◆ DCP3: Lift Controller without Absolute Sensor System
■ Travels at V4 followed by Constant Deceleration Distance SV4
Long Travel at High Lift Speed V4 :
1. Before the travel starts, the speed mode "Fast [bit G7]" (V4) is transmitted.
2. The travel starts with activation of travel command bit B1.
3. After the travel command has been switched off, the drive decelerates to crawl speed within the fixed distance
SV4. The distance is supplied by the motor's incremental encoder. Stop switch bit B2 must be activated not
later than at this point in time.
4. The lift controller positions the lift car with the stop switch bit B2.
5. The lift controller switches the travel contactors off when the drive controller ends the travel at S1 = 0.
