Rexroth IndraDrive Integrated Safety Technology "Safe Torque Off" (as of MPx-16)
Fig. 8-1: Overview - commissioning steps of the "Safe Torque Off" function
The "Safe Torque Off" and "Safe Brake Control" functions (L4 only) are
always active and cannot be deactivated.
During the booting process, the drive system is in the "STO" and "SBC"
operating states; i.e. the output stage and the brake (if available) have been
switched off via two channels.
After the booting process, the safety functions "Safe Torque Off" and "Safe
Brake Control" are active. When the drive is switched from operating mode to
parameter mode, the functionality of the functions "Safe Torque Off" and
"Safe Brake Control" is maintained, i.e. according to the selection, the
functions "Safe Torque Off" and "Safe Brake Control" become active or not.
The connection and wiring of the "Safe Torque Off" and "Safe Brake Control"
function depends on the option used to make the selection at the drive. The
"Examples of application" chapter shows the different options of selection
and wiring.
The inputs and outputs at the connector X49 of the optional safety
technology module must be wired in accordance with the type of safety unit
(active or passive) and on the wiring type (single-channel or dual-channel,
plus-plus-switching or plus-minus-switching):
