Partial opening
Description of function
A second open position can be implemented using the "partial opening" drive function. A
"partial opening" describes an opening movement with a set curve profile up to the partial
opening position.
When partial opening is active, the learned or real door width is replaced with the
parameterized partial opening width. All drive functions are supported in partial opening
mode (e.g. curve profile, force and energy limiting, obstruction detection, etc.). Activating
positioning mode overwrites partial opening mode.
If the drive is in the area between the first and second open positions when partial opening
mode is activated, this is detected as an invalid area. In this area, the controller reduces the
drive's speed automatically. The normal curve profile becomes active again as soon as the
drive has moved out of the invalid area or has exited partial opening mode. The scenario
described is not to be evaluated as a fault or an invalid situation.
The continuous torque in the opening direction is not applied at the virtual end stop of the
second open position. The drive is stopped as long as the open command is present
(winding short-circuited "source voltage brake").
Requirements for partial opening mode
The drive can only switch to partial opening mode if the corresponding drive order with
expansion bit is active and the following conditions are met:
●
The controller is in normal mode
●
The drive is at a stop
Partial opening mode can only be terminated actively (reset of the DCMD expansion bit
"partial") at standstill, but is terminated automatically if the controller switches to initial or
learn run mode.
Connection and parameter assignment
The partial opening width can be configured via the driving parameters or the terminal
module (
Main menu > General setup > Special parameters > Partly open width
).
SIDOOR ATD401W
The "Partial opening" function is connected to "Input 2" of terminal X6. See also Section
Digital input signals (Page 131).
SIDOOR ATD410W/ATD420W/ATD430W
The partial open width is defined via the parameter p1206. See Section Calibration and
function parameters (Page 175).
