the motor operates continuously under a torque exceeding its rating for an extended period. Core Technical Causes of Yaskawa A.910

Yaskawa error code A910 is a straightforward alert. It signals that the motor is on a path to overload. By treating it as a diagnostic opportunity for early intervention, maintenance teams can avoid more severe failures, costly downtime, and lost productivity.

Binding along linear guide rails forces the motor to fight the machine structure itself. Wait until the internal DC bus capacitors fully

In Yaskawa terminology, the "A" prefix designates an or Warning rather than a fatal trip. The A.910 code specifically points to Motor Overload . The drive calculates a thermal load based on the motor's current and operating time. When this value reaches the warning level (usually 80% to 100% of the maximum allowable overload), the A.910 warning triggers.

: Verify all motor and encoder connections are secure and correct.

Intermittent or incorrect connections in the U, V, and W motor power lines or the encoder feedback cable cause phase imbalances. If a single phase loses full connectivity due to a frayed wire or loose terminal screw, the motor must pull excessive current from the remaining phases to compensate, causing rapid internal heat generation. 4. Undersized System Capacity or Aggressive Duty Cycles

To resolve the A.910 error and prevent it from becoming a critical A.710 or A.720 fault, follow these steps:

The code indicates that the drive's internal algorithms have detected an operation that exceeds the rated overload protection characteristics of the motor. Essentially, the drive is "warning" you that if current conditions continue, the motor or the SERVOPACK will overheat. Common Causes of the A.910 Alarm
