RECOMMENDATION
The disconnection point should − if possible − be set to a value
higher than the determined deceleration distance in order to create
leeway for the optimisation of the speed curve behaviour. .
To achieve distances travelled at speed V0 that are as equal and
short as possible, the disconnection points must be set with an accur-
acy of +/-1 cm.
The disconnection points for speed V2 must be set with an accuracy
of +/-1 mm, depending on the setting of V0 before reaching the flush
landing level.
8.10 Course of a Direct Travel with DCP (Sum-
mary)
With protocols DCP3, the control unit and the inverter serially
exchange only signals that would travel via terminals in case of selec-
tion. The speed curve corresponds to a normal travel as described in
the previous section.
At the protocols DCP4 or CANopen, the control unit cyclically
transmits, besides some control signals, the remaining distance to
the next landing to the inverter, thus enabling the inverter to calculate
an ideal speed curve and make the car approach the landing directly.
