Servo & Electric Drives
Servo Drives
Vector-control servo drives from 0.4 to 600 kW.
Field-oriented (vector) AC servo drives that control the speed, torque and position of permanent-magnet servo motors. The line includes general-purpose drives, drives with built-in pressure/flow control for servo-hydraulic injection molding machines and presses (also with direct-drive plasticizing functions), rotary-positioning drives, and high-power systems in which one rectifier feeds several inverters in parallel. Drives accept resolver or absolute-encoder feedback and communicate over RS-485 and CAN.

Ranges across the product family. Exact figures depend on the model.
Options
- Compact drives, 0.4–7.5 kW
- Mid-power drives, 3–360 kW
- High-power systems, 110–600 kW, with separate rectifier and inverter modules; one rectifier can feed many drives in parallel

- Rotary positioning drives, 5.5–90 kW
- Accessories: pressure/flow closed-loop control card, multi-pump flow-combining card, bus motion-control card for synchronised cylinders
Applications
- Servo-hydraulic (energy-saving) injection molding machines
- Hydraulic presses and punch presses
- Wire-drawing machines
- Electric plasticizing (direct-drive screw) systems
- Rotary tables and positioning axes
- Metal forming, CNC machine tools, printing and packaging, lifting and heavy industry
