Description
[2nd V/F selection] is used to specify a particular V/F pattern.
The upper pattern
and the lower pattern
specified by [2nd V/F base frequency] and [2nd V/F boost], as well as the
ordinary V/F pattern can be selected.

Note) Enabled when [
Torque control] is set to “manual boost” only.
To avoid mechanical resonance, you
can specify a range where frequency
setting is disabled, or [

specified by [

•
During acceleration/deceleration, frequency output is enabled even in
the jump range.
•
If jump frequency ranges are overlapped with each other, the entire
overlapped range is regarded as the jump range.
