Tips/FAQ/Troubleshooting
Exemplar measures to be taken
• 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.
• Check the operation command destination. Check [AA111]
and the terminal function. See "12.5 Select a operation
command." for details.
• 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.
• 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.
• If the operator keypad doesn't show RUN, a shutoff function
or the main power supply may not be turned ON.
• There is another factor for why the motor is not driven. 
