ABB Motion Drives Error trouble shooting manual AN00267

What this Document contains

If you have followed all the instructions in this manual in sequence, you should have few problems installing the

ABB Servo Drives. If you do have a problem, this document will help you to navigate then diagnose and resolve

the problem. The following pages contain information on how to understand and resolve issues that can occur.

Before we get to this it’s important to first discuss the fault diagnosis system used in ABB Motion products.

Problem diagnosis

There are 3 ways to get information on the faults that have occurred;

• In Mint WorkBench, connect to the drive and use the Error Log tool to view recent errors, get the descriptions

and then check the help files for more information.

• The drive status display indicates errors and general status information. When an error occurs, the drive

displays a sequence starting with the symbol “E” or “b”, followed by the five-digit error code.

• The drive also has two Network status LEDs that indicate the status of a used RTE master. You can check

the drives hardware manual for more information on how to diagnose the LED status.

How to reset faults

The drive can be used in different configurations so, to answer this question we must first consider which

configuration we are using;

• In Analog Mode the user can set RESETINPUT(0) = [input] or in parameters group: “Error Handling >

Reset Input” to a Digital input.

• In Direct mode if the drive is running a mint program and it goes into an error state, it will automatically try

to call the ONERROR event.

• If configured as a DS402 RTE Slave, the drive is using the DS402 state machine so disabling and re

enabling the drive will reset any active error, though ts best to issue a reset first.

Error categories

Controllers use an error handling system that allocates a unique number for each error. This means that an

error code does not need to be deciphered to determine exactly which individual error has occurred.

Errors are recorded in two ways:

• Error List: This is designed to be manipulated by the Mint program. The controller's error list can store up to

256 entries on MicroFlex e190 and MotiFlex e180.

• Error Log: This is a historical record of errors and is displayed in Mint WorkBench using the Error Log tool.

On MicroFlex e190 and MotiFlex e180. 5 KB of memory is reserved for the error log, where each error is

dynamically sized. This allows approximately 100 or more errors to be stored.

Entries in the error list can be viewed by type or sequentially, for which there are additional keywords (shown in

brackets in the following lists). Errors are arranged in several categories, with each error having a unique code.
