Check and correct the setting in n003.
·
Input in 2-wire sequence while 3-wire sequence is in effect and vice-versa.
The Inverter will operate in 3-wire sequence according to the RUN, stop, and for-
ward/stop commands if n052 for multi-function input 3 is set to 0. At that time, the
Inverter will not operate if input in 2-wire sequence is ON. On the other hand, the
Inverter in 2-wire sequence will only rotate in the reverse direction if input in 3-wire
sequence is ON.
Check and correct the setting in n052 or change the input method of the RUN com-
mand.
·
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 indica-
tor 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 out-
put 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 termi-
nals is incorrectly wired. Use the Digital Operator and check the setting in multi-func-
tion 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.
