These drive units possess following virtues:
- Wide choice of arrangements on power and developed torque;
- High dynamic responses;
- Possibility of guidance both by means of analogue signal, and by the digital channel;
- The complete absence of drift at guidance by the digital channel;
- Wide choice of adjustments;
- Preliminary treatment of errors and indication of a current state (velocity of gyration, a current of the drive, a developed torque, temperature, etc.).
