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.
No function is assigned in the initial setting. Use
Pr.192 to assign a function to the terminal.
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 monitored output frequency, output current,
and torque.
