Sheet 26 of 39 Document 12245 Rev. I
The following table lists the codes that are returned in response to the 16 59 message. They represent every
fault condition that should be detected by the amplifier. The table also lists the corresponding bit flags
returned by the Get Faults message (08).
An optional one-byte parameter may be sent with this message, called B
ACTIVE_INFO
. If this parameter is
present, and equal to 31, the high bit of each of the following codes will be set if the fault condition is still
active.
