Crawl Travel in DCP4

There is no definition of a crawl travel sequence in DCP4. The lift controller chooses one of the described travel
sequences dependent on the remaining distance.
Exception:
• If the remaining distance at start is less than 20 cm, the drive controller limits the maximum speed to crawl
speed.
• The inspection and rescue travels are independent of the DCP3 and DCP4 modes. In this case, the speed is
limited to crawl speed when the lift levels at the end stop.

DCP Fast-Start Function

The 'Fast-Start Function' allows magnetizing the motor already when the doors are closing and holding the lift car
with opened brake in the level position. This function can be used with DCP3 and DCP4. If the 'Fast-Start
Function' is active and the doors are completely closed, the car can immediately start moving without losing time
for magnetizing the motor and opening the brakes.
Note:
Some additional wirings and shaft signals are necessary to meet the requirements of the EN81-1.
