Function
Output when the output power is lower than the
Zero current detection Pr. 152 setting for longer than the time set in Pr.
153.
Output when the feedback value falls below the
PID lower limit
lower limit of PID control.
Output when the feedback value rises above
PID upper limit
the upper limit of PID control
PID forward/reverse Output when forward rotation is performed in
rotation output PID control.
Electronic bypass MC1
Used when the commercial power supply-
Electronic bypass MC2
inverter switchover function is used.
Electronic bypass MC3
Brake opening
Output to open the brake when the brake
sequence function is selected.
request
Fan fault output Output at the time of a fan fault.
Output when the heatsink temperature reaches
Heatsink overheat
about 85% of the heatsink overheat protection

Output during pre-excitation or operation under
Operation ready 2
Real sensorless vector control.
Output when the output frequency drops below
Low speed output
the Pr. 865 setting.
Output when the motor torque rises above the
Torque detection
Pr. 864 value.
In-position (for FR- Output when the number of droop pulses has
A7AP/FR-A7AL) fallen below the setting value.
*3
Start time tuning
Output on completion of start-time tuning.

Speed detection
Output when the actual motor speed (estimated
Second speed
actual speed value) reaches the Pr. 42 (Pr. 50,
detection
Pr.116) setting.
Third speed detection
⋅ 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
the servo is OFF (LX-OFF))
Inverter running and Output when the inverter is running and start
start command is on command is ON.
During deceleration at Output when the power failure-time deceleration
