* If planning to run the Inverter again, first turn OFF the Run Command and Emergency Stop Command from the control circuit terminal and send the Run

Command.

Modes

This section describes the Inverter's modes and switching between modes.

Inverter Modes

The Inverter's user constants and monitoring functions are organized in groups called modes that make it easier to read and set user constants.The Inverter is equipped with 5 modes.

The 5 modes and their primary functions are shown in the Table 3.3

Drive mode

Mode

Quick programming mode

Table 3.3 Modes

Primary function(s)

The Inverter can be run in this mode.

Use this mode when monitoring values such as frequency references or output current, displaying fault information, or displaying the fault history.

Use this mode to reference and set the minimum user constants to operate the

Inverter (e.g., the operating environment of the Inverter and Digital Operator).

Use this mode to reference and set all user constants.

Advanced programming mode

Verify mode

Autotuning mode*

Use this mode to read/set user constants that have been changed from their factoryset values.

Use this mode when running a motor with unknown motor constants in the vector control method. The motor constants are calculated and set automatically.

This mode can also be used to measure only the motor line-to-line resistance.

* Always perform autotuning with the motor before operating using vector control. Autotuning mode will not be displayed during operation or when an error has occurred. The factory setting of the Inverter is A1-02 = 0 for V/f control.

IMPORTANT

When running the Inverter after using Digital Operator, press the MENU Key to enter the drive mode (DRIVE indicator will flash) and then press the DATA/ENTER Key from the drive mode display to bring up the monitor display (DRIVE indicator will light). Run Commands can't be received from any other display. (Monitor display in the drive mode will appear when the power is turned ON.)

Modes

Drive Mode

Drive mode is the mode in which the Inverter can be operated. The following monitor displays are possible in drive mode: The frequency reference, output frequency, output current, and output voltage, as well as fault information and the fault history.

When b1-01 (Reference selection) is set to 0, the frequency can be changed from the frequency setting display.

Use the Increment, Decrement, and Shift/RESET Keys to change the frequency. The user constant will be written and the monitor display will be returned to when the DATA/ENTER Key is pressed after changing the setting.

Quick Programming Mode

In quick programming mode, the constants required for Inverter trial operation can be monitored and set.

Constants can be changed from the setting displays. Use the Increment, Decrement, and Shift/RESET Keys to change the frequency. The user constant will be written and the monitor display will be returned to when the

DATA/ENTER Key is pressed after changing the setting.

Refer to Chapter 5 User Constants for details on the constants displayed in quick programming mode.

Verify Mode

Verify mode is used to display any constants that have been changed from their default settings in a programming mode or by autotuning. “None” will be displayed if no settings have been changed.

Of the environment mode settings, only A1-02 will be displayed if it has been changed. Other environment modes settings will not be displayed even if they have been changed from their default settings.

Even in verify mode, the same procedures can be used to change settings as are used in the programming modes. Use the Increment, Decrement, and Shift/RESET Keys to change the frequency. The user constant will be written and the monitor display will be returned to when the DATA/ENTER Key is pressed after changing the setting.

Example Operations

An example of key operations is given below for when the following settings have been changed from their default settings: b1-01 (Reference Selection), C1-01 (Acceleration Time 1), E1-01 (Input Voltage Setting), and

E2-01 (Motor Rated Current).

Autotuning Mode

Autotuning automatically tunes and sets the required motor constants when operating in the vector control method. Always perform autotuning before starting operation.

When V/f control has been selected, stationary autotuning for only line-to-line resistance can be selected.

When the motor cannot be disconnected from the load, perform stationary autotuning. Contact your Yaskawa representatives to set motor constants by calculation.

The Inverter's autotuning function automatically determines the motor constants, while a servo system's autotuning function determines the size of a load, so these autotuning functions are fundamentally different.

The factory setting of the Inverter is A1-02 = 0 for V/f control.

Example of Operation

Set the motor output power (in kW), rated voltage, rated current, rated frequency, rated speed, and number of poles specified on the nameplate on the motor and then press the RUN Key. The motor is automatically run and the motor constants measured based on these settings and autotuning will be set.

Always set the above items. Autotuning cannot be started otherwise, e.g., it cannot be started from the motor rated voltage display.

DATA/ENTER Key is pressed after changing the setting.

The following example shows autotuning for open-loop vector control while operating the motor without switching to motor 2.
