1 0 .1 Report Ge nera t or
Before contacting Technical Support , creat e a report of application set tings by
m eans of the Report Generat or in ServoStudio. The inform ation cont ained in the
report files will enable Technical Support to troubleshoot your problem and
provide assist ance.
In general, it is strongly recom mended that you create a report whenever you
com plete configuration of your application, even when the system is functioning
properly.
The Report Gener at or option can be accessed in ServoStudio in two locations:
Aut otuning wizard (final st ep)
Backup & Restore screen
1 0 .2 Fault s a nd W a r nings
I f t he CDHD is connected to a host computer via a serial connection, it
communicates fault codes to the com puter by means of a text message. This
message is saved in a fault history log (FLTHIST) in the drive’s non-volatile
mem ory, so that the fault history is not lost when power is removed from the
drive.
W ar nings are not considered faults and do not disable operation. The
system autom atically clears the warning state when the condition that
generated the warning no longer exists.
Fa u lt s occur when settings or condit ions m ay cause improper operation of
the drive/ motor and/ or equipment damage. Faults automatically disable the
drive, and a fault status is indicated on the drive’s display and in the
software interface.
The drive fault status is generally latched, and the drive cannot be enabled
until the fault status is explicitly cleared. Only if the fault condition no longer
exists can the fault status be cleared. It is done by either of the following:
Toggling the drive enable. This is done either by executing a drive
disable com m and (K) followed by the enabled (EN) com m and or by
toggling the Remote Enable line (REMOTE).
I n some systems, a specific drive input is defined as Alarm Clear. I n this
case, toggling the input will clear the fault.
When the fault condit ion no longer exists, the drive is reenabled.
Some faults are referred t o as fa t a l fault s since they disable alm ost all
drive functions (including com munications) and prevent the drive from being
enabled. This condition is typical of faults due to internal failures, such as a
watchdog event or a failure of an int ernal power source. Fatal fault s require
intervention by Technical Support .
