Appendix B Para. Fault List Summary
Confirmation times for
inputting open phase
Default protection in case of
inputting open phase for more
than 35 times in a given moment
Confirmation times for
short circuit of braking
resistor
Default protection in case of short
circuit of braking resistor for
more than 10 times in a given
moment
Confirmation times for
SinCos Encoder
disconnection
Default protection in case of
SinCos Encoder disconnection
confirmed for more than twice
Confirmation times for
outputting open phase
Default protection in case of
outputting open phase confirmed
for more than 2 second
Confirmation of
voltage for charging
relay failure
Protection after the three-phase
in-operation input voltage
reduces to 65/1.414 = 46V, 144
failure reported, the charging
relay may be damaged or the grid
voltage is suddenly decreased.
Confirmation
threshold of Encoder
phase CD failure
No 28 failure reported in case
that the D-value of the absolute
position and computing position
of encoder exceed the setting
value.
Protection threshold of
ABZ encoder
disconnection
Protection in case of speed
feedback deviation of
synchronous motor confirmed for
more than the setting value
When F245=1, F246~F255 have the following meanings
Times of Instantaneous over
current of IGBT
0:two ways of I2t
protection,1:only the first way of
I2t protection,2: only the second
way of I2t protection
