D-102 Programming 590 Series DC Digital Drive
SETPOINT SUM
Use these function blocks to sum and scale
up to three analog inputs to produce the
SPT. SUM outputs.
INPUT 0 and INPUT 1 have individual ratio
and divider scalers, and signs. 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 the SPT. SUM
output.
SETPOINT SUM
Parameter Tag Range
INPUT 0 309, 444 -300.00 TO 300.00 %
(-200.00 to 200.00 % IN SETPOINT
SUM 1)
Input 0 value.
INPUT 1 701, 443 -300.00 TO 300.00 %
(-200.00 to 200.00 % IN SETPOINT
SUM 1)
Input 1 value.
INPUT 2 423, 445 -300.00 to 300.00 %
Input 2 value.
RATIO 1 6, 446 -3.0000 to 3.0000
Multiplier term for INPUT 1.
RATIO 0 208,447 -3.0000 to 3.0000
Multiplier term for INPUT 0.
DIVIDER 1 419,466 -3.0000 to 3.0000
Divider scaling for INPUT 1. Dividing by 0 (zero) results in a zero output.
DIVIDER 0 420, 448 -3.0000 to 3.0000
Divider scaling for INPUT 0. Dividing by 0 (zero) results in a zero output.
SIGN 1 8, 704 NEGATIVE / POSITIVE
Polarity for INPUT 1.
