Default value: 1,000 s (seconds)
Setting range: 1 ... 1000 s
The rate time determines the D portion of the controller. Typically, no setting is
required here (= 0), since actuator and valve
react abruptly to a sudden occurrence of an error variable.
Increase Td in case of propensity for oscillation.
Initial value for actuators: 0 s

Actual value source M0756
Default value: I/O interface
Setting values:
The actual process value is defined via an analogue input (AIN 1 or AIN 2) of the
I/O interface.
The actual process value is defined via the fieldbus.
This function requires one of the following equipments within the actuator:
Electronic control unit (non-intrusive version)
Potentiometer
Electronic position transmitter EWG/RWG
With stepping mode, the operating time can be increased for the entire or any
portion of the valve travel.
Stepping mode can be individually activated for the directions OPEN and
CLOSE.
