If the Motor Does Not Operate
Use the following information if the motor does not operate.
The motor does not operate when the RUN Key on the Digital Operator is pressed.
The following causes are possible.
The operation method setting is wrong.
If constant b1-02 (Operation Method Selection) is set to 1 (control circuit terminal), the motor will not operate
when the Run Key is pressed. Either press the LOCAL/REMOTE Key* to switch to Digital Operator opera-
tion or set b1-02 to 0 (Digital Operator).
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 H3-09 (Multi-function Analog Input Terminal A2 Function Selection)
is set to 1 (frequency gain), and if no voltage (current) is input, then
the frequency reference will be zero. Check to be sure that the set value and analog input value are correct.
The motor does not operate when an external operation signal is input.
The following causes are possible.
The Inverter is not in drive mode.
If the Inverter is not in drive mode, it will remain in ready status and will not start. Press the MENU Key make
the DRIVE indicator flash, and enter the drive mode by pressing the DATA/ENTER Key. The DRIVE indica-
tor will light when drive mode is entered.
IMPORTANT
If the Inverter is not in drive mode, it will remain in ready status and will not start. Press the Menu Key to make
the DRIVE indicator flash, and enter the drive mode by pressing the DATA/ENTER Key. The DRIVE indicator
will light when drive mode is entered.
INFO
The LOCAL/REMOTE Key is enabled by setting o2-01 to 1 and disabled by setting o2-01 to 2. It is enabled
when the drive mode is entered.
