1220.2 Outputting a signal during forward-
or reverse-direction operation
• I want to detect the information of inverter
operating the forward direction and convey to the
system.
• I want to detect the information of inverter
operating the reverse-direction and convey to the
system.
• Assign the output terminal function 008 [FWR]
forward-direction operating signal to one of
[CC-01] to [CC-07] that corresponds to the output
terminal and output the signal.
• You can output the signal only when the inverter is
operating in the forward direction by assigning 008
[FWR] to the output terminal function selection.
• The timing chart is as follows.
Parameter
• [FWR] and [RVR] will not be output during DC
breaking or when the servo is on.
• Assign the output terminal function 009 [RVR]
reverse-direction operating signal to one of
[CC-01] to [CC-07] that corresponds to the output
terminal and output the signal.
• You can output the signal only when the inverter is
operating in the reverse direction by assigning 009
[RVR] to the output terminal function selection.
• The timing chart is as follows.
