ImpulseDrive
Function description
The ImpulseDrive analysis process detects and evaluates external impulses applied to the door
system (for example, slight force exerted on the door in the opening or closing direction).
In conjunction with the automatic ImpulseDrive system (see section Automatic ImpulseDrive
(Page 81)), it is possible to open a heavy door by pressing lightly on the door handle or door
frame.
When the process detects an external impulse, corresponding status information (see Table
A-30 IMPDRVIncr signal (Page 325) and Table A-31 IMPDRVVelo signal (Page 325)) is generated.
The ImpulseDrive detection properties can be individually parameterized to enable adaption to
different door systems.
Parameter assignment
The detection algorithm consists of a distance and a speed component. The sensitivity levels of
both components can be parameterized separately (p1221 and p1222). A parameterizable lead
time (p1220) is added to the detection algorithm to prevent problems caused by the spring
effects of sealing or rubber lips.
See Table 5-33 Calibration and function parameters (Page 192).
Note
The configuration of the ImpulseDrive detection has a direct effect on the automatic
ImpulseDrive, the automatic AssistedDrive and the automatic AssistedStop system.
Requirements for ImpulseDrive detection
• Parameters are matched to the target system
• Control unit is not in learn run
• Drive command is "deenergize" ("DCMD := 0")
• No obstruction has been detected in the detected direction of motion
Distance-based ImpulseDrive analysis
The analysis is based on the increments of the motor encoder in relation to an internal reference
value. This reference value is always set if within the system state "S4: Z_mode" (see Figure 5-4
Sequential control state graph (Page 163)) the change to the "deenergize" door command has
been made and the lead time (p1220) has expired.
The sensitivity level can be specified in parameter p1221. The higher it is, the higher the number
of increments counted before the signal IMPDRVInc changes to high (active).
Speed-based ImpulseDrive analysis
The analysis is based on the increments of the motor encoder or the actual speed derived from
it. The evaluation only takes place within the system state "S4: Z_Mode" (see Figure 5-4
Sequential control state graph (Page 163)), after the change to the "deenergize" door command
has been made and the lead time (p1220) has expired.
