An actuator system having an actuator with a rotatable shaft. The shaft may have a first running time to rotate from a first position to a second position in one direction. The shaft may have a second running time to rotate from a first position to a second position in another direction. The first and second running times may be separately adjustable. A motor may be connected through a gear train to the rotatable shaft. A processor may control a rotation of the motor and thus the running times of the shaft. The running times may be adjusted with signals to the processor from a remote controller connected to the processor via a communications bus.
