188
Communication operation and setting
[Run command]
*1 The signal within parentheses is the initial setting. The description changes depending on the setting of Pr. 180 to Pr. 184, Pr. 187 (input terminal
function selection) (page 101).
*2 The signal within parentheses is the initial setting. Since jog operation/selection of automatic restart after instantaneous power failure/start self-
holding/reset cannot be controlled by the network, bit 8 to bit 11 are invalid in the initial status. When using bit 8 to bit 11, change the signals with
Pr. 185, Pr. 186, Pr. 188, Pr. 189 (input terminal function selection) (page 107). (Reset can be executed with the instruction code HFD.)
[Inverter status monitor]
* The signal within parentheses is the initial setting. The description changes depending on the setting of Pr. 190 to Pr. 196 (output terminal function
selection).
