Staring at Fault 5 on your PowerFlex 700? This Overvoltage guide explains why the DC bus spikes, how to check braking resistors, and the parameters to adjust. If you are standing in front of an Allen-Bradley PowerFlex 700 and the HIM module is flashing Fault 5 (Overvoltage) , your drive is protecting itself from a surge of electrical energy. In simple terms, the "DC Bus"—the drive's internal reservoir of power—has become over-pressurized. For a standard 480V drive, this usually means the voltage has spiked above 810V DC . To prevent the capacitors from failing, the drive trips. Let’s look at how to find the source of that extra energy. Common Causes of Overvoltage in PowerFlex 700 When a PowerFlex 700 trips on Fault 5, it’s usually due to one of these three scenarios: Regeneration (Deceleration): This is the #1 cause. When you try to stop a heavy load (like a fan or a centrifuge) too fast, the motor turns into a generator and...

ou3 fault in drive indicates  Over voltage in constant speed comes when the inverter's internal main circuit DC voltage to reach or exceed the specified value. Cause :   Over voltage in constant speed comes when the inverter's internal main circuit DC voltage to reach or exceed the specified value. Solutions:  The protection circuit is activated to stop the inverter output. The circuit may also be activated by a surge voltage produced in the power supply system. Power supply abnormal. Check the input power source. Large load inertia. Add suitable braking devices.

Staring at Er-11 on your Yaskawa GA500? This Auto-Tuning error means your motor data is mismatched. Learn how to check parameters and fix the error today. If you are in the middle of commissioning a new Yaskawa GA500 and the keypad suddenly displays Er-11 , you haven't broken the drive. This is a very specific error that happens during the Auto-Tuning process. In the Yaskawa manual, Er-11 is a Motor Data Error . It means the drive has taken the information you typed in (Amps, Voltage, Power) and compared it to its own internal calculations, and the two don't match. Essentially, the drive thinks the motor data is "illogical." Why Does Er-11 Happen? When the GA500 trips on Er-11, it is usually due to one of these three "Human" errors: Parameter Typos: You accidentally entered the wrong Rated Current or Rated Power (e.g., entering 50.0 Amps instead of 5.0 Amps). Unit Mismatch: You entered the motor power in Horse...

7510 FBA A communication Fault in ABB ACS880 Drive indicates cyclical communication between drive and fieldbus adapter module A or between PLC and fieldbus adapter module A is lost.   Cause   : Cyclical communication between drive and fieldbus adapter module A or between PLC and fieldbus adapter module A is lost. Solution:  1. Check status of fieldbus communication. See user documentation of fieldbus interface. 2. Check settings of parameter groups 50 Fieldbus adapter (FBA), 51 FBA A settings, 52 FBA A data in and 53 FBA A data out. 3.   Check cable connections. 4. Check if communication master is able to communicate.

Staring at SCF4 or SCF1 on your Schneider Altivar VFD? Learn how to diagnose IGBT short circuits, test your motor, and clear the fault safely.   Solving the Schneider Altivar Short Circuit Fault: SCF1, SCF3, and SCF4 If you are working with a Schneider Altivar drive and the screen suddenly turns red with an SCF fault , your first instinct might be to panic. These are "Hard Faults," meaning the drive has detected a massive rush of current and shut down in milliseconds to prevent a fire or total hardware failure. On the Schneider platform, these codes break down as follows: SCF1: Motor short circuit. SCF3: Ground fault (current leaking to earth). SCF4: IGBT short circuit (Internal power component failure). SCF5: Short circuit detected during motor start-up. What is an IGBT and Why Does it Trip? The IGBT (Insulated-Gate Bipolar Transistor) is the high-speed switch inside the drive that creates the variable freq...

Staring at F0035 on your ABB ACS550? Learn why the Output Wiring Fault occurs, how to check your terminals, and how to fix your VFD safely.   Solving ABB ACS550 Fault F0035: The "Wiring Error" Guide If you are looking at your ABB ACS550 and the display is flashing F0035 , the drive has detected an "impossible" electrical condition. It thinks that the power meant for the motor is actually coming from the power grid—or vice versa. In the ACS550 series, F0035 is the Output Wiring Fault . It’s a high-level safety trip designed to prevent the drive's internal transistors (IGBTs) from exploding. Let's look at why this happens and how to fix it without damaging your hardware. Common Causes of the F0035 Fault When an ACS550 trips on F0035, it’s usually one of these three real-world issues: Input/Output Swap (The "Oops" Moment): The most common cause on new installations. The power lines (L1...

Seeing A5014 on your ABB ACS550? This "Local Lock" alarm prevents you from using the keypad buttons. Learn how to unlock your drive using Parameter 1606.   How to Fix ABB ACS550 Alarm A5014: Unlocking the Keypad Are you trying to switch your ABB ACS550 to "Local" mode or hit the "Start" button, only to have the screen flash A5014 at you? It feels like the drive is ignoring you, but there is a very specific reason for this behavior. In the ABB manual, A5014 stands for "Local Lock." It means the drive has been programmed to disable the keypad's LOC/REM , Start/Stop , and Direction buttons. It is a software "padlock" usually put in place by engineers to prevent operators from taking manual control of a critical process. Let’s look at how to take that lock off. Why is the A5014 Alarm Appearing? The ACS550 allows for a "Local Lock" function to be assigned to a specific p...
