Operation
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.
