
The signal within parentheses ( ) is the initial status. The description changes depending on the setting of Pr.180 to Pr.189 (Input
terminal function selection).

The inverter run enable signal is in the initial status for the separated converter type.

JOG operation/automatic restart after instantaneous power failure/start self-holding selection/reset cannot be controlled over a network,
so in the initial status bit8 to bit11 are invalid. To use bit8 to bit11, change the signal by Pr.185, Pr.186, Pr.188, or Pr.189 (Input terminal
function selection). (A reset can be executed by the instruction code HFD.)
