•
The Inverter is not in RUN mode.
When the PRGM or LO/RE indicator (red indicator) of the Digital Operator is lit, the Inverter does not
start.
Cancel the RUN command, and by pressing the Mode Key, turn ON the green indicator before
restarting the Inverter.
•
The value of the frequency reference is too low.
The Inverter will have no output if the frequency reference is below the minimum output frequency in
n016.
Set the frequency reference to exceed the minimum output frequency.
•
The Inverter is in local mode.
The RUN command can be given to the Inverter in local mode only with the RUN Key of the Digital
Operator. Check the LO/RE indicator. If “Lo” is displayed, the Inverter is in local mode. Press the
Increment Key so that “rE” will be displayed.
If the above operation is not possible, multi-function input will be set to local/remote selection. In that
case, the mode can be switched only through the corresponding multi-function input terminal. Set
the input terminal to OFF so that the Inverter will be in remote mode.
•
The input wiring of the control circuit terminals of the Inverter is incorrect.
The Inverter cannot check the input signal if the input line of the control circuit terminals is incorrectly
wired. Use the Digital Operator and check the setting in multi-function monitor U-96 for the input
terminal status.
The default setting for Inverter input is to NPN sequence input, which can be changed to PNP
sequence input. Refer to
2-2-1 Terminal Block
and check that the SW1 settings conform with the
actual wiring.
H
The motor does not turn with input through the control terminals. (The
frequency reference is set to zero or different from the set value.)
•
The setting of the frequency reference is incorrect.
The frequency reference through analog input will be ignored if the Digital Operator has been
selected for frequency reference settings. The frequency reference through digital input will be
ignored if the Digital Operator has not been selected.
Check that the set value in n004 for frequency reference selection matches the actual method used.
When using analog input, refer to
2-2-1 Terminal Block
and check that the SW2 settings conform
with the actual input (voltage or current).
•
The Inverter is in local mode.
The frequency reference can be given to the Inverter in local mode only with the FREQUENCY
adjuster or through a key sequence on the Digital Operator.
Check the LO/RE indicator. If “Lo” is displayed, the Inverter is in local mode. Press the Increment
Key so that “rE” will be displayed.
If the above operation is not possible, multi-function input will be set to local/remote selection. In that
case, the mode can be switched only through the corresponding multi-function input terminal. Set
the input terminal to OFF so that the Inverter will be in remote mode.
•
The gain and bias settings of the analog input are incorrect.
Check that the frequency reference gain in n060 and the frequency reference bias in n061 conform
with the actual analog input characteristics.
