A0788 fault in WEG CFW500 Drive

-
A0788 alarm in WEG CFW500 Drive indicates a High Level of the External PID Process Variable. This means the external PID feedback sensor reading has exceeded its maximum programmed threshold.

 Cause:

Parameter P1075 is programmed for 1, and the process variable of the external PID controller remained above the value programmed in P1078 for the duration set in P1079.

Remedy:

Verify process line sensors. Check parameter thresholds set in P1075, P1078, and P1079.

Seeing A7991 on your Siemens drive? This alarm means Motor Data Identification is selected. Learn how to start the ID run or clear the alarm in our guide.   Solving Siemens Alarm A7991: Motor Data Identification Selected If you are looking at your Siemens SINAMICS G120 or S120 drive and the display is flashing A7991 , you are in the final stages of setting up your motor. In the Siemens manual, this is defined as "Motor data identification selected." This isn't a "broken" state. It is the drive's way of saying, "I'm ready to measure the motor's electrical traits, but I'm waiting for you to tell me when to start." Let's look at why this appears and how to clear it so you can get back to production. Why is Alarm A7991 Appearing? The A7991 alarm is triggered when Parameter P1900 (Motor data identification and speed controller optimization) is set to a value other than 0. ...

3210 DC bus overvoltage fault in lenze i550 drive

-
Fault Code 3210 in a Lenze i550 drive indicates a DC bus overvoltage fault . This means the voltage on the DC bus within the drive has exceeded its safe operating limit. Potential Causes Drive Internal Components: A fault in the drive's rectifier, smoothing capacitor, or control circuitry. Solution: This often requires professional inspection and repair or replacement of the faulty component. Power Supply Issues: Excessive AC voltage input to the drive. Solution: Check the power supply for voltage fluctuations or overvoltage conditions. Motor Issues: A short circuit or other fault within the motor can cause excessive back EMF, leading to DC bus overvoltage. Solution: Inspect the motor for any signs of damage or malfunction. Drive Configuration Issues: Incorrectly configured drive parameters, such as excessive regeneration or improper motor data. Solution: Review and adjust drive parameters to match the motor and application requirements. Troubleshooting Steps Check Power ...
