Impact Protection

Impact protection reduces the risk of mechanical damage from an unbraked, unforeseeable impact in the end position.
If the safety distance of the end positions is crossed by the carriage and payload, the shock absorbers compensate,
in full or in part, for the residual energy. The shock absorbers are only intended to protect a foreseeable impact of the
carriage in the mechanical end position and not for continuous operation. The permissible energy absorption is listed
in the HMR catalog. If there is an overload, the impact protection must be replaced.
The use of end position switches with the safety distance required for the application, as described in section 7.5.1, is
not affected by this.
The IP54 cover must be opened as per section 7.4.1 when retrofitting or replacing the impact protection.
7.6.1 Impact Protection Install
