Auxiliary functions
26.2.7. X.TIME – Limiting the control speed
Use this auxiliary function to specify the opening and closing times for the entire stroke and limit the control speeds.
When the X.TUNE function is running, the minimum opening and closing time for the entire stroke is auto-
matically entered for Open and Close. Therefore, movement can be at maximum speed.
Factory setting: values determined at the factory by the X.TUNE
If the control speed is limited, values can be input for Open and Close which are between the minimum values
determined by the X.TUNE and 60 s.
