IS300 Series Servo Drive User Manual Operation and Display

4.5 Password Setting
The servo drive provides user password protection function. When FP-00 is set to non-zero
value, the value is the user password. The password protection becomes valid after exiting
the parameter editing status. When pressing PRG key again, "------" will be displayed, and
common menu cannot be entered until user password is input correctly.
To cancel the password protection function, enter with password and set FP-00 to 0. The
user password protection on the parameters in the short-cut menu is determined by the
status of F7-03 but is invalid for parameter value.
■ Super Password
If you forget the password set in FP-00, please do as follows:
1. Press PRG to display "-----".
2. Press key "SHIFT". The cleartext will be displayed.
3. Record the cleartext and send it to the factory for decryption. If encryption fails within 6
hours or the system is re-powered on during 6 hours, obtain the cleartext again.
4.6 Motor Tuning
If vector control is selected, the motor nameplate parameters must be entered correctly.
The vector control mode is dependent on the motor parameters. To implement better control
performance, correct motor parameters must be obtained.
To perform motor tuning, do as follows:
1. Set the command source (F0-02) to 0 (operation panel).
2. Input the following parameters based on the actually selected motor.
F1-01: Rated motor power
F1-02: Rated motor voltage
F1-03: Rated motor current
F1-04: Rated motor frequency
F1-05: Rated motor rotational sped
3. If the counter EMF of the motor is unknown, please disconnect the motor from the load
and set F1-16 to 2 (dynamic tuning). Then press the key RUN on the operation panel.
The servo drive will automatically calculate the value of the following motor parameters:
F1-11: D-shaft inductance
F1-12: Q-shaft inductance
F1-13: Stator resistance
F1-14: Unit
F1-15: Counter electromotive force
A1-02: Encoder installation angle
