Function
Output when the feedback value falls below
the lower limit of PID control.
Output when the feedback value rises above
the upper limit of PID control
Output when forward rotation is performed in
PID control.
Used when the commercial power supply-
inverter switchover function is used.
Output to open the brake when the brake
sequence function is selected.
Output at the time of a fan fault.
Output when the heatsink temperature
reaches about 85% of the heatsink overheat
protection providing temperature.
When orientation is valid
Output when the motor is running in forward
direction.
*4
Output when the motor is running in reverse
direction.
*4
Output in the regenerative status under
vector control operation.
Output during pre-exitation or operation under
real sensorless vector control.
Output when the output frequency reduces
below the Pr. 865 setting.
Output when the motor torque rises above
the Pr. 864 value.
Output when the number of droop pulses has
fallen below the setting value.
Output on completion of start-time tuning.
Output when the actual motor speed
(estimated actual speed value) reaches the
Pr. 42 (Pr. 50, Pr.116) setting.
⋅ Output during forward rotation or the
reverse rotation signal is ON.
⋅ Output at deceleration even during forward
rotation or the reverse rotation signal is OFF.
(Does not output during pre-excitation LX is
ON.)
⋅ Output during the orientation command
signal (X22) is ON.
⋅ Switched ON when the servo is ON (LX-
ON) under position control. (Switched OFF
when tne servo is OFF (LX-OFF))
Output when the inverter running and start
commands are on.
Output when the power failure-time
deceleration function is executed.
Output during PID control.
Output during retry processing.
Output when the PID output interruption
function is executed.
Signal is output when the servo is on (LX-ON)
and ready to operate.
This signal turns on during power failure or
under voltage of AC power.
