7.20 ANALOG INPUT WIRE-BREAK DETECTION (GROUP F4.3)
On condition that break detection function of analog input is valid, when the value of AI1, AI2 and AI3 analog
input is within the range of detection threshold level, when the frequency inverter passes the action of break
detection delay, conduct corresponding action according to the selected setting after the wire-break action.
F4.3.39 Action selection after AI1 wire-break Setting range: 0~4 Factory default: 0
F4.3.43 Action selection after AI2 wire-break Setting range: 0~4 Factory default: 0
F4.3.48 Action selection after AI3 wire-break Setting range: 0~4 Factory default: 0
Define corresponding actions after frequency inverter detects analog input wire-breakage.
0: No action (for non-stop alarm)
When detecting analog input wire-break, if the frequency inverter operates normally, it only reports
aL.036-aL.038 warning signal. If the wire-break fault is cleared, the warning signal can be cleared
automatically.
1: Forcedly set to the minimum
When detecting analog input wire-break, if the frequency inverter operates normally, it reports aL.036-aL.038
warning signal. Meanwhile, forcedly set the analog input signal to the minimum of analog input. If the wire-
break fault is cleared, the warning signal can be cleared automatically, meanwhile, the analog input signal
recovers to input value.
2: Forcedly set to the maximum
When detecting analog input wire-break, if the frequency inverter operates normally, it reports aL.036-aL.038
warning signal. Meanwhile, forcedly set the analog input signal to the maximum of analog input. If the wire-
break fault is cleared, the warning signal can be cleared automatically, meanwhile, the analog input signal
recovers to input value.
3: Forcedly set to the default value
When detecting analog input wire-break, if the frequency inverter operates normally, it reports aL.036-aL.038
warning signal. Meanwhile, forcedly set the analog input signal to the default input value of analog input. If
the wire-break fault is cleared, the warning signal can be cleared automatically, meanwhile, the analog input
signal recovers to input value.
4: Inverter forced trip stop
When detecting analog input wire-break, it reports aL.036 - aL.038 fault signal and lock output, and load
motor freely sliding down. If the wire-break fault is cleared, fault signal shall be cleared with hand-reset.
7.21 HOPPING FREQUENCY (GROUP F5.0)
Hopping frequency function makes the output frequency of frequency inverter to avoid the mechanical
resonant frequency point of machine loaded.
Setting frequency of frequency inverter can operate with hopping frequency near some frequency point as
the method in the figure below, with 3 hopping ranges defined at most.
After hopping frequency parameters are set, even the setting frequency of frequency inverter is within the
mechanical resonant frequency band of driving system; Output frequency of frequency inverter will still adjust
out of the mechanical resonant band, operating with lower limiting value of the hopping range of this hopping
frequency.
