Terminal function description
1 changeover contact output that indicates that an inverter's
protective function has been activated and the outputs are
stopped.
Fault: discontinuity across B and C (continuity across A and
C), Normal: continuity across B and C (discontinuity across
A and C)
1 changeover contact output
The output is in LOW state when the inverter output
frequency is equal to or higher than the starting frequency
(initial value: 0.5 Hz). The output is in HIGH state during stop
or DC injection brake operation.
The output is in LOW state when the
output frequency is within the set
frequency range ±10% (initial value). The
output is in HIGH state during
acceleration/deceleration and at a stop.
The output is in LOW state when stall
prevention is activated by the stall
prevention function. The output is in HIGH
state when stall prevention is canceled.
The output is in LOW state when an
instantaneous power failure occurs or
when the undervoltage protection is
activated.
The output is in LOW state when the
inverter output frequency is equal to or
higher than the preset detection
frequency, and is in HIGH state when it is
less than the preset detection frequency.
Common terminal for terminals RUN, SU, OL, IPF, FU
Among several monitor items such as
output frequency, select one to output it
via these terminals. The signal is not
output during an inverter reset.
The size of output signal is proportional to
the magnitude of the corresponding
monitor item.
Use Pr.55, Pr.56, and Pr.866 to set full
scales for the monitoring output
frequency, output current, and torque.
