SD2x | Efficiency – facts and figures Up to 30 % Less Construction Volume Naturally, high-speed motors require high rotating field frequencies. Standard frequency converters generally allow maximum rotating field frequencies of a few hundred hertz which inevitably results in a 2-pole motor design. However, 2-pole motors have significant disadvantages with regard to the construction volume and the power density. Frequency converters of the SD2x product family are specially designed for the use at rotating field frequencies of up to 8,000 Hz and allow motor designs with more poles. The use of a...

Manufacturing frequency converters requires full attention and a high quality awareness of the staff.

08 SD2x | General product features One software for all devices: Firmware and PC software are significant elements for the performance of modern frequency converters and servo amplifiers. Both parts of the software are constantly developed while ensuring highest software stability. This way the SD2x product family already meets the demands of tomorrow. The central PC software drivemaster2 is the core of the complete SD2x product family. The intuitive user interface supports the user in a simple and fast way from parameter setting to diagnosis. • tree-type structure • block diagrams • interactive...

General product features | SD2x 09 Drive Functions With the product family SD2x SIEB & MEYER offers a variety of drive functions allowing optimal operation of synchronous and asynchronous motors with and without speed sensors. The drive function SVC based on pulse-width modulation (PWM) allows operation of synchronous and asynchronous motors up to 2,000 Hz and 120,000 rpm. The user benefits from the best possible motor performance and low motor heating. • vector control from about 5 % of the rated speed • high-dynamic and speed stable Based on the precise EMF measurement the motor is used as...

SD2x | General product features Load Indicator The load indicator is integrated as standard in all devices of series SD2x. The function is used to monitor the torque generating part of the motor current: Once a preset motor load is exceeded the load indicator generates a message. The function is based on a high-precision and dynamic current measurement. Additional expensive measuring sensors as for example acoustic emission sensors may not be required. The load indicator has different modes with adjustable parameters. Operators benefit from the easy-to-use oscilloscope function which can also...

General product features | SD2x Safety Functions The product family SD2x is equipped with TÜV-certified functions. These functions help to meet the steadily growing requirements towards the functional safety of machines. Compared to solutions with external safety components the safety functions of the SD2x product family offer enormous advantages as cost savings and easy machine organization. The safety function Safe Torque Off (STO) ensures to switch motors to torque-free operation and to prevent restart. Using STO a restart lock of category 4 according to EN 13849-1:2008-12, EN 62061:2008-04...

"In the eighties I studied electrical engineering. Measuring techniques with 1 % accuracy were already considered as great and control technique was taught with flat irons and simple direct current motors as examples. Today, we are working with positioning applications in the nanometer range and high-speed applications with speeds up to 600,000 rpm. Making things move and getting best results excite me until today!" Rolf Gerhardt, head of sales drive electronics at SIEB & MEYER AG

The Team Player The drive system SD2 is designed to control synchronous and asynchronous motors with or without a sensor and permits quick and easy adaptation to the individual case of application – whether used with linear motors, rotary motors or motor-driven machining spindles. This universal drive solution allows realization of high-speed applications up to 360,000 rpm (6,000 Hz). Universal motor encoder interfaces and different connection possibilities to a higher-ranking control allow easy adaptation to changing system requirements – nothing will stand in the way of the optimal realization...

Function, advantage, benefit | SD2 15 Function: The SD2 single and double drive amplifiers can be supplied by a common power supply unit. Advantage: The DC voltage coupling allows recovering energy: The energy produced by the braking axes can be used by the driving axes. Depending on the system performance mains supply for up to 12 axis modules can be realized. Benefit: Low wiring and energy costs. Function: SD2 offers a high-precision evaluation of the torque generating current by default. Advantage: The evaluation can be used for tool monitoring. These are for example detection of tool breakage,...
