4XXX series digital thyristor converters for direct current (DC) motors with independent excitation
The 4XXX series thyristor converters are designed for the precise speed and position control of DC motors with independent excitation for main and servo drives. Their control is realized by modern DSP processors and it enables extensible functional drive possibilities, high reliability and stability of the operating characteristics.
Depending on the functional capabilities, the 4XXX converters are divided into four series:
- 4ХХХ-ХХХ-1Х series - basic series with speed and torque control;
- 4ХХХ-ХХХ-2Х series - with position control from internal reference and with MODBUS;
- 4ХХХ-ХХХ-3Х series - with position control from internal reference, with MODBUS and with a function of active backlash compensation in the mechanics;
- 4ХХХ-ХХХ-4Х series - with position control from internal reference, from external pulse reference (dir/step) and with a function of active backlash compensation in the mechanics.
