Technical Specifications
EN 61800-5-1
3.6 EN 61800-5-1
The TP devices conform to EN 61800-5-1 (2008), overvoltage category III. Safe electrical separation ac-
cording to EN 61800 is guaranteed between the power circuit and 24V and Earth.
3.7 EN 61800-3
The interference suppression filter in this device complies to EN 61800-3 C2 under the following condi-
tions.
Guidelines for proper grounding and shielding of the TP must be applied.
Guidelines for proper grounding and shielding of the respective drive hardware manual must be ap-
plied.
Restrictions regarding EMC, stated in the drive hardware manual, are mandatory.
With some setups, a single stage line EMC filter or an insulated transformer between mains and TP
might be required. For good EMC behavior it is important to have a low impedance Earth-connection
running in parallel with the AC-Line connected to the J6. Furthermore, the AC-Line should be routed
apart from motor cables.
3.8 Overvoltage
A system of a motor coupled with a load has a certain amount of energy. This energy is mainly kinetic
when the load is moving or rotating. While stopping these loads, the energy must either be stored or
dissipated. The same applies during moves where gravitational energy or spring energy is involved.
The drives recuperate this energy back to the TP and the bridge voltage rises.
3.8.1 Internal Brake Capability
The following measures are provided device internally to store and dissipate energy. The internal capac-
itors can store a certain amount of energy
