Combination Of Retry And Reverse; Slow Obstruction Approach; Wait Mode - Siemens SIDOOR ATD401W System Manual

SIDOOR functions
3.3 Extended functions
While the obstruction reversing system is active, any change in an external drive order (see
Table A-16 DCMD signal (Page 287)) immediately ends all open reversing actions (including
the cancelation of wait mode).
Note
A reverse due to a drive order being changed is part of the basic software, and is not
affected by the reversing on account of an obstruction described here (Open → Close, Close
→ Open).
3.3.8.4

Combination of retry and reverse

The reverse and retry systems can be combined. The combination is subject to the following
rules:
● A reverse is made after executing the configured number of retries. The action is
repeated for the number of configured reverses.
● Parameters p3863 and p3880 have no effect when reversing is activated.
● Wait mode becomes active after the last reverse.
● If the number of retries and reversing operations is set to "0", the "retry" following drive
order has a higher priority than the "reverse" drive order.
3.3.8.5

Slow obstruction approach

The position of the last obstruction in the drive direction is automatically stored in the system.
The speed is automatically reduced to the corresponding creep speed (p3670 or p3666) on
approaching this position. The system calculates a braking ramp so that the reduced speed
is reached at the set distance (parameter p3855 or p3872) from the stored position of the
obstruction. If the obstruction can be overcome, the system adjusts the speed after the same
distance back to the "normal" driving curve.
Slow obstruction approach can be activated or deactivated for each drive direction in
parameter p3850.
3.3.8.6

Wait mode

Wait mode is activated according to the configurations of the overcome obstruction system
and the obstruction reversing system. If the system is in wait mode, this is ended any
external change to a drive order. Wait mode is signaled by the process data signal
"DBLCWAIT" (see "Table A-27 DBLCWAIT signal (Page 293)").
Note
If the parameters p3860 and p3864, or p3877 and p3881 are set to "0", the signal
DBLCWAIT becomes active immediately after an obstruction is detected.
