SERVO AMPLIFIER SD2S

Powerful, flexible, low cost – these words describe the servo 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 PROFIBUS* signals and protocols are processed. Alternatively, a CNC control can be connected via the bus system SERVOLINK 4. The communication via EtherCAT (CoE)** is optinally provided

* Via gateway
** CoE = CAN over EtherCAT

FUNCTION • ADVANTAGE • BENEFIT

SMALL CONSTRUCTION VOLUME

  • Function:   Provides a high nominal/peak current ratio.
     
  • Advantage:  Use of a smaller device in applications with short overload requirements.
     
  • Benefit:  Lower costs and construction volume.

UNIVERSAL MOTOR ENCODER INTERFACE

  • Function: Resolver, encoder / linear scale (TTL or Sin/Cos), EnDat, Hiperface, SSI, Hall sensor, linear Hall sensor, magnetoresistive sensor, NAMUR sensor.
     
  • Advantage: High flexibility in the choice of the motor encoder interface.
     
  • Benefit: Low system costs, free choice of the motor manufacturer.

SAFETY INTEGRATED

  • Function: Safety function STO integrated as standard.
     
  • Advantage: No external components such as power contactors.
     
  • Benefit: Reduction of the system costs.

THE SMART DRIVE AMPLIFIER FOR SERVO APPLICATIONS

UNIVERSAL MOTOR ENCODER INTERFACE

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.

SAFETY INTEGRATED

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.
