INVERTER SETTING

(3) Link start mode

The operation mode at power on and at restoration from instantaneous power failure can be selected. To choose the CC-Link operation mode, set "1" in Pr. 340.

After the link has started, parameter write is enabled with a program. (Refer to page 39 for a parameter write program example.)

Note: For Pr. 79 "operation mode", different inverters have different functions. For full information, refer to the inverter manual.
