To set the power limits, you need only send the values you wish to change. If you wish to affect only the
upper fault limit, send a comma (2C) followed by the new upper limit value. To disable the low fault limit send
a less-than symbol (‘<’). To disable the high fault limit send a greater-than symbol (‘>’).
3.9.2 Unused 1 [Temperature Fault Limit] (17 52)
NOTE: This message is NOT APPLICABLE to the amplifiers using this protocol. It is included only to be
compatible with existing code that would expect some response. This message will return a fixed
value (in this case, 3F) that should satisfy existing software.
3.9.3 Unused 2 [Current Stage Fault Limit] (17 53)
NOTE: This message is NOT APPLICABLE to the amplifiers using this protocol. It is included only to be
compatible with existing code that would expect some response. This message will return a fixed
value (in this case, [I
DUMMY
, ] 3F , 3F) that should satisfy existing software.
3.9.4 Unused 3 [Power Supply Voltage Fault Limit(s)] (17 54)
NOTE: This message is NOT APPLICABLE to the amplifiers using this protocol. It is included only to be
compatible with existing code that would expect some response. This message will return a fixed
value (in this case, 3F , 3F) that should satisfy existing software.
3.9.5 Unused 4 [Pout Fault Properties] (17 55)
NOTE: This message is NOT APPLICABLE to the amplifiers using this protocol. It is included only to be
compatible with existing code that would expect some response. This message will return a fixed
value (in this case, “11” or 31 31) that should satisfy existing software.
3.9.6 Parallel Input Functions (17 56)
The functions of the eight inputs on the Parallel I/O module can be read and controlled. The table below lists
the functions available. “Serial I/O Code” is the hexadecimal value of the byte that must be sent in the
message to select a particular input function, or that is returned when reading back the currently set
functions. “Function” is a description of the operation that the input will perform. “Active On” shows the
transition edge ( falling,
;or rising, ) or level (L,H) which will cause the function to be executed. To leave a
function unchanged when setting other functions, send a “?” (3F).
