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.

N E W S: 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

Definition STO function:
(STO) Safe Torque Off, Stop category 0
in accordance with EN60204-1: Safe torque off of the motors
Definition SBC function:
(SBC) Safe Brake Control.
With an additional safe time delay circuit the function SS1 can be realized.
Definition - SS1 function:
Safe Stop and Safe Drive Interlock (Stop category 1 of EN 60204-1)
Safely monitored stop, controller or drive based, with safe torque off.
Therefore the IndraDrive Cs proves its high quality with drive integrated safety again.
More IndraDrive safety functions
Example SBS function
The SBS functions prevent the movement of verticle axes under load and is world-wide the only drive integrated solution in accordance with PL d category 3 or SIL2.

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.
