Warning
display
Display content Description
Uu
Under voltage
detection
Detected under voltage, the inverter can continue
working after detected
OLP2
Warning of the
inverter’s overload
beforehand
The inverter working current exceeded overload
detection level and maintained a longer time than
the setting of overload detection time. The
inverter would continue working after detected.
OH2
Temperature of the
radiator is high
Temperature of radiator is over OH2 detecting
benchmark, the inverter would continue working
after detected.
AE1
Abnormity analog
signal 1
AI1 analog input beyond range: -0.2~+10.2V
AE2
Abnormity analog
signal 2
AI2 analog input beyond range: -0.2~+10.2V
SF1
Illogical function
code setting
Function of I/O terminals, SS0-2, TT0-1 haven’t
been set completely
SF2
Selected mode
differ from setting
of terminals
Setting operation mode isn’t complied with the
setting of
terminalsX1~X8(S2R4GB~3004GB/35R5PB is
X1~X5)
SF3
Output terminal
selection error
( Only for
35R5GB/37R5PB
and above models)
The inverter has three open collector output, the
output terminals D0, Y1, Y2 are programmable
multi-function terminals. Users can select a part
of control signal and monitor signal according to
needs. When collector output is selected for
direction of programmed operating step or faults,
the content defined for function must be the
same(26 or 27) to make D0, Y1, Y2 be an
available combination
6.3 Motor’s Faults and Corrective Measure
If the motor has one of the following faults, please find the reason and take
corresponding corrective measure. Seek for tech support if the measure does not work.
