If the IGBT module’s heatsink is overheating in your Emerson DC Drives, it could be due to over-temperature; lower the ambient temperature. The vent might be obstructed, so clean the vent. Alternatively, the fan may not be working, so replace the fan. If none of these resolve the issue, the IGBT module might be abnormal, so seek service.
What to do if there is over-current in constant speed operation in Emerson EV2000-4T0075G/0110P DC Drives?
If your Emerson DC Drives experience over-current during constant speed operation, it might be due to a sudden load change, so try to reduce the change of the load. Also, check if the Acc/Dec time is too short and prolong it if needed. Examine the load for any abnormalities. Verify the AC supply voltage, as a low voltage can cause this issue. Finally, the drive's power might be insufficient, so consider selecting a drive with bigger power.
Why is there over voltage during deceleration in Emerson DC Drives?
If you're facing over voltage during deceleration with your Emerson DC Drives, the deceleration time may be too short, especially concerning generated energy; try prolonging the Dec time. Additionally, if the load generates energy or the load inertial is too big, consider using a suitable dynamic braking kit.
How to resolve over-current during deceleration in Emerson EV2000-4T0075G/0110P DC Drives?
If you're experiencing over-current during deceleration with your Emerson DC Drives, it could be because the deceleration time is too short; try prolonging the Dec time. Alternatively, the load might be generating energy or the load inertial might be too big, in which case you should connect a suitable braking kit. Also, consider whether the drive's power is too low and select a drive with bigger power if necessary.
What causes drive overload in Emerson EV2000-4T0075G/0110P DC Drives and how to fix it?
If your Emerson DC Drives show a drive overload, it could be due to several reasons. The Acc/Dec time might be too short, so prolong it. If the DC injection braking current is too big, reduce it or prolong the braking time. An improper V/F curve can also cause this, so adjust the V/F curve or torque boost value. If the motor restarts instantly after stopping, set the starting mode (F2.00) to “start of fly”. Check for low AC supply voltage. Finally, the load might be too heavy, so select a drive with bigger power.
How do I troubleshoot over voltage during acceleration with Emerson DC Drives?
If you're experiencing over voltage during acceleration in your Emerson DC Drives, it might be due to an abnormal AC supply voltage; check the AC supply voltage. Another cause could be a too short Acc/Dec time, so try prolonging the Acc time. Also, if the motor restarts after the drive stops instantly, set F2.00 to the “start on fly” function.
What to do if Emerson EV2000-4T0075G/0110P DC Drives show EEPROM R/W fault?
If your Emerson DC Drives are showing an EEPROM R/W fault due to a R/W fault of control parameters, press STOP/RESET to reset.
What causes the drive's control power supply over voltage in Emerson EV2000-4T0075G/0110P DC Drives?
If your Emerson DC Drives are showing a drive’s control power supply over voltage, it is due to abnormal AC supply voltage. Check the AC supply voltage or seek service.
Why is RS232/RS485 communication failing on my Emerson DC Drives?
If you are experiencing RS232/RS485 communication failure with your Emerson DC Drives, it might be due to a wrong baud rate setting; set the baud rate correctly. It could also be due to a serial port communication error; in this case, press STOP/RESET to reset, or seek service. Improper settings of alarm parameters can also cause this issue; modify FF.02, FF.03 and FL.12. Finally, check the host PC and the wiring to ensure they are working correctly.
What to check if Emerson EV2000-4T0075G/0110P show input phase loss?
If you're experiencing an input phase loss with your Emerson DC Drives, it means that one of the phases R, S, or T cannot be detected. To resolve this, check the wiring and installation, and also check the AC supply voltage.
