The signal goes to the
L
(conducting) level
if
the
output frequency goes beyond the lrequency set
for the sensing level (the value set for Pr.42).
If
the output lrequency is below this level, the sig-
nal is in the
H
(open) level. This signal
ONOFF
operation can
be
used to control
the
electromag-
netic brake, etc.
If
a value is set for Pr.43, frequency sensing is
possible for reverse rotation operation. In this
case, the value set lor Pr.42 is used only for for-
ward rotation operation. For vertical motion,
where the timing
to
apply the electromagnetic
brake should be changed between the upward
and downward motion, setting lor Pr.43 will
be
el-
fective. The factory-setting
ls
"9999".
in which
setting, the value set for Pr.42 is applied for both
forward and reverse rotatlon operation.
