Speed (c64)
The actuator stem moves to the position determined by the input signal at the selected stroking
speed. There are two different speed levels (NORM and FAST).
The transit time (c66) is calculated from the travel and the stroking speed (c65). The transit time
is the time that the actuator stem needs to move through the adjusted travel. The following ap

Dead band (switching range)
The dead band suppresses slight movements of the stem. The dead band represents the sum
of the positive and negative hysteresis. After the actuator has been stationary, the input sig-
nal must change by at least half of the dead band to cause the actuator to move again.
