After one cycle of programmable multi-speed (PLC) run is finished, one effective impulse signal is sent with width of
500ms.
16
：
programmable multi-speed stage finished
After the present stage of programmable multi-speed (PLC) is finished, one effective impulse signal is sent with
width of 500ms.
17
：
upper and lower limit of traverse frequency
When traverse frequency function is selected, if the fluctuation range of traverse frequency counted based on
central frequency exceeds upper limit F0.16 or lower limit F0.17, this indicator signal will be sent. As showed in the
following figure.
18
：
current limiting action
This signal is sent when VFD is during current limiting. See FA.06
～
FA.08 for limiting protection setting.
19
：
stall over voltage
This signal is sent when VFD is in action of stall over voltage. See FA.04 for the corresponding protection setting.
20
：
low voltage lock-up
This signal is output when DC bus voltage is lower than the low voltage limit.
