Data Byte 1
Bit 15 : Mode Identification
The braking distance will only be available if the mode identification is cleared.
16-bit braking distance
The two data bytes are containing the actual 16-bit braking distance. The maximum braking distance is limited to
FFFF (Hex) (65535 mm).
While the lift car is stationary or just starting, the value for the braking distance is clamped at FFFF (Hex). During
acceleration, the value increases from 0. During constant speed, the braking distance remains constant.

Transmitted Information Using Data Information Types
Transmitted Information using Data Information Type '0'
The two data bytes are alternately filled by the braking distance (indicated to the lift controller by bit 15 being '0')
and the Extended Status information (bit 15 being '1'). These values must be handled carefully because each type
of transmitted information is updated every 30 ms only. For DCP3, the braking distance always reads 0.
Bit 15
0
1
Transmitted Information using Data Information Type '1'
This mode is not used in DCP3. In this mode, the two data bytes will be used only to transmit the actual 15-bit
braking distance.
Bit 15
0
If bit 15 = 0, the value is evaluated as 15-bit braking distance.
Transmitted Information using Data Information Type '2'
In this mode, the two data bytes are used only for transmission of the Extended Status of the drive controller.
Bit 15
1
If data shall be evaluated as Extended Status, bit 15 must be set to '1'.
Transmitted Information using Data Information Type '3'
This mode is not used in DCP3. In this mode, the data bytes are exclusively used to transmit the actual 16-bit
braking distance.
16-bit braking distance MSB
Transmitted Information using Data Information Type '4'
In this mode, the data bytes are exclusively used to transmit the Extended Status of the drive controller.
