Your path to intelligent and economical machine safety

Safety technology


As safe as it gets

Bosch Rexroth offers the universal competence for functional safety with products that conform to all current standards.

The support of machine manufacturers through easy implementation of economic system solutions – in components as well as system solutions including software is given.

Since end of December 2009 the new Machinery Directive 2006/42/EC is valid. This requires a risk analysis for your machine and the calculation of a Performance Level which you can determine simply and quickly with IndraDrive Cs.

IndraDrive Cs equipped with highest safety level

TÜV Rheinland certified on 02.11.2010 the IndraDrive Cs STO/SBC safety function.

IndraDrives fitted with the safety option modules STO and SBC fulfill the highest security-integration-level (SIL) or Performance Level (PL):

  • up to SIL3 according to IEC EN 62061
  • up to PL e category 4 according to EN ISO 13849-1

STO/SBC usages

Applications with human intervention, for example a semiautomatic assembly line which need the highest safety requirements on account of the risk analysis

Functional principle

With dual dynamic sampling outputs, a wiring error in the E-Stop circuit can be uncovered without a seperate detection circuit. Wiring errors which are detected by the IndraDrive Cs activate the function STO.

At the same time, the safety logic of the drive activates the brake of the motor automatically with the SBC function for the safe process interruption until the automatic mode is activated again.

Save costs

In addition to maximum personal protection, the IndraDrive Cs also provides for costs savings, as standard wiring error detection circuits are not required.
