Drive Amplifier SD2S for High-speed Applications

Powerful, flexible and compact – these words describe the drive amplifier SD2S by SIEB & MEYER. Using the available operation modes synchronous and asynchronous motors with speeds up to 480,000 rpm can be driven by SD2S, especially in respect of a low motor heating in high-turning motors with small rotor volume. Depending on the application, the operation can be carried out with or without encoder. For the operation with an encoder SD2S offers the possibility to evaluate the common encoder systems existing on the market. SD2S is connected to the higher-ranking control via analog reference values (+/-10 V), digital I/Os, RS232, USB, CAN bus, EtherCAT or Profibus (via SERVOLINK respectively Anybus adapter).

SD2S offers two drive functions characterized by an easy parameterization and a operation for applications up to 120,000 rpm. For asynchronous motors the drive function V/f-PWM is used. By means of the V/f characteristic curve the user can carry out the graphically aided parameterization of the motor. As using the V/f characteristic curve is an established form of motor parameterization for example in grinding applications, the user can take advantage of the experience gained in this field.

The drive function SVC (Sensorless Vector Control) is provided for synchronous motors. SVC allows 4-quadrant operation of high speed synchronous motors and generators so that SD2S can be used for high speed applications such as turbo blowers or turbines for utilization of process energy.

The flexibility of grinding machines largely depends on the possibility of a fast and simple use of grinding spindles. The feature of saving up to 64 motor parameter sets in the drives enables the variable operation with different motors.

The integrated technology functions for the gap elimination allow an efficient machine operation. This is especially advantageous, if an external acoustic emission evaluation is not possible for technical or financial reasons.
