Internal Parameters
Parameter Declaration Data Type Description
PV_FAC INPUT REAL PROCESS VARIABLE FACTOR
n The PV_FAC input is multiplied by the "process
value". The input is used to adapt the process vari-
able range.
n Default: 1.0
PV_OFFS INPUT REAL PROCESS VARIABLE OFFSET
n The PV_OFFS input is added to the process vari-
able. The input is used to adapt the process vari-
able range.
n Default: 0.0
n Range of Values: Dependent on the sensors used
DEADB_W INPUT REAL DEAD BAND WIDTH
n The error passes through a dead band. The
DEADB_W input decides the size of the dead
band.
n Default: 0.0
n Range of Values: Dependent on the sensors used
PFAC_SP INPUT REAL PROPORTIONAL FACTOR FOR SETPOINT
CHANGES [0..1 ]
n PFAC_SP specifies the effective P action when
there is a setpoint change. This is set between 0
and 1.
– 1: P action has full effect if the setpoint
changes.
– 0: P action has no effect if the setpoint
changes.
n Default: 1.0
n Range of Values: 0.0 ... 1.0
GAIN INPUT REAL PROPORTIONAL GAIN
n The GAIN input specifies the controller gain. The
direction of control can be reversed by giving GAIN
a negative sign.
n Default: 2.0
n Range of Values: %/phys. unit
TI INPUT REAL RESET TIME [s]
n The TI input (integral time) decides the integral
action response.
n Default: 40.0 s
n Range of Values: ³ 0.0 s
MTR_TM INPUT REAL MOTOR ACTUATING TIME
n The operating time of the valve from limit stop to
limit stop is entered in the MTR_TM parameter.
n Default: 30 s
n Range of Values: ³ CYCLE
