Description
When parameter 40.51 Set 1 trim mode
defines the effect of direct and proportional trim sources in the
final trimming factor.
0.000 = 100% proportional
0.500 = 50% proportional, 50% direct
1.000 = 100% direct
Trim mix.
Defines a multiplier for the trimming factor. This value is
multiplied by the result of parameter
Consequently, the result of the multiplication is used to
multiply the result of parameter
Multiplier for trimming factor.
Selects the reference to be trimmed.
PID setpoint.
PID controller output.
Selects the source that determines whether process PID
parameter set 1 (parameters 40.07...40.56) or set 2 (group
Process PID set 2) is used.
0 = Process PID parameter set 1 in use
1 = Process PID parameter set 2 in use
