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 (see Parameter 65 - PROGRAM).
FAILURE TO DO SO MAY RESULT IN DAMAGE TO EQUIPMENT AND/OR
INJURY TO PERSONNEL!

65 PROGRAM (PROGRAM FACTORY DEFAULTS)
This parameter is used to reset the programmable parameters back to the factory default
settings. This parameter has three possible settings:
MAINTAIN Maintain parameter settings as they are.
RESET 60 Resets parameters to factory defaults for 60 Hz base frequency.
RESET 50 Resets parameters to factory defaults for 50 Hz base frequency.
NOTE: This parameter will display RESET 60 or RESET 50 until a change is made to one
or more of the parameter settings. Once a parameter is changed, the display will change to
MAINTAIN.
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 EXT FAULT.
66 HISTORY (CLEAR FAULT HISTORY)
This parameter is used to clear the previous faults in the FAULT HISTORY. 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.
70 PID MODE (PID MODE SELECT)
This parameter activates the PID function, and selects whether the PID control will be direct
or reverse acting. Refer to Section 19.0 - AC400 PID SETPOINT CONTROL. The
following options are available:
OFF Disables the PID function to allow “standard” drive operation.
