Instruction Manual for AS380 Series Elevator Integrated Drive Controller
Chapter 7 Parameter Table of Integrated Drive Controller
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
When F245=2, F246~F255 have the following meanings
Internal test parameters, do not
modify
0: 5 segment; 1: 7 segment; 2: <
40% rpm 7 segments, > 40% 5
segments
At low speed, the AIO has too
much interference toward outside.
For example, when CAN has a
poor communication signal, the
change to 0 (5 segments) will
have significant effect, and it will
reduce the heat of the drive, but
may cause too much noise
for inverter at low speed.
Internal test parameters, do not
modify
