S700 digital servo drive with SIL2 and SIL3 safety

Growing demands on safety and productivity combined with ease of use, uncompromised reliability and fast time to market are just some of today's challenges facing machine builders and process engineers. With standard safety functions including STO (Safe Torque Off) and optional expansion cards for SIL 2 and SIL 3 that offer 'Safe Stop', 'Safe Limited Speed' and 'Safe Direction', the S700 series digital amplifier increases your machine system availability – making a real contribution to these factors. The high performance S700 features a very fast current control loop combined with a *fast drivebus* that helps to deliver the dynamic speed, position and axis synchronisation performance that is fundamental for real throughput and productivity increases - especially for complex drive tasks. All important feedback systems are supported including Single Cable Feedback SFD3 and Hiperface DSL. Drive options include a wide choice of fieldbus protocols and feedback interfaces, whilst one cable connection and seamless operation across Kollmorgen's extensive range of servo motors allows straightforward installation. Rated current options range from 1.5 A to 72 A, in a wide choice of standard single and three-phase line voltages. The compact S700 is easy to set-up and tune, and may be programmed with a built-in Macro programmer for simple single axis positioning functions or with IEC 61131- 3 Structured Text for more complex tasks. For communication of SIL2 and SIL3 safety functions, Kollmorgen offers Ethernet connectivity based systems such as EtherCAT® that include the appropriate safety-related protocols.
