Traceback pitch (F-13) to Traceback CH12 selection (F-26):
VF66B (DC motor drive) is equipped with an internal traceback function which can store, read out, and
analyze control data such as current and voltage during protection operations to rapidly restore it.
・
Traceback pitch (F-13)
Set an interval of traceback.
・
Traceback trigger point (F-14)
Set a traceback trigger point.
・
Traceback CH1 to CH12 selection
(F-15 to F-26)
Select whether the each channel of
traceback is used as VF66B (DC motor
drive) internal data or a variable of the
internal PLC function.
* The traceback pitch and traceback point should be
set before traceback data of protection operations
and others is captured.
