Solving ABB ACS355 Alarm A5013: Why Your Panel Control is Disabled

If you are trying to start your ABB ACS355 drive from the keypad and the screen keeps flashing A5013, it can be quite frustrating. You press the green button, but nothing happens.

In the ABB manual, A5013 is defined as "Panel control is disabled because start inhibit is active." In simple terms, the drive’s internal safety logic has locked the "Start" button on your panel because it is waiting for a specific condition to be met first. It’s a safety feature, not a hardware failure.

Common Causes of the A5013 Alarm

The "Start Inhibit" function is designed to prevent a motor from starting unexpectedly. The A5013 code usually pops up for one of these reasons:

  • Active Emergency Stop: An E-stop button is pushed in, or the emergency stop circuit is open.
  • 3-Wire Control Mismatch: You are using a 3-wire start/stop macro, and the "Stop" signal is currently missing.
  • Run Enable Missing: The drive is waiting for a "Run Enable" signal (Parameter 1601) before it will allow a panel start.
  • Control Mode Switch: You just switched from Remote (REM) to Local (LOC) control while a start command was already pending.

Step-by-Step Troubleshooting Guide

1. Check the Emergency Stop (E-Stop)

The most common cause for A5013 is an active emergency stop command.

  • Check your physical E-stop buttons around the machine. Are any of them pushed in?
  • Check Parameter 2109 (EMERG STOP SEL). This tells the drive which input is watching for an emergency stop. If this input is open, the drive will inhibit any panel start.

2. Inspect the "Run Enable" Signal

The ACS355 often requires a "Run Enable" signal before the panel will work.

  • Check Parameter 1601 (RUN ENABLE). By default, this might be looking for a signal on Digital Input 4 (DI4). If DI4 is off, the panel is disabled.
  • If you don't use a Run Enable signal, you can set Parameter 1601 to [0] NOT SEL to allow the panel to work freely.

3. Look at Start Inhibit (Parameter 2108)

There is a specific parameter that controls this entire behavior.

  • Check Parameter 2108 (START INHIBIT).
  • If this is [1] ON, the drive will prevent a start if a fault was just reset or if the control location was just changed.
  • To clear the inhibit, you usually just need to cycle your start command (turn the start signal off and then back on).

4. Verify Control Macro Settings

If you are using a 3-wire macro, the drive requires a "Stop" contact to be closed at all times. If that contact is open, the drive thinks you are holding the "Stop" button down, which inhibits the panel from starting.

How to Clear Alarm A5013

  1. Reset any active Emergency Stop buttons.
  2. Ensure the Run Enable signal is present at the drive terminals.
  3. If you just changed from Remote to Local mode, remove the start command and then try pressing the Start button on the panel again.
  4. Verify Parameters 1001 and 1002 to ensure the control sources (EXT1/EXT2) aren't conflicting with your panel commands.

Summary

The ABB ACS355 A5013 alarm is a guardrail. It's the drive's way of saying, "I won't start until I know it's safe." Usually, it’s just a pushed-in E-stop or a missing signal on your DI terminals. Check your safety circuit, verify Group 16 and 21 parameters, and you'll have your keypad control back in seconds.

Fault Code FF06 in a Lenze i550 drive indicates a motor overspeed fault . This means the motor connected to the drive is spinning at a speed that exceeds its rated maximum speed. Potential Causes Drive Configuration Issues: Incorrectly set maximum speed limit or frequency. Solution: Verify and adjust drive parameters to match the motor's specifications. Mechanical Problems: Jamming or Binding: Obstructions in the mechanical system can cause the motor to accelerate beyond its rated speed. Loose Coupling: A loose coupling between the motor and the driven load can lead to overspeed. Solution: Check for mechanical obstructions, ensure proper alignment, and tighten couplings as needed. Sensor Issues: A faulty speed sensor or incorrect sensor calibration can provide inaccurate speed readings, leading to overspeed. Solution: Verify the sensor's functionality, calibrate it if necessary, or replace it if faulty. Drive Internal Components: A fault within the drive's contr...

7180 Motor overcurrent fault in lenze i550 drive

-
Fault Code 7180 in a Lenze i550 drive indicates a motor overcurrent fault . This means the motor connected to the drive is drawing more current than its rated capacity, which can lead to overheating and potential damage. Potential Causes Overloaded Motor: The motor is being asked to do more work than it's designed for. Solution: Reduce the load on the motor or ensure it's rated for the required power. Mechanical Issues: Jamming: The motor or its connected machinery might be jammed, causing excessive current draw. Friction: Increased friction due to misalignment or worn components can lead to higher currents. Solution: Check for mechanical obstructions, ensure proper alignment, and replace worn parts if necessary. Electrical Problems: Short Circuit: A short circuit within the motor windings can cause excessive current. Incorrect Wiring: Improper connections can lead to overloading. Solution: Inspect for short circuits, verify wiring diagrams, and correct any issue...
