Additional Notes on Command and Status Bits
The following notes apply to DCP3 and DCP4.
Command Bit B0 : Drive Controller Enable
Drive controller enable bit B0 must be set whenever the drive shall run.
Drive controller enable bit B0 must be switched off by the lift controller if the safety circuit is interrupted. This is
usual when terminating inspection travels. In this case, the drive coasts to stop.
Command Bit B4 : Direction
The travel direction must be available throughout the entire travel. The drive decelerates immediately if the setting
changes during the travel, but without the drive controller switching to fault.
Status Bit S0 : Drive Controller Ready
The lift controller only starts a new travel if the drive controller ready bit S0 is set. After power on, bit S0 is held
active for 4 seconds in order to give the lift controller the opportunity to send an I6=
’
U
’
telegram to activate
reduced undervoltage levels in the drive.
Status Bit S1 : Travel-Active Bit
During normal operation, the lift controller switches the motor contactors ON while S1 = '1'. In case of a regular
halt, the drive controller should not set S1 from '1' to '0' before S6 is set to '0', and the lift controller has had time
to close the mechanical brake.
Status Bit S2 : Alarm Active
If re-starting is performed although this bit is set, an error message is sent to the drive controller (DOE1, DCP
Operation Error 1).
The lift controller only starts a new travel if the alarm active bit S2 is reset. If S2 is activated during the travel, the
lift controller should no longer extend the remaining distance.
Status Bit S6 : Mechanical Brake
In case of a regular start, the drive controller should set S6 from '0' to '1' after the Brake Open Delay Time S1-06.
In case of a regular halt, the drive controller should set S6 from '1' to '0' when it has stopped completely. In this
situation, the drive controller should hold the torque for about 100 ms (S1-07 = 100 ms), so that the lift controller
can close the mechanical brake without coasting of the drive.
Status Bit S3 : Fault Active
When general fault bit S3 is activated, drive controller enable bit B0 has to be reset. The lift controller must not
start a new travel until fault active bit S3 has been reset. The stopping method is according to b1-03.

Inspection Travel
These travels are common for DCP3 and DCP4.
Inspection Travel with VI :
1. The speed mode "Inspection [bit G4]" (VI) is transmitted before the travel starts.
2. The travel starts with activation of travel command bit B1 and stop switch bit B2.
3. When the lift arrives at one of the end-stops, the lift controller switches off travel command bit B1 in order to
start its deceleration ramp. If the stop switch bit B2 is still active, the drive continues to travel at crawl speed
(V0).
4. Releasing the inspection button generally opens the safety circuit. That is why an electrical stop is not
possible. When the inspection function is deactivated, the lift controller must switch off drive controller
enable bit B0.
5. When a stop command is received during leveling speed, the drive should use C1-02 [Ramp to Stop] as for
nominal travel.
