I have a simple program presently operating on this servo motor... does the job... however... there is no fault handling routine in the program. First instructions of the program are as per manual, and perform a software "enable". When the drive detects a valid faults... the fault is displayed and the program stops. There is an input assigned to the "Fault reset" function which when activated does indeed clear the fault, but the program does not resume. Even a cycling of power does not restore the program to run mode... always comes up in a "0" code, for "No fault, disabled". The "enabled" input (J53 pin 4) is active and cycling it does not have any effect The only way to get the program to restart is to download the program and initiate a "run program" from the interface software. Checked out the manuals but there is very little on error handling.

Would appreciate any suggestions.

Thanks

Have you checked the AUTOSTART parameter? If it is set to 0, your program won't restart after a power failure. You then have to give the RUN command manually.

hope this helps
