Código oL2: Drive Overload

Code type: Fault Manual section: Yaskawa A1000 Troubleshooting Load is too heavy. Reduce the load. Acceleration or deceleration times are too short. Increase the settings for the acceleration and deceleration times (C1-01 through C1-08). V/f characteristics (voltage) are not suitable Set the V/f pattern setting parameters (E1-04 to E1-10) to match the motor characteristics. Drive capacity is too small. Replace the drive with a larger model. Overload occurred when operating at low speeds. - Reduce the load when operating at low speeds. - Replace the drive with a model that is one frame size larger. - Lower the carrier frequency (C6-02). Excessive torque compensation. Reduce the torque compensation gain (C4-01) until there is no speed loss but less current. Speed Search related parameters are set incorrectly. - Check the settings for all Speed Search related parameters. - Adjust the current used during Speed Search and the Speed Search deceleration time (b3-03 and b3-02 respectively). - After Auto-Tuning the drive, enable the Speed Estimation Speed Search (b3-24 = 1). Output current fluctuation due to input phase loss Check the power supply for phase loss.
