0 : v
≥
0.3 m/s
1 : v < 0.3 m/s
Bit S5 : Desired distance / Speed accepted
DCP3 and DCP4:
0 : During Emergency Stop or Stall Prevention
1 : The speed was accepted by the drive controller
Bit S6 : Mechanical Brake
DCP3 and DCP4:
Corresponds to the mechanical brake relay of the drive controller.
0 : Mechanical brake closed
1 : Mechanical brake open
Bit S7 : Error in last message received
DCP3 and DCP4:
This bit is set if the drive controller has detected a checksum error in the last message from the lift controller and
has therefore ignored it. In this situation, the lift controller repeats the telegram automatically.

The content of the two data bytes depends on the type of transmitted message. Three different kinds of
information can be transmitted:
• Extended status of the drive controller
• 15-bit deceleration distance
• 16-bit deceleration distance

Bit 0 : V
Unlock
Speed for Unlocking Zone
The actual speed is slower than the maximum speed for unlocking zone (v < 0.8 m/s).
0 : The actual speed is faster or equal than the max. speed for unlocking zone (v >= 0.8 m/s)
1 : The actual speed is slower than the max. speed for unlocking zone (v < 0.8 m/s)
Bit 1 : V
Border
Border Speed
The actual speed is slower than the adjustable border speed [d1-30] .
0 : The actual speed is faster or equal than the border speed (v >= v
Border
)
1 : The actual speed is slower than the border speed (v < v

Bit 2 : V
Over
Overspeed
The actual speed is slower than the adjustable overspeed [d1-31] .
0 : The actual speed is faster or equal than the overspeed (v >= v

Bit 3 : Reserved
Currently not supported.
Bit 4 - 8 : Reserved for Weight Detection
Currently not supported.
Bit 9 : Emergency Power: Reduced DC Bus Voltage (Battery Supply/UPS)
The drive controller has reduced voltage (supplied by battery/UPS) during emergency power.
0 : Reduced DC Bus voltage not active
1 : Reduced DC bus voltage active
