AssistedDrive
Function description
AssistedDrive is an analysis process that detects and analyzes external forces acting on the
door or drive system.
In conjunction with the automatic AssistedDrive system (see Section Automatic
AssistedDrive (Page 70)), a door can be moved with motor assistance without the need for
buttons or sensors.
AssistedDrive signals (see Table 6-89 ASDRV signal (Page 213)) whenever an external
assisting force (force with the same direction vector as that of the door movement) acts on
the door or the drive.
Parameter assignment
The detection properties of AssistedDrive can be individually parameterized, thus enabling
the feature to be adapted to different door systems. The thresholds for the detection of
external opposing forces can be specified for each drive direction with the following
parameters:
● p1231 in the opening direction
● p1232 in the closing direction
The "slow" speed profile is adjusted with both of the following driving parameters:
● p3666 in the opening direction
● p3669 in the closing direction
See Table 6-37 Driving parameters (Page 171).
Note
The configuration of AssistedDrive detection directly affects the automatic AssistedDrive
system.
Prerequisites for AssistedDrive
AssistedDrive detection is only active during the following internal system states:
● Initial mode (closing, closed, opening and open)
● Normal mode (closing, partial closure, closed, opening, partial opening and open)
● Slow drive profile (DCMD – expansion bit "slow", see Table 6-75 DCMD expansion bits
(Page 207))
If the system switches into one of the three system states, the signal ASDrv is always set to
active. The actual threshold analysis of the motor current starts after the parameterized
switch-off delay (p1230) and as soon as the value of the square of the difference between
the setpoint and actual speeds falls below 70 mm/s.
