SETPOINT SUM 2
Setpoint Sum 2 is a general purpose
summing and ratio block that allows two
scalable inputs and one unscalable input to
be combined.
This block is ignored by the drive unless
SYSTEM::CONFIGURE I/O::BLOCK
DIAGRAM::SETPOINT SUM 2 is connected
to a non-zero tag.
This block may be used for friction
compensations in Current Program Winders
(CPW) and Speed Program Winders (SPW).
INPUT 0 and INPUT 1 can be scaled individually using their respective ratio and divider
parameters. LIMIT sets the symmetrical clamps for INPUT 0, INPUT 1 and the final output.

SPT SUM OUTPUT 451 xxx.xx %
Main output of Setpoint Sum 2.
OUTPUT 0 491 xxx.xx %
(STPT SUM 2 OUT 0)
An additional output provided to gain access to Input 0 channel sub-calculations. The result
of (INPUT 0 x RATIO 0) / DIVIDER 0 clamped to within
r LIMIT.
OUTPUT 1 492 xxx.xx %
(STPT SUM 2 OUT 1)
An additional output provided to gain access to Input 1 channel sub-calculations. The result
of (INPUT 1 x RATIO 1) / DIVIDER 1 clamped to within
r LIMIT.
INPUT 0 444 -300.00 to 300.00 %
Input 0 scaled value. By default this is not connected to any analog input.
INPUT 1 443 -300.00 to 300.00 %
Input 1 scaled value. By default this is connected to Analog Input 1 (A2).
INPUT 2 445 -300.00 to 300.00 %
Input 2 unscaled value. By default this is not connected to any analog input.
RATIO 0 447 -3.0000 to 3.0000
Multiplier term for INPUT 0.
RATIO 1 446 -3.0000 to 3.0000
Multiplier term for INPUT 1
DIVIDER 0 448 -3.0000 to 3.0000
Divider scaling for INPUT 0. Dividing by 0 (zero) results in a zero output.
DIVIDER 1 466 -3.0000 to 3.0000
Divider scaling for INPUT 1. Dividing by 0 (zero) results in a zero output.
LIMIT 449 0.00 to 200.00 %
The Setpoint Sum programmable limit is symmetrical and has the range 0.00% to 200.00%.
The limit is applied both to the intermediate results of the RATIO calculation and the total
output.
