Data Initialization - Sanken SVCO6 Instruction Manual

F1604

Data initialization

This function initializes function code data to the factory presets or user's initial value.
Not only the factory presets but also the value determined by user (user's initial value) can be fixed as the initial value of
the inverter. And, data initialization can be selected from either the factory presets or user's initial value.
By fixing the user's initial value, the function code data can be initialized to the user's initial value even if it is
overwritten for some reason, allowing for resetting the function code within a minimum range.
Code No. Function Name
F1604 Data initialization
● F1604=1: Initialize to factory presets
Function codes are initialized to factory presets.
● F1604=2: Motor parameters measured by auto tuning are invalid.
Return to the motor's initial value of the parameters measured by auto tuning selected by F5001.
If the motor's initial value can not be stored in the inverter, the parameters measured by auto tuning will be initialized
to factory presets.
Parameters measured by auto tuning: F5009-F5014.
● F1604 = 3, 99: user data related
User data initialization and data confirmation shall be carried out in accordance with the following operation
sequences.
(Sequence 1) Setting the initial value of user data
1. Set the required function code.
2. Confirm the user's initial value with F1604=99.
3. Check that ―
4. ― ‖ keeps flashing while the user's initialization value is being stored. Wait until ―
5. Once ― ‖ has disappeared, the function code data can be initialized to the user's initial value with
F1604=3.
(Sequence 2) Initialization of the user data
1. Set F1604=3 to initialize the data determined by F1604=99.
2. Check that ―
3. ― ‖ keeps flashing while the user's data is being initialized. Wait until ―
4. When ― ‖ disappears, the user's data initialization is completed.
Note 1: In operations where the initial value is used, ―
is used for this purpose.
Note 2: As an exception, F1804 and F1805 can not be initialized.
Note 3: When the user's initial value is not determined, "
