Drive Control & Communication
NOTE 4 - AC Tech Register #100, Parameter 50 - Fault History
When parameter #100 is read, the number of registers must be 4. The drive will send 8
bytes of data back to the MASTER. It does not mean read function reads parameter #100,
#101, #102, and #103. This is a special case to handle the data string. Number in every
byte represents fault in fault history. Latest fault is in the first data byte, oldest fault is in
the last data byte. Refer to table 17 for clarification.
