Dear Sir/Madam,
I
use
FPGA
drive
ad2s1205
for
testing
fault
detection
delay
time
.
When
EXC
,
SIN,
COS ar NC, the
fault
detection
delay
maximum value is
not
125us
, but
800us
;
if
the
EXC
SIN connect resolver
signal
,
COS NC
,
the
fault
detection
delay
maximum
value is
about
24ms
.
I wonder what the main reason for this phenomenon, and how to judge whether the
the
Rotary
transformer
has
broken
?
