Terminal function description
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.
No function is assigned in the initial setting.
The function can be assigned setting Pr.192.
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.
