•
The Inverter is not in operation mode.
If the Inverter is not in drive mode, it will remain in ready status and will not start. Press the Menu Key to
display the operation mode, and enter the drive mode by pressing the Enter Key.
•
The frequency reference is too low.
If the frequency reference is set below the frequency set in E1-09 (minimum output frequency), the
Inverter will not operate. Raise the frequency reference to at least the minimum output frequency.
•
There is a multi-function analog input setting error.
If multi-function analog inputs H3-05 and H3-09 are set to “1” (frequency gain), and if no voltage (cur-
rent) is input, then the frequency reference will be zero. Check to be sure that the set value and analog
input value are correct.
•
Frequency reference 2 is specified with multi-step speed operation, and auxiliary frequency
reference is not input.
If multi-function analog input H3-05 is set to “0” (auxiliary frequency reference), and if multi-step speed
reference is used, the auxiliary frequency reference will be treated as frequency reference 2. Check to
be sure that the set value and analog input value (terminal 16) are correct.
D
The motor does not operate when an external operation signal is input.
•
The operation method selection is wrong.
If parameter b1-02 (run source) is set to “0” (Digital Operator), the motor will not operate when an ex-
ternal operation signal is input. Set b1-02 to “1” (control circuit terminal) and try again. Similarly, the
motor will also not operate if the Local/Remote Key has been pressed to switch to Digital Operator
operation. In that case press the Local/Remote Key* again to return to the original setting.
*
The Local/Remote Key is enabled (set value: 1) or disabled (set value: 2) by means of parame-
ter o2-01. It is enabled when drive mode is entered.
•
A 3-wire sequence is in effect.
The input method for a 3-wire sequence is different than when operating by forward/stop and reverse/
stop (2-wire sequence). When 3-wire sequence is set, the motor will not operate even when an input
terminal suitable for forward/stop and reverse/stop is turned ON. When using a 3-wire sequence, refer
to the timing chart on page 5-16 and input the proper signals. When using a 2-wire sequence, set multi-
function inputs H1-01 through H1-06 to a value other than 0.

The Inverter is not in operation mode.
If the Inverter is not in operation mode, it will remain in ready status and will not start. Press the Menu
Key to display the drive mode, and enter the drive mode by pressing the Enter Key.

•
Frequency reference 2 is specified with multi-step speed operation and auxiliary frequency
reference is not input.
If multi-function analog input H3-05 is set to “0” (auxiliary frequency reference) and if multi-step speed
reference is used, the auxiliary frequency reference will be treated as frequency reference 2. Check to
be sure that the set value and analog input value (terminal 16) are correct.
