5.2 Stroke limiter
In versions with the stroke limiter, stroke limiting is set to 90° ex works. This setting can be
changed if required. This allows the turning movement towards working position to be limited
to less than 90°, e.g. 45°.
In versions with the DA function, limiting is possible only towards the open position.
