The fault name is shown in long form along with some possible causes and corrective actions that may be taken. Check for and correct:.

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.

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. The message reappears after a few seconds if the control panel is not touched and the fault is still active. Flashing green — alarms For less severe errors, called alarms, the diagnostic display is advisory. Alarm messages disappear from the control panel display after a few seconds. The message returns periodically as long as the alarm condition exists.

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.

The ACS frequency converter is equipped with: built-in electromagnetic compatibility filter EMC ; depending on the power - choke with variable inductance on the cover of multiple current or choke on the input of the drive allows to reduce to the maximum the level of interference generated by the converter and increases insensitivity to the instability of the mains ; connection terminal box, allowing to make the attachment of cables to the body of the drive with the simultaneous grounding of the shields; a wide set of integrated defenses, allowing almost always avoiding the defect of the drive itself, the motor it controls, and the device; macros to control the external scientific and technical parameter using one of the two integrated PID controllers; 2 user macros and 8 stereotype macros; built-in program to control a pumping station with up to 4 pumps; built-in Modbus RTU protocol RS interface. Verify that is PARS not zero, and depending on value or is not zero. Press EDIT. Carousel Previous. Loads with variable and constant torque. Culture Documents. We have listed only the main fault messages. This message is related to the previous one and some extent duplicates it. These codes are not used as of the publication of this manual. A communication-related problem has been detected on the fiber optic link between the control and OINT boards. Detection is more sensitive when the drive is not running and can produce false positives. 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.

Abb acs frequency inverters generally have several nice design features: Built-in Modbus protocol. The Safety instructions on the first pages of this manual must be followed. This message indicates that the frequency converter output current has exceeded the allowable value. Configuration Block Drive ID is not valid. This alarm warns that a Motor Stall fault trip may be near. Module No. A A In some frequency converters, there is a so-called "fire mode", when the frequency converter works despite problems, up to breakdown and fire. If a fault occurs, the motor stops to avoid damage to the frequency converter itself or other equipment. The meaning is protocol dependent. This problem can be solved in several ways - increase the braking time, apply a braking resistor, disable braking stopping the motor at free coasting , raise the limit level of overvoltage limitation if possible. Current measurement is out of range. Current measurement is out of range.
