代码 HCA: Current Alarm

Code type: Alarm / minor fault Manual section: Yaskawa A1000 Troubleshooting Load is too heavy. Either reduce the load for applications with repetitive operation (repetitive stops and starts, etc.), or replace the drive. Acceleration and deceleration times are too short. - Calculate the torque required during acceleration and for the inertia moment. - If the torque level is not right for the load, take the following steps: - Increase the acceleration and deceleration times (C1-01 through C1-08). - Increase the capacity of the drive. A special-purpose motor is being used, or the drive is attempting to run a motor greater than the maximum allowable capacity. - Check the motor capacity. - Use a motor appropriate for the drive. Ensure the motor is within the allowable capacity range. The current level increased due to Speed Search after a momentary power loss or while attempting to perform a fault restart. The alarm will appear only briefly. There is no need to take action to prevent the alarm from occurring in such instances.
