1
Coast to stop and display “AErr”
2
Continue operation by the last frequency command
This parameter determines the behavior when ACI is lost.
When setting to 1, it will display warning message “AErr” on the keypad(optional) in case of
loss of ACI signal and execute the setting. The AC motor drive will stop outputting immediately,
the motor will free run to stop. Please press “RESET” key to clear it.
When setting 0 or 2, it will not display warning message “AErr” on the keypad(optional) in case
of loss of ACI signal and execute the setting. If it is set to 0, the motor will decelerate to 0Hz by
the setting of deceleration time (Pr.01.10/Pr.01.12). If it is set to 2, the motor will continue to
run. For these two settings, the warning message will stop blinking when ACI signal is
recovered. Please press “RESET” key to clear it.
