Automatic Energy Limitation - Siemens SIDOOR ATD401W System Manual

Automatic energy limitation

Description of function
SIDOOR controllers have a system that automatically limits the kinetic energy in the closing
direction.
Risk of injury due to moving mechanical parts
After the door drive has been commissioned in the complete system, arrange for the forces
and energies to be checked by the service personnel, and adjusted if they exceed their limit
values. Please observe the valid applicable standards and directives for the respective
application, as well as the following guidelines:
• The drive is suited for powered guards in accordance with EN 953:1997+A1:2009
• In the factory state, the force and energy limitation parameters in the opening/closing
• These force and energy parameters can be exceeded for specific applications if an
SIDOOR ATD4xxW controllers include a system that automatically limits the kinetic energy
in the opening and closing directions.
The values for the energy limit are determined via the parameter p1202 (in the closing
direction) or p1203 (in the opening direction) and P1204 (NDG mode). After successfully
completing the learn run, the speed values of the drive curve parameters p3668, p3664 and
p3672 are determined according to the mass and configured energy limit are determined and
overwritten.
As of V1.10: If a value greater than 0 is set for parameter p1202 (Energy limit close), p1203
(Energy limit open) and p1204 (Energy limit NDG), parameters p3664 (Max. speed open),
p3668 (Max. speed close) and p372 (NDG speed) always set to the speed that is calculated
from the configured energy limit and the configured mass:
If the value 0 is set for the energy limit, the automatic energy limit is switched off and any
speed within the parameter limits can be selected.
The automatic energy limitation can be suppressed by setting the corresponding energy
limiting parameter to "0". Suppressed energy limiting means that the respective speed is not
overwritten by the learn run.

direction are 4 J and 75 N. Subject to a safety assessment of the overall system and
with the reversing function activated (automatic reopening of guard) these parameters
can be increased in accordance with the standard up to a maximum of 10 J and 150 N.
