Rexroth IndraDrive Cs with Safe Torque Off (STO)

Rexroth has enhanced the functionality of its IndraDrive Cs servo line by adding STO (Safe Torque Off) functions which were certified on September 2010 along with SBC (Safe Brake Control).

The IndraDrive Cs compact family of drives is targeted at the performance range between 0.1 kW and 9 kW. Features such as the Multi-Ethernet communications port deliver extensive functionality in a small footprint.

Following certification, the IndraDrive Cs with STO/SBC functionality meets the requirements of Cat 4 PL e as defined in EN ISO 13849-1 and SIL 3 as defined in EN 62061.

When the STO function is activated, the drive immediately cuts off the current which generates the torque and field in the motor. That eliminates the possibility of unintended motion when the machine is stopped. SBC is activated in the drive when the STO function is accessed. SBC activates the motor's holding brake, providing an additional mechanical block to prevent the motor from starting.

These safety functions are available for all performance classes and levels in the IndraDrive Cs family including the most recent “ECONOMY” performance level. This compact, low-cost member of the IndraDrive servo family offers substantial servo functionality for most servo drive applications.
