• On the operation panel, "RD" is displayed during backup, and "WR" is displayed during restoration.
NOTE
• To enable restoration, Pr.434 Network number (CC-Link IE) and Pr.435 Station number (CC-Link IE) must be set.
• Backup is performed for parameters for which parameter copy can be performed.
• For the details of backup/restoration function, refer to the GOT2000 Series User's Manual (Monitor).

Addition of the function in the stop mode
selection at communication error
 Operation selection at a communication error (Pr.502, Pr.779)
• For communication using RS-485 terminals or a communication option, operation at a communication error can be
selected. The operation is active under the Network operation mode.
• Select the stop operation at the retry count excess ( Pr.335 , enabled only when the Mitsubishi inverter protocol is selected)
or at a signal loss detection ( Pr.336, Pr.539 ).

During communication using a communication option, "E.OP1" is displayed.

Under position control, the operation is continued to the target position.

When the communication error is removed during deceleration, the motor re-accelerates.
Under position control, the motor does not re-accelerate even when the communication error is removed during deceleration.
• When a communication error is detected during communication through the RS-485 terminals or communication option, the
alarm (LF) signal is output to an output terminal of the inverter. To use the LF signal, set "98 (positive logic) or 198 (negative
logic)" in any of
Pr.190 to Pr.196 (output terminal function selection) to assign the function to the output terminal. (To
output the LF signal even if communication through RS-485 terminals is not performed for the time set in Pr.336 or longer,
or during communication using a communication option, set "3 or 4" in Pr.502 .)
• The operation during communication can be continued (with the warning indication "CF") even when a communication
line error or a communication option fault occurs.
