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.

In some frequency converters, there is a so-called "fire mode", when the frequency converter works despite problems, up to breakdown and fire. A wrong value will only be detected if the error is such that the calculated slip is greater than 4 times the rated slip of the motor.

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. Detection is more sensitive when the drive is not running and can produce false positives.

For the most recent fault identified by parameter , the drive stores additional data in parameters … to aid in troubleshooting a problem. Frequency controllers come already with built-in energy efficiency features. Is this content inappropriate? For example, if a fault occurs the frequency converter can stop or continue to run by issuing a fault message. The thermistor measuring the internal temperature of the drive is open or shorted. A wrong value will only be detected if the error is such that the calculated slip is greater than 4 times the rated slip of the motor. The thermistor measuring the internal temperature of the drive is open or shorted. Press SAVE. Using the control panel in Parameters mode, select parameter The OL message may be caused by the internal electronic thermal motor protection, or by the motor being overloaded mechanically over torque. The drive monitors for ground faults while the drive is running and while the drive is not running. SI SI
