E.g. keyboard display FF-A（return data 0001）， said when fault occurs the inverter state：
forward command、forward state、accelerating running
I-4-5. CRC checkup sum
Data meaning：data frame CRC checkup sum, using 2 bytes.
Checkup sum ＝ address + function code + data
Enclose：CRC computation program：
unsigned int cal_crc16 (unsigned char *data, unsigned int length)
{
unsigned int i,crc_result=0xffff;
while(length--)
{
crc_result^=*data++;
for(i=0;i<8;i++)
