4.3.8 Software Error Display
When power is turned on, the software in the FLASH memory is checked. If an error is detected, software error
display appears.
When “Software Error” is displayed, the main control functions will not operate, disabling transmission and
connection of adjustment tools. Replace the main control board.

4.3.9 Relief Mode Display
If the main control CPU (PP7) malfunctions due to a drive unit setting error or hardware fault, the adjustment tool
may not be able to connect in the normal way. Especially, if data for tool connection (MAC address, IP address,
subnet mask, gateway address, panel name) is incorrect, the adjustment tool cannot be connected.
In this case, using the rescue mode enables you to connect the adjustment tool to the drive unit and correct and
save the setting values in the relevant file.
The Relief mode can be set by manual selection and automatic selection as follows:
a. Turn the power on while pressing FAULT RESET.
(Manual selection: “999”)
b. The MAC address of the main control board is an error.
(Auto selection: “999”)
c. Interrupt signal of the main control CPU (PP7) has become
an error during normal operation
(Auto selection: “998”)
Three-digit code number display is used. In the cases of “a” and “b” that are switching at startup time, “999” is
displayed. In the case of “c” that is switching during normal operation, “998” is displayed. All of the operation
status LEDs (READY, RUN, and FAULT) blink.

In the rescue mode, the adjustment tool is connected, ignoring the MAC address, IP address, subnet mask, and
gateway address. The panel name is “TM drive.” When you use the rescue mode, be sure to check and correct
these settings.
If the system does not recover even if setting values are corrected, hardware error has probably occurred. Save
the setting values to a file in the rescue mode and replace the main control board.
