SOFTWARE VERS
This parameter displays the software code and revision number of the control board
software. This information is useful when contacting the factory for programming or
troubleshooting assistance. This is a “view-only” parameter, and cannot be changed.
64
MONITOR MODE
This parameter is used to enable (ON) or disable (OFF) the MONITOR MODE function.
The functionality is explained below:
ON
Pressing the PROG/RUN key will activate the PASSWORD prompt. If
the ENTER key is pressed while the password value reads 0000, the
MONITOR MODE is entered and parameters can be viewed (except
for PASSWORD), but not changed.
OFF
Pressing the PROG/RUN key will activate the PASSWORD prompt.
If the ENTER key is pressed while the password value reads 0000,
it will be treated as in incorrect password and the display will flash
ERROR: INCORRECT, and then return to the PASSWORD prompt
to allow another attempt at entering the correct password.

PROGRAM (PROGRAM FACTORY DEFAULTS)
WARNING!
EXTERNAL FAULT (TB-13D) circuitry may be disabled if parameters
are reset to factory defaults! The drive must be reprogrammed after
a RESET in order to insure proper operation (refer to Parameter
65 - PROGRAM).
FAILURE TO DO SO MAY RESULT IN DAMAGE TO EQUIPMENT
AND/OR INJURY TO PERSONNEL!
This parameter is used to reset the programmable parameters back to the factory
default settings for 60 Hz or 50 Hz systems:
MAINTAIN
Maintain parameter settings as they are.
RESET 60
Resets the parameters back to the factory defaults for 60 Hz base
frequency.
RESET 50
Resets the parameters back to the factory defaults for 50 Hz base
frequency.
NOTE:
When a reset is performed, TB-13D will default to a normally open
EXTERNAL FAULT contact because Parameter 50 - TB13D will be reset
to EXTERN FAULT.
66
CLEAR HISTORY
This parameter is used to clear the previous faults in the FAULT HISTORY (Parameter
99). When set to CLEAR and the ENTER key is pushed, the display will change to
MAINTAIN, and the FAULT HISTORY will display NO FAULT for each of the eight fault
histories.
