Rexroth's IndraDrive Cs ECONOMY is a highly scalable servo drive which achieves PL e and SIL 3 ratings in line with EN 13849-1 and EN 61062 requirements. Certified to the new "safe torque off" safety standards, the drive features an STO facility that prevents inadvertent activation as well as supports safe brake control. The compact converters are targeted at applications ranging from 0.05 to 3.5 kW of continuous power. The drives for input voltage 100 to 230 V AC supplies can be used in single-phase operation. The drives for input voltage 200 to 500 V AC cover performance applications from 400 watts to 3.5 kW of continuous power. The innovative multi-encoder interface supports a large number of feedback devices.
