N472 Linear Actuator
10.3
Lifetime
The following graph shows the decrease in the step size over the lifetime of the N-472. The
lifetime of the N-472 linear actuator is specified as 1 000 000 000 steps. Over this time, the
typical step size decreases by maximum 30 %.

Operating Time and Duty Cycle
The operating time and duty cycle influence the lifetime of the linear actuator. In order to
prevent overheating and strong wear, the operating time and the duty cycle must not exceed
the values given in the following tables. The limit values depend on the following factors:
Setting of the number of steps per second
Use outside or inside the vacuum
Models that are not suitable for use in a vacuum
Number of steps
