S4: Operation
command
destination or
operation
command is
wrong.
• If the LED for RUN on the operator keypad is lit or the
operation display appears, the operation command has
been entered normally. There is another factor for why the
motor is not driven.

Return to S3.
• Even though the operation
command is entered, the motor
does not drive.
• Confirm that “oFW” or “oRV” is shown on the operator
keypad. If it is not shown, then confirm that the operation
command selection [AA111] is set to 02 RUN key on
operator keypad. If it is shown, the terminal function needs
to be checked.
• Check the operation command destination. Check [AA111]
and the terminal function. See “12.5 Select a operation
command.” for details.
• The operation command
destination and the operation
command input are not the
same.
• There is a cause other than the
operation command.
• If the operator keypad doesn’t show RUN, a shutoff function
or the main power supply may not be turned ON.


Return to S3.
• You want to make operation
from the operator keypad but
had made the different setting.
• Set the operation command selection [AA111] to 00 [FW/RV]
terminal. If RUN is not shown when the [FW] terminal is
turned ON, other terminal functions need to be checked.
• You want to make operation
from the [FW] terminal but had
made the different setting.
