auto-reset. If this value is exceeded, inverter will wait for trouble shooting.
Fault relay is active during automatic fault resetting fault: when inverter fault auto-reset
function is selected, during the period of resetting, it can be determined through this parameter
setting, whether it is required for the fault relay to be actuated to shield the caused fault alarm,
keeping the equipment continue running.
Interval time setting of fault auto-reset: chose the interval time between fault occurring and
automatic resetting actuated
Important: after the fault is automatically reset, the inverter returns to its status
before fault occurs. In the meanwhile, if fault has not occurred for ten minutes after the
fault is reset, the system will automatically clear the previous times of fault-reset.

The three function codes of Set Length, Actual Length and Unit Pulse Number are mainly
used for fixed-length control.
The length is calculated with pulse signal input by on-off input terminal, and it is required
that the responsive input terminal is set as the length count input terminal. Generally when the
pulse frequency is high, it is required to use HDI1 or HDI2 input.
Actual Length = Length count input pulse number/unit pulse number
When the actual length P8.20 exceeds the set length P8.19, multifunction digital output
terminal “Length Reached” outputs ON signal.

The count value is counted in pulse signal input through the counter input terminal in the
multifunction on-off input terminals.
When the count value reaches the set count value, the on-off output terminal outputs the
signal that the preset count value is reached. The counter is cleared to zero and continue to
count the next coming pulse.
When the count value reaches the assigned count value, the on-off output terminal
outputs the signal that the set count value is reached. The counter continues counting until
“preset count value” is reached. The counter is cleared to zero, and continues to count the next
coming pulse.
The assigned count value P8.23 should not be bigger than the preset count value P8.22.
This function is shown as following figure.
