Setpoint Sum 1 - Eurotherm 590SP Product Manual

SETPOINT SUM 1 allows the summing and scaling of three analog inputs to produce
SPT. SUM OUTPUT.
Note: This block is ignored by the drive unless SYSTEM::
CONFIGURE I/O:: BLOCK DIAGRAM:: SPT SUM 1 DEST is
connected to a nonzero tag. The default connection is to tag 289.
ANALOG I/P 1, terminal A2, is the default input. The default output, SPT. SUM
OUTPUT, connects to SETPOINT 1 in the speed loop.
INPUT 0 and INPUT 1 have individual ratio and divider scalers, and signs. INPUT 1 has an additional deadband
function set by DEADBAND WIDTH. When the input is within the deadband, the output clamps to zero to ignore any
noise. This parameter is useful when digital setpoints are used (for example from a 5703, serial communications, or
the RAISE LOWER function block). The inputs have symmetrical limits set by LIMIT. INPUT 2 has no scaling or
limits.
The output after INPUT 0, INPUT 1, and INPUT 2 are summed is also clamped by LIMIT before producing SPT.
