Drive Amplifier SD2S for Servo Applications

Powerful, flexible, low cost – these words describe the drive amplifier SD2S by SIEB & MEYER. The compact dimensions allow space-saving design of the switch cabinet. Linear motors, rotary servo motors, high-pole torque motors as well as synchronous/asynchronous tool spindles with or without sensor can be driven by SD2S. For the connection to a higher-ranking control analog reference values (+/-10 V) or pulse-direction values, CAN bus or EtherCAT signals and protocols  are processed. Alternatively, a CNC control can be connected via the bus system SERVOLINK 4. SIEB & MEYER offers a SERVOLINK 4 PCI plug-in board for a PC-based control. The used optical fiber technique ensures a fail-safe connection between the CNC control and the drive amplifiers.

SD2S evaluates all common measuring systems for rotary and linear motors. The drive controls systems with absolute value encoders with EnDat, Hiperface or SSI interface, encoders, magnetoresistive sensors, Hall effect sensors, linear Hall sensors, linear scales with 1Vpp or TTL level as well as resolvers.

The currently effective safety category 4 can be reached by the integrated restart lock. As external protective circuits can be reduced, system costs are minimized.
