Low voltage
⒈
Check whether the input voltage in
normal.
⒉
Check whether there is sudden
change in load.
⒊
Check whether there is any phase
absent.
Overheat of
inverter
⒈
Check whether the fan is in stop-
rotation and whether there is any
foreign matter stuck in the cooling
ns.
⒉
C h e c k w h e t h e r t h e a m b i e n t
temperature is normal.
⒊
Check whether there is enough
ve nt i l at io n s p a ce a nd go o d a i r
convection.
Inveter
overload
150%1 min.
⒈
Check whether the capacity of the
inverter is lower. Otherwise it should
be increasd.
⒉
C h e c k w h e t h e r t h e r e i s a n y
jamming in the mechanical load.
⒊
The setting of V/Fcurve is bad.
Reset it.
Motor
overload
150%1 min.
⒈
Check whether there is any sudden
change in the mechanical load.
⒉
The equipped motor is too small.
⒊
The motor is hot and the insulation
becomes bad.
⒋
Check whether the
voltage has big uctuation.
⒌
Check whether there is any phase
absent.
⒍
The mechanical load is increased.
