Warning 0xFE00=205 [M,S]:
This warning occurs when the SELFCHECKING routine #1 is in
progress and the check result has not been determined yet.
This selfchecking routine carries out a voltammeter measure of
the motor resistances between phase V and W (Rvw) and
between phase W and U (Rwu) by injecting a fixed 14.7Adc

motor and three phase power bridge. After the gathered data
have been processed and an unexpected result occurred, this
warning message will turn in an alarm information (see below).
