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 Band C (discontinuity across A
and C)
1 changeover contact output
Switched to LOW when the inverter output frequency is equal
to or higher than the starting frequency (initial value 0.5 Hz).
Switched to HIGH during stop or DC injection brake operation.
Switched to LOW when the output
frequency is within the set frequency
range 10% (initial value). Switched to
HIGH during acceleration/deceleration
and at a stop.
Switched to LOW when stall prevention
is activated by the stall prevention
function. Switched to HIGH when stall
prevention is canceled.
Switched to LOW when an
instantaneous power failure occurs or
when the undervoltage protection is
activated.
Switched to LOW when the inverter
output frequency is equal to or higher
than the preset detection frequency,
and to HIGH when it is less than the
preset detection frequency.
Common terminal for terminals RUN, SU, OL, IPF, FU
Outputs a selected monitored item
(such as output frequency) among
several monitored items. The signal is
not output during an inverter reset.
The output signal is proportional to the
magnitude of the corresponding
monitoring item.
Use Pr.55, Pr.56, and Pr.866 to set full
scales for the monitored output
frequency, output current, and torque.
