Information
All other combinations on the DIP switch are invalid and lead at the latest
on demand of safety function (e.g. validating of safety function) to an error
message and the system changes into safe state.

SBC (Safe Brake Control)
The function SBC is used for safe of controlling a holding brake. A holding
brake, which is active in the unpowered state, is operated and monitored us-
ing two-channel technology. Depending on the pre-selection of the DIP
switch (S-ADR) the SBC will be automatically activated in case of release
parallely with STO1. The function SBC always effects to all brake outputs of
the axis module.
The function SBC is used in conjunction with the functions STO to prevent
the movement of an axis in the torque-free state, e.g. due to gravity.
The axis module supports the safety function ”SBC” (safe brake control), ac-
cording to the requirements of EN 61800-5-2, EN, EN ISO 13849-1 „PL d“
category 3 and EN 61508 / EN 62061 „SIL 2“. You will find the safety-related
characteristics in chapter „Technical Data“. The SBC shutdown takes place
within 3 ms.
