DSVA Some servo alarms and serial pulse coder alarms are
0: not displayed in detail.
1: displayed in detail.
Note1) This parameter is applied in only model C. Some servo alarms and serial
pulse coder alarms are displayed in detail in i-series regardless of this
parameter.
Note2) Alarms No. 448, 449 and 380-386 are displayed regardless of this
parameter.
