JRA/S x.230.x.1: Blind motors always travel for the complete travel time during positioning movements

In the default setting, the travel strategy "Disconnect output from power after" is set with the "Total travel time". This strategy is very helpful during commissioning, since the blind actuator never knows exactly where the blind is (due to circuit shutdowns). For this reason, the blind actuator always recalculates its travel time and travels through the entire travel range again and again with each new travel via the object "move blinds/shutter up-down".

Position movements with "height = 100%" are always re-triggered or the travel time is restarted.
Note: Cyclical trigger!!!

When using the shutter control module JSB/S 1.1, the total travel time is not recommended! (position drives)

This means that the relays are triggered every time with this setting and switch on the motor for the complete set travel time.

Positioning drives (height) less than 100% are excluded.

After the commissioning phase, it is therefore advisable to change the setting of the travel strategy, e.g. to "end position + 10%".
