Switch OFF inverter power
Reset from the operation panel (Reset at inverter fault)
∗1 Inverter reset can be made any time.
∗2 Reset can be made only when the protective function of the inverter is activated.
REMARKS
• Refer to page 73 for the programming example of an inverter reset.
NOTE
When a communication line error has occurred, reset cannot be made from the network.
Communication continues during inverter reset. (The inverter cannot be controlled for about 1s after release of a
reset command.)
5.4.4

Communication EEPROM write selection (Pr. 342)

Storage device can be changed to RAM only from EEPROM+RAM for the parameter settings written through the CC-
Link communication. Use this function if parameter settings are changed frequently.

write selection
The above parameters can be set when Pr. 160 User group read selection = "0." (Refer to page 197)
When changing the parameter values frequently, set "1" in Pr. 342 to write them to the RAM.
Performing frequent parameter write with "0 (initial value)" (EEPROM write) set will shorten the life of the EEPROM.
REMARKS
• When "1" (write to RAM only) is set in Pr. 342, powering OFF the inverter will erase the changed parameter values. Therefore,
the parameter values available when power is switched ON again are the values stored in EEPROM previously.
