ACS850 Firmware error
We are facing a fault in ACS850 drive, Code 316 - DAPS Mismatch.
Error Details: There is a mismatch between JCU control unit firmware and power unit (JINT board) logic version. This error code concerns frames E0, E, G, G1 and G2.
Can anyone pl. let me know how to upgrade the firmware.
Is there any procedure for the same?
What type of cable and software required for this.
Thanks in advance.
to update the firmware of an ACS850 you need to ask the support of your local network of ABB service. You must indicate the serial number of your drive.
Only ABB technician can download from ABB site the new FW version, or one old if you need the reverse procedure.
The procedure is very simple: you need one cable RS232 PC side and RJ 45 drive side. The patch that ABB service use, load one exe file from PC and the new FW file.
During the FW update is recommended do not shut down for any reason the drive.
Another possible cause of the fault may be in the JCU-01 card that may be faulty, I've already been having to replace it for the same problem.
Hope this help you, let us know about the results
