Well, there are several faults in relation with winding or cabling problems but none of those have appeared so far.
These are some of them. But as you know, I only had the overcurrent fault and it was not even when accelerating (Because the drive has three separate overcurrent alarms for acceleration, deceleration and during operation). Fu. 041 The motor fails to be connected when the motor parameters are identified. The motor fails to be connected when the motor parameters are identified. Connect the motor. Fu.042 U phase output is disconnected or the parameters are seriously unbalanced 1. The lead from frequency inverter to motor is disconnected. 2. The driving or control panel of the frequency inverter is faulty. 3. The three-phase winding of the motor is faulty. 1. Eliminate peripheral faults 2. Seek for manufacturer’s support 3. Eliminate motor faults. Fu.043 V phase output is disconnected or the parameters are seriously unbalanced 1. The lead from frequency inverter to motor is disconnected. 2. The driving or control panel of the frequency inverter is faulty 3. The three-phase winding of the motor is faulty 1. Eliminate peripheral faults. 2. Seek for manufacturer’s support 3. Eliminate the fault of motor. Fu.044 W phase output is disconnected or the parameters are seriously unbalanced 1. The lead from frequency inverter to motor is disconnected. 2. The driving or control panel of the frequency inverter is faulty. 3. The three-phase winding of the motor is faulty. 1. Eliminate peripheral faults. 2. Seek for manufacturer’s support 3. Eliminate the fault of motor. Fu.051 U phase current is detected faulty (sensor or circuit) 1.The current sensor or circuit is damaged. 2. The auxiliary power supply is faulty. 3. The control and driving panel are improperly connected. Seek for manufacturer’s support. Fu.052 V phase current is detected faulty (sensor or circuit) 1.The current sensor or circuit is damaged. 2. The auxiliary power supply is faulty. 3. The control and driving panel are Improperly connected. Seek for manufacturer’s support.
