When the operation continues, setting of the minimum frequency against the running
frequency is valid even during the current input loss.
The multi-speed setting signal is prioritized even during current input loss (operate according
to multi-speed setting even during operation in continuous frequency or during deceleration
stop).
When the multi-speed setting signal is turned OFF due to input current loss condition during
the multi-speed operation, it will perform deceleration stop even if it is set to continue
operation for current input loss.
JOG operation is prioritized even during current input loss (switch to JOB operation even
during operation with continuous frequency or during deceleration stop).
When the JOG signal is turned OFF due to input current loss condition during the JOG
operation, it will perform deceleration stop even if it is set to continue operation for current
input loss.
MRS signal is enabled even during current input loss (output is shut off with MRS signal ON
even during operation with continuous frequency or during deceleration stop).
During operation with remote setting and transferred to operation continuation due to input
current loss, acceleration, deceleration, and clear by the remote setting is invalid. They will
become valid after restoring the current input loss.
When the protective function has operated during the operation continuation due to current
input loss, and retry was a success, operation will continue without clearing the operation
continuation frequency.
During operation with added compensation or override compensation and transferred to
operation continuation due to input current loss, added compensation and override
compensation will become invalid. They will become valid after restoring the current input
loss.
Current input loss is detected with the value before the filter.
Operation continuation before the input loss will use the value after the filter.
PID calculation is stopped during the current input loss. However, PID control will not be
disabled (normal operation).
During the pre-charge, end determination or fault determination by the pre-charge function
will not be performed when the current input loss occurs.
Sleep function is prioritized even during current input loss. When the clearing condition of the
sleep function is met during the current input loss, operation is restored with continuation
frequency.
The power failure stop function is prioritized even if power failure current input loss is
detected.
Set frequency after the power failure stop and re-acceleration is the operation continuation
frequency at the current input loss.
When the E.LCI generation at the time of current input loss is selected, E.LCI will be
generated after the power failure stop.
Traverse operation is performed based on frequency even during the operation continuation
during current input loss.
