At the bottom of this page there is a link to the diagnostics section of the user manual for the ABB ACH drive that gives further information for troubleshooting, if needed. Temperature is at or above limit. Motor is operating in the stall region. The drive monitors for ground faults while the drive is running and while the drive is not running.

Do not attempt any measurement, parts replacement or other service procedure not described in this manual. Such action will void the warranty, may endanger correct operation, and increase downtime and expense. All electrical installation and maintenance work described in this chapter should only be undertaken by qualified service personnel. The Safety instructions on the first pages of this manual must be followed. The form of the display depends on the severity of the error. The fault code on the control panel display is temporary.

In the process of operation of the frequency converter, sooner or later problems related to its correct operation arise. Errors and failures can occur both when turning on setting the frequency converter and during its operation. If most errors occur, the inverter stops working. The reaction to some errors can be programmed. For example, if a fault occurs the frequency converter can stop or continue to run by issuing a fault message. In some frequency converters, there is a so-called "fire mode", when the frequency converter works despite problems, up to breakdown and fire. To begin with, let's look at the typical abb alarm and error messages of frequency converters, which are displayed on the user's screen. Note that most of abb vfd alarm messages are transmitted via the communication channel if present to the controller and handled accordingly. This series of ABB frequency inverters guarantees the highest technical level, remarkable reliability characteristics, and ease of use. In the drive, the ACS principle of vector control is used, which allows you to get the highest motor torque episode at low speeds and improves the quality of the scientific and technical process. The ACS frequency converter is equipped with:. Code on the display: OC Over Current. This message indicates that the frequency converter output current has exceeded the allowable value. If this error occurs the first time you start the frequency converter, you should check if the rated current of the frequency converter matches the actual motor current - a short circuit may have occurred inside the motor. In some types of frequency converter, OC overload can be divided into 3 different errors - overcurrent during acceleration, under braking, running at a constant speed.
