Operation
Outputted when an instantaneous power
failure or undervoltage protection operation
occurs.
Outputted while the stall prevention function
works.
Outputted when the output frequency
reaches the frequency set in Pr.42 (Pr.43
during reverse rotation) or higher.
Outputted when the output frequency
reaches the frequency set in Pr.50 or higher.
Outputted when the cumulative electronic
thermal O/L relay value reaches 85% of the
trip level. (The electronic thermal O/L relay
function (E.THT/E.THM) is activated when
the value reaches 100%.)
Outputted when PU operation mode is
selected.
Outputted when the reset process is
completed after powering ON the inverter or
when the inverter is ready to start operation
with the start signal ON or during operation.
Outputted when the output current is higher
than the Pr.150 setting for the time set in
Pr.151 or longer.
Outputted when the output current is lower
than the Pr.152 setting for the time set in
Pr.153 or longer.
Outputted when the input value is lower than
the lower limit set for the PID control
operation.
Outputted when the input value is higher than
the upper limit set for the PID control
operation.
Outputted during forward rotation operation
in the PID control operation.
Used to work the electronic bypass function.
Outputted when a fan fault occurs.
Outputted when the heat sink temperature
rises to 85% of temperature at which the
protective function of the Heatsink overheat
is activated.
Outputted when the motor torque is higher
than the Pr.864 setting.
Outputted when tuning at start-up is
completed.
Outputted during trace operation.
Outputted when the actual motor rotations
per minute (estimate) reaches the setting of
Pr.42 (Pr.50).
The signal is ON while the inverter is running
or while the start command signal is ON.
Outputted when the power-failure
deceleration function is activated.
(The signal output is retained until the
function stops.)
Outputted during the PID control operation.
Outputted when the absolute deviation value
exceeds the limit value.
