Compact multi-axis servo system with high power density

The new DIAS Drive generation MDD 2000 from Sigmatek combines high performance and flexibility for the control of servo motors in a highly compact design. The modular multi-axis servo system is designed with one, two and three-axis modules in various sizes or power classes and already provides many safety functions in the standard model.

The flexible servo system can be operated as single or three-phase with 230-480V AC. Besides one to three axes, a supply, power filter, brake resistor and DC-Link circuit are also onboard – and that within only 75x240x219 mm in size 1, providing high power density. In size 1, the servo system achieves a performance of 4 kW (3x 5 A rated or 3x 15 A peak current) and in size 2, up to 8 kW (3x 10 A rated or 3x 30 A peak current). The overload factor is up to 300 percent. Controller cycle times of 62.5 µs give the DIAS Drives excellent servo performance.

The combined supply and axis module MDP 2000, with up to three integrated axes, can be a stand-alone solution or installed in the network with any number of MDD 2000 axis modules of both sizes. This makes designing a customised drive concept simple. Thanks to clever connection mechanics, Sigmatek says installation time is reduced. With DCB (DC Connection Block) and BCB (Bus Connection Block), all modules can be quickly connected using stacking technology. This eliminates complex individual wiring for current, DC-Link coupling and real-time Ethernet communication with VARAN bus.

In addition to the safe stop functions Safe Torque Off (STO) and Safe Stop 1 (SS1), the MDD 2000 series includes Safe Operating Stop (SOS), Safe Brake Control (SBC), as well as Safety Limited Speed (SLS) and enables applications up to SIL 3, PL e, Cat. 4.

The digital motor feedback interface Hiperface DSL is a standard feature, which saves wiring and time during the initial start-up. In addition to the single cable solution, various encoder types are supported: resolver, EnDat 2.1, Hiperface, sin/cos, TTL, BiSS-C or Tamagawa.

An integrated autotuning function and predefined motion software components in the extensive library of the engineering platform LASAL shorten the time for creating applications.
