H03 Data Initialization

Initializes the current function code settings to the factory defaults or initializes the motor
constants (parameters).
Data for H03 Function Setting procedure
0
Disables initialization
(Settings made by the user manually will be
retained.)
1
Initializes all function code data to the factory
defaults
2
Initializes the P03 data (Rated current of the
motor) and internally 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.
Simultaneous keying of
+ keys changes data in
order of 0, 1, 2, and of
+
keys changes data in the
reverse order.
Pressing the
key will fix
the set data.
- 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).
