Detailed instruction of parameters
that of P08.25.
The function is illustrated as below:
S terminal
RO1, RO2
Setting range of P08.25: P08.26–65535
Setting range of P08.26: 0–P08.25
Pre-set running time of the inverter. When the
accumulative running time achieves the set
time, the multi-function digital output
terminals will output the signal of "running
time arrival".
Setting range: 0–65535min
The time of the fault reset: set the fault reset
time by selecting this function. If the reset
time exceeds this set value, the inverter will
stop for the fault and wait to be repaired.
The interval time of the fault reset: The
interval between the time when the fault
occurs and the time when the reset action
occurs.
Setting range of P08.28: 0–10
Setting range of P08.29: 0.1–100.0s
The output frequency of the inverter changes
as the load. And it is mainly used to balance
the power when several inverters drive one
load.
Setting range: 0.00–50.00Hz
When the output frequency exceeds the
corresponding frequency of FDT electrical
level, the multi-function digital output
terminals will output the signal of "frequency
level detect FDT" until the output frequency
decreases to a value lower than (FDT
electrical level—FDT retention detection
value) the corresponding frequency, the
signal is invalid. Below is the waveform
diagram:
The set count
value is reached.
