6 DCP Interface
Start Parameter Message ('I' '7')
Before starting a travel, the lift controller transmits the desired travel distance and the allowed maximum lift
speed to the drive controller. After calculation of the optimal speed, the drive controller answers with the
minimum distance to travel and the required deceleration distance according to the calculated speed.
Start Parameter Message from Lift Controller
Before each travel, the lift controller sends the following message:
STX 1C
V :
max
'1' = Intermediate Speed 1 (V3 in DCP notation)
'2' = Fast Speed (V4 in DCP notation)
Ss1 ... Ss5 :
Desired distance in cm (ASCII coded decimal format)
(Ss1: 10 4 -digit; Ss2: 10 3
Response to Start Parameter Message by Drive Controller
The drive controller responds with the following message.
STX 1C 'I'
f :
typ
Type of travel ('s' = short travel, 'l' = long travel, with l (long), the maximum lift speed is reached; with s (short)
it's not reached).
Sg1 ... Sg5 :
Total distance in cm (ASCII coded decimal format). If Ss > Sg, a long travel (l) is performed.
(Sg1: 10 4 -digit; Sg2: 10 3
Sv1 ... Sv5 :
Deceleration distance in cm (ASCII coded decimal format). The remaining distance can be extended if it is longer
than Sv.

Weight Measurement State of the Car ('I' '8')
Note:
This function is currently not supported by the drive controller.
To improve the drive's starting behavior, optionally, the lift controller can send the percentage value of the car
load weight before starting a travel.
Weight Measurement Message from Lift Controller
Before starting the travel, the lift controller optionally sends the load weight as a percentage of the nominal load.
STX 1C
The function should not be used in conjunction with the Fast-Start function.
L1 ... L3 :
ASCII coded percentage value of the load weight relating to the nominal load in BCD-format. L1: hundreds, L2:
tens, L3: ones
Examples :
0: Car empty, load 0%
25: Load 25%
100: Full load 100%
Response Weight Measurement Message from Drive Controller
The drive controller responds with the following message.
STX
Compatibility to Former Lift- and Drive-Controller Software
To achieve compatibility to former lift- and drive-controller software:
• The drive controller must also accept the starting command of the lift controller without getting the "I8"
message before.
