Example:
The following code sends an EMCY from a routine in two cases: timeout (error code 1) or
out-of-range (error code 2):
…
if (isTimeOut) // Check if timeout occurred
EMCY(1); // Issue EMCY with error code 1
end
…
if (isOutOfRange) // Check if out of range
EMCY(2); // Issue EMCY with error code 2
end
If a timeout occurs, the SimplIQ drive sends an EMCY with the following data:
Byte Contents Remarks
0 Emergency error code 01
1 FF
2
Error register - 0x80 (manufacturer specific) 80
3 Not used 0
4 Manufacturer-specific error field
(1 for timeout) 01
5 0
6 0
7 0
If an out-of-range occurs, the SimplIQ drive sends an EMCY with the following data:
Byte Contents Remarks
0 Emergency error code 01
1 FF
2
Error register - 0x80 (manufacturer specific) 80
3 Not used 0
4 Manufacturer-specific error field
(2 for out-of-range) 02
5 0
6 0
7 0
Note that the user error code and the emergency error code are formatted in the messages
starting with the least significant bit.
