Description
LINEAR : It is electro-magnetic actuator with a strong return spring. This is in principle electromagnet
with proportional characteristic – the bigger is the current to the actuator, the bigger is the angle of the
actuator. Direction of movement of the actuator lever does not depend on polarity of the current. This
type of actuator has position feedback. Typically it is GAC actuators or Woodward 0-200mA, or
PWM.
BRIDGE : typical examples are actuators from Heinzmann.
It is in principle a DC electromotor driving actuator lever. Since it is a motor, it has bipolar integrating
characteristic – as long as the current flows through the actuator, actuator’s lever moves. Direction of
movement of the actuator lever depends on polarity of the current – when the polarity of the current is
reversed, direction of movement of the actuator lever reverses as well. This type of actuator has
always position feedback. Choose this possibility for Heinzmann actuators and connect the position
feedback signal
LINEAR NO FDB : For example it is electro-hydraulic actuator – in principle a small electromagnetic
actuator with hydraulic booster. It has unipolar proportional characteristic – the bigger is the current,
the bigger is the angle of the actuator. Direction of movement of the actuator lever does not depend on
polarity of the current. Actuator is without position feedback.

8.1.7 Act type 2 – predefined for Woodward ITB PWM
There are 4 identical groups of setpoints in ECON-4. They are used to setup the output circuits for particular
types of actuators and tune the actuator position PID loop.
Note: Normally these Actuator type setpoints are predefined from the factory and there is no need to readjust
them. Modify them if you have a non-standard, or non listed actuator only – see List of tested actuators by
ComAp on page 74
Setting is active when Main PID: Actuator type = Act type 2. Setpoint structure see Act type 1 – predefined
for Woodward ITB 0-200 mA on page 69.
