D SERIES Digital servo drives

D SERIES Digital servo drives

The D SERIES digital servo drives family (12IRD, 6ID, 6AXD) are designed to power and control the operation of DC motors both in wound field and in permanent magnets.

In D SERIES digital servo drives, the thyristor bridge for the reinforcement is inserted inside the container for armature currents up to 500A and for larger currents an external bridge to the servo inverter is used; while the field bridge is always inside the converter.

The I/O Connectors, the LCD display, the programming keys and the USB port are mounted on the front, fully accessible to facilitate connections, measurements, adjustments, adaptations and operation diagnostics.

All D SERIES digital servo drives control and regulation circuits are digital and completely isolated from power.

The digital inputs and outputs are static and opto-isolated, the analog inputs are differentials.

Versions

This servo drive is available in three models:

  • 12IRD: it is equipped with a 12 thyristor bridge to feed the armature and works in the 4 quadrants (bidirectional).
  • 6ID: it is equipped with a 6 thyristor bridge to feed the armature and works in the 2 quadrants (unidirectional).
  • 6AXD: it is equipped with a 6 thyristor bridge to feed the armature, it works in 4 quadrants (bidirectional) and is specific for axis control applications in machine tools or in any application where the cancellation of the backlash around zero.

All models can be supplied with a single phase bridge for field control, able to supply motor field with a maximum voltage of 400Vdc and a current of 20A.

A removable memory card contains a copy of all internal servo drive parameters and allows the rapid transfer of all data to a new converter in the event of a replacement, thus minimizing downtime.

Further information

Armature bridge:

  • 12IRD: maximum output voltage: 400 Vdc or 480 Vdc, maximum output current (with internal armature bridge): from 15A to 500A (peak + 33%).
  • 6ID: maximum output voltage: 440 Vdc or 530 Vdc, maximum output current (with internal armature bridge): from 15A to 500A (peak + 33%).
  • 6AXD: maximum output voltage: 220 Vdc or 280 Vdc, maximum output current (with internal armature bridge): from 15A to 90A (peak + 33%).

Field bridge: maximum output voltage: 400Vdc, maximum output current 20A.
