Servo Drives MDD 2000 with even more Safety

The SIGMATEK DIAS-Drive 2000 series combines high power density and flexibility for servo motor control in a highly compact design. Now even more safety functions are integrated in the MDD 2000 servo drives.

In addition to the most important Safe Torque Off (STO), Safe Stop 1 (SS1), Safe Operating Stop (SOS), Safe Brake Control (SBC) and Safely Limited Speed (SLS) functions already included, further safety functions are now available: safe speed, acceleration, position and rotating direction functions – all SIL 3, PL e, Cat. 4 and TÜV-certified.

For precisely fitting drive solutions, the flexible servo system can be operated single-phase or three-phase with 230-480 VAC. In addition to one to three axes, supply, line filter, braking resistor and DC link are also on board - and all this on only 75x240x219 mm in size 1. Thus, the highest power density is achieved.

Size 1 offers a capacity of up to 3x 5 A nominal or 3x 15 A peak current, the double-width size 2 up to 3x 10 A nominal or 3x 30 A peak current. The overload factor is up to 300 percent. Very short controller cycle times of 62.5 µs give the DIAS drives excellent servo performance. The modules can be used standalone or in combination with any number of MDD-2000 axis modules of both sizes. They can be connected without tools using baying technology. This eliminates the need for complex individual wiring for power, DC link coupling and real-time Ethernet communication.

The Hiperface DSL© single-cable solution is integrated in the standard, which minimizes the cabling effort.
