The FINANCIAL — The Siemens Industry Automation Division is supplementing its portfolio of distributed motor starters with a version that features a higher degree of protection for spatially distributed drive applications. The M200D AS-i Basic with an AS interface starts and protects motors up to 5.5 kilowatts.
According to Siemens, the robust M200D AS-i Basic motor starter can be installed outside the control cabinet and close to the motor thanks to its compact design and high degree of protection (IP65). This is particularly advantageous for material handling and conveying where extensive distributed drive applications are the norm. The M200D AS-i Basic is available as a direct or reversing starter for motors and can start them electronically and mechanically. The wide setting range up to 5.5 kilowatts permits flexible use of the starter. The motor starter's electronic overload relay and circuit breaker protect the motor against overload and short-circuit. Moreover, the motor starter offers optional full motor protection through the evaluation of signals from temperature sensors mounted on the motor. With the repair switch, the user can open the circuit breaker and thus interrupt the current in order to repair the motor. Diagnostic data such as the equipment status, asymmetry or overload are passed on to higher-level systems via the AS-i.
Connecting cables as well as the AS-i are connected to the motor starter by means of M12 plug-in connectors. This reduces the amount of wiring during commissioning and facilitates rapid replacement of equipment. As the interfaces of the M200D AS-i Basic have been harmonized with the ET 200 pro distributed I/O system, it can be linked up to ET 200pro motor starters and frequency converters by means of uniform plug-in connectors and cabling. The device can be parameterized locally with the help of four DIP switches, with which important motor starter functions can be specified such as activation of the connector-monitoring function or the evaluation function for temperature-sensor signals. As an option, an integrated operator terminal with jog switch and maintained-contact switches for deactivating the Quick Stop function or for changing the operating mode (direct starter versus reversing starter) are available. The Quick Stop function enables rapid shutdown of the motor irrespective of bus runtimes, thus ensuring locally precise, reproducible stopping of the material being conveyed. Integrated brake controllers with voltages of 230 V/400 V AC or 180 V DC are also available.
