H03 Data Initialization
Initializes the current function code settings to the factory defaults or initializes the
motor constants (parameters).
To change the H03 data, it is necessary to press the
and
keys or the
and
keys simultaneously.
If H03 is set to: Function
0
Disable initialization
(Settings made by the user manually will be retained.)
1 Initialize all function code data to the factory defaults
2
Initialize the P03 data (Rated current of the motor) and inter-
nally used constants to the motor constants determined by P02
data (Motor capacity) and P99 (Motor characteristics), as listed
on the next page.
Initializes P09 data (Slip compensation gain) to 0.0.
-If you do initialization while H03 is set at "1" or "2," H03 will automatically go back to
"0" (factory default) at the completion of initialization.
<Procedure for initializing motor constants>
- To initialize the motor constants, set the related function codes as follows.
1) P02 Motor Parameters:
(Rated capacity)
Set the rated capacity of the motor to be used
in kW.
2) P99 Motor Selection: Select the characteristics of the motor. (Refer
to the descriptions given for P99.)
3) H03 Data Initialization: Initialize the motor constants. (H03 = 2)
4) P03 Motor Parameters:
Rated current):
Set the rated current printed on the nameplate
if the set data differs from the rated current.
- If any value out of the general motor capacity is set for P02, the capacity will be
internally converted to the applicable motor rating (see the table on the next
page).
