This example shows how HEALTH WORD, HEALTH STORE, and LAST ALARM are updated.
During operation, the controller trips on P3 PORT ALARM (0x0800), the drive loses three-phase power when an SCR
fuse blows (0x0200) and the motor overheats causing the thermistor to open (0x0010). HEALTH WORD is:
0x0010 = 0x0A10.
