Parameter

Description

P01 Rev_Acting_Enable

Controls the action of an output

0 = direct action (x-w)

1 = reverse action (w-x)

P02 Proportional_Band

Equivalent to the proportional band value (Xp); NOTE: Do not set this parameter to 0

P03 Integration_Time

If this parameter is set to 0, the integral control is disabled (Tn)

P04 Derivative_Time

If this parameter is set to 0, the derivative control is disabled (Tv)

P05 Output_Minimum

The minimum of the output will be limited to this value. Output minimum must be < Output maximum

P06 Output_Maximum

The maximum of the output will be limited to this value. Output minimum must be < Output maximum. Output maximum must be > Output minimum

P08 Aux_Input_Mode

see Auxiliary input function description;

0 = auxiliary input value is ignored

-1 = for direct-acting low limit or reverse-acting high limi

+1 = for reverse-acting low limit or direct-acting high limit

P10 Prop_Limit

If the control is used as Pi or PiD controls (Tn is > 0) the effect of the P-portion is limited by P10.

If the parameter is set to 0, the proportional control is disabled, only Tn and/ or Tv are active .

Default P10 = 50% limits to 0…100%. P10 = 10% limits to 40...60%.
