Automatic Energy Limitation - Siemens SIDOOR ATD4 W Series System Manual

4.2.7

Automatic energy limitation

Function description
SIDOOR control units 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.
Take the standards and directives valid for the respective application as well as the following
specifications into account:
• The drive is suitable for use with power-operated isolating guards in accordance with EN ISO
• In the factory state, the force and energy limitation parameters in the opening/closing
• If an additional protective device is used (e.g. an ESPE or pressure sensitive edge), the force
SIDOOR ATD4xxW control units 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), a value greater than 0 is set, the parameters
p3664 (Maximum speed OPEN), p3668 (Maximum speed CLOSE) and p372 (NDG speed) are
always permanently set to the speed (v) calculated from the set energy limit (E) and the
configured mass (m):
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.

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.
