Servo Amplifier SD2B

Servo Amplifier SD2B plus

The servo amplifier SD2B plus allows sensorless operation of low-voltage asynchronous and synchronous motors with speeds up to 120,000 rpm, as well as control with TTL encoders.

Due to this motors can be operated speed-controlled and torque-controlled even from speed zero. The safety function "Safe Torque Off" (STO) is integrated as standard in the device to allow low-cost realization of the steadily increasing demands towards machine safety.

The NRTL/CSA certified devices are easily integrated into systems for the US market with no additional approvals needed.

Highlights

  • Master-Slave-Operation

    Function:
    Synchronization of several SD2B plus via TTL encoder inputs and outputs.

    Advantage:
    Autarkic high-precision synchronization of several SD2B plus Servo Amplifier without external control components.

    Benefit:
    Lower system costs.

  • Integrated Logic Voltage Supply

    Function:
    NRTL/CSA certified.

    Advantage:
    asier integration into machines for the North American market.

    Benefit:
    Lower costs, as no additional approvals are necessary.

  • Parameterization via USB

    Function:
    Logic voltage supply via USB interface.

    Advantage:
    Parameterization of SD2B plus without connected voltage supply is possible via the USB interface, which allows pre-configuration of devices outside the machine.

    Benefit:
    Lower system costs.

The Space Marvel

The IP20 housing of SD2B plus convinces with its reduced construction height of only 25 mm. This special compact design allows easy and flexible integration of the device. Besides two TTL encoder inputs and outputs SD2B plus provides five digital inputs and outputs each, analog reference value setting as well as a USB interface for easy parameterization. The serial bus connections CAN and RS232 are integrated as standard and allow realization of all control processes.

Applications

  • High-speed spindles are the key components of a machine tool. Only when operated in an optimal way, the desired machining accuracy, productivity and service life of the whole machine is guaranteed. 

     

    Drilling, Routing

  • For dressing applications, it is essential to keep the spindle temperature low: a temperature increase in the spindle causes a longitudinal growth and therefore a shift of the tool position. 

     

    Dressing

  • Small CAD/CAM routing machines are used, for example, in dental laboratories for jewelry making or engraving works as well as for producing advertising displays. 

     

    Dental CAD/CAM

  • Polygon scanners are based on special optics and operate, for example, sorting machines. Up to now, manufacturers had to install encoders to run these scanners with a high speed stability.
