Sieb & Meyer (Germany) offers the CAN-capable SD2B drive solution in single board design. It was specially developed for use with high-speed spindles in the low voltage range. The included control technologies allow operating synchronous as well as asynchronous motors without sensors and with speeds up to 120000 rpm.
LOW VOLTAGE SPINDLES ARE OFTEN USED in very compact machine concepts with limited space for electronic components. The single board drive amplifier with dimensions of 142 mm x 110 mm x 55 mm solves this problem. It is designed for direct integration into the electronic unit. All interfaces required for the connection to a higher-ranking control, such as CAN, analog reference signals (±10 V), digital I/Os and EIA-232 are already implemented by default. An additional USB port is optionally available. The 24 VDC to 90 VDC input voltage range allows adaptation to the supply voltage of the machine and to the specific rated voltage of the motor. An external operating unit with display may be connected to simplify operation.
The PC software Drivemaster2 allows configuration and parameter setting of the amplifier. The drive amplifier is adapted to asynchronous motors via the V/f curve, whereas synchronous motors are parametrized by entering the usual motor data sheets. The software allows intuitive parameter setting via graphics and block diagrams. A "parameter wizard" guides the user step-by-step through the system configuration featuring interactive help messages and comments for additional support. Furthermore, an oscilloscope function integrated into the software allows optimization of the motors in the machine via the drive-setup-tool and without the need of additional measuring equipment.
In June 2012, the company celebrated its 50th anniversary. The family-run business works in the field of control technology for PCB drilling and routing machines. Other core technologies are control systems for mechanical engineering and automation engineering, servo amplifiers for various drive types, frequency converters for high-speed applications and feed-in technology for renewable energy sources.
