EQ7 Series Instruction Manual - TECO-Westinghouse Motor Company

8.5 Reset EQ7 back to Factory Default
Parameter H03
Data Initialization
H03 initializes the current function code data to the factory defaults or initializes the motor parameters.
To change the H03 data, it is necessary to press the + keys or + keys (simultaneous keying).

• Upon completion of the initialization, the H03 data reverts to "0" (factory default).
• If P02 or A16 data is set to a value other than the nominal applied motor rating, data initialization with H03
internally converts the specified value forcibly to the standard nominal applied motor rating. (Refer to Table B in
Section 4.1 "Function Code Tables.")
• Motor parameters to be initialized are for motors listed below under V/f control. When the base frequency,
rated voltage, and the number of poles are different from those of the listed motors, or when non-standard
motors are used, change the rated current data to that printed on the motor nameplate.

When accessing function code P02 with the keypad, take into account that P02 data automatically
updates data of function codes P03, P06 through P23, P53 through P56, and H46. Also, when accessing
function code A16, data of related function codes for each are automatically updated.
