not exceed the specified value P027.
Positioning is completed
Positioning is not completed
When output to motor is at or above the set freq.,
even if in accel (C045) or decel (C046) ramps
When output to motor is OFF, or at a level below the
set frequency
When output to motor is at the set frequency, during
accel (C045) and decel (C046).
When output to motor is OFF, or is not at a level of
the set frequency
When output current is more than the set threshold
(C111) for the overload signal
When output current is less than the set threshold for
the deviation signal
When the [O] input value < B070 setting (signal loss
detected)
When no signal loss is detected
When the [OI] input value < B071 setting (signal loss
detected)
When no signal loss is detected
Transitions to ON when the inverter is in RUN Mode
and the PID Process Variable (PV) is less than the
Feedback Low Limit (C053)
Transitions to OFF when the PID Process Variable
(PV) exceeds the PID High Limit (C052), and transitions to OFF when the inverter goes from Run Mode
to Stop Mode
