BH record transmission time can be quite long. A record of 2000 long numbers is
approximately 8000 bytes, which take at least 4 second to transmit over RS-232 at a baud
rate of 19,200. During this time:
ƒ
The user program continues to run normally.
ƒ CAN commands are accepted and processed normally.
ƒ RS-232 commands are accepted and executed normally, although the transmission of the
response to them is deferred until after the BH upload is complete.
Example:
A BH command may return the string:
0008000100013f80000000010000
This string is decomposed to a field as follows:
00
(int) 08 8 bytes per data item in the message
0001
Only one data item in message, after the 20-byte overhead
0001
Record taken every TS
3f800000
To scale, multiply result by 1.0. The floating point IEEE representation of 1.0
is 0x3f800000.
00010000
First data item: 0x10000 = 65536
7.5 Debugging Commands for Database Failures
If the motor cannot start due to a database failure (error EC=54), there is evidently a conflict
of parameters, even though each parameter value may be within the permitted range. In
order to determine what has occurred, type CD to display a complete report of the CPU and
database status, including the parameter that has caused the conflict.
