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.
I f 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.
