terminals FU and SE. Otherwise, ” H ” level signal is output.
This signal can
be used to control a mechanical brake or other device. When
it is set, to ” 9999 ” ,
the function is changed and areference indicating that the
inverter is in
” PU operation ” mode is output from termainal FU.
Output frequency detection during reverse operation @ •I
(Terminal FU)
For operation of a hoist or
elevator, for example, operation timing of magnetic
brake can be set differently between forward,
run (up) and reverse, run (down) .
Frequency detection

The initial setting is “ 9999”) where output
frequency is detected at 6 Hz during forward
run and reverse run.
FREQUENCY METER CALIBRATION

Frequency meter
Frequency meter can be calibrated, without
use of calibration potentiometer, by operating
the PU.

A pulse train signal is output from
terminal FM. When a digital counter is
connected to terminal FM, frequency can be
monitored through the digital counter.
fnverter output frequency at 1440Hz of
pulse train signal can be set.
