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 n37 for multi-function input 2 is set to 0. At that time, the In-
verter will not operate if input in 2-wire sequence is ON. On the other hand, the Invert-
er in 2-wire sequence will only rotate in the reverse direction if input in 3-wire se-
quence is ON.
Check and correct the setting in n37 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, press the Mode Key to change the mode of the Inverter,
and restart the Inverter with the green indicator lit.
•
The frequency reference is too low.
If the frequency reference is set below the minimum output frequency set in n14, the
Inverter will not operate.
Raise the frequency reference to at least the minimum output frequency.
•
The Inverter is in local mode.
The Inverter in local mode starts with the RUN command given with the RUN Key
pressed.
Check the LO/RE indicator. If the display is “Lo,” the Inverter is in local mode. Press
the Increment Key and set the Inverter to remote mode with “rE” displayed.
If the above operation is not possible, a multi-function input is set to local/remote
selection. In that case, the mode can be changed with the multi-function input only.
Turn the corresponding input terminal OFF so that the Inverter will be set to remote
mode.
•
The wiring on the Inverter control circuit terminals is incorrect.
The Inverter cannot check input signals if the input wiring on the control circuit termi-
nals is incorrect.
Operate the Digital Operator and check the input terminal status of multi-function
monitor U06.
The NPN or PNP input sequence is selectable. The NPN input sequence is the
default setting.
Refer to 2-2-2 T erminal Block and check that the setting of switch SW7 and wiring are
correct.
