Danfoss Error 1027 !new! -

Danfoss Error 1027 is a critical internal communication fault that typically occurs within the VLT series frequency converters (such as the FC 102, FC 202, and FC 302). It indicates that the control card is unable to communicate with the power card or that an internal CAN telegram cannot be sent. What Causes Error 1027?

remains after a hard reset, it usually indicates a permanent internal component failure. In this case, you should contact a Danfoss Service Partner for repair or replacement. parameter settings danfoss error 1027

The causes of Danfoss Error 1027 can vary depending on the specific product and system configuration. However, based on common issues reported by users and Danfoss support teams, some possible causes of Error 1027 include: Check Parameter 8-04 (Control Word Timeout Time): This

Q2: Does Error 1027 damage the drive?
No. It is a protective response. However, repeated stopping/starting of the load (pump, fan, conveyor) can cause mechanical wear.

Step 2: Verify Configuration

• Check Parameter 8-04 (Control Word Timeout Time): This is usually set in milliseconds. Compare this value to the PLC scan time. As a rule of thumb, set the timeout to at least 3-4 times the expected scan rate of the master system.
• Check Parameter 8-01 to 8-03: Ensure the protocol and address settings match the control system requirements.

The key takeaways for any technician or engineer:

Manual Clear – Fieldbus Command

Send a control word bit 07 (Reset trip) via explicit message or from the PLC. Example for Profibus: Control word = 0x0080.
