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.

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.
