LUST CDS44.032LC1.1.NF – Compact AC Servo Amplifier | CDS44 Series Platform
Engineering Background
LUST Antriebstechnik (now part of the Bonfiglioli Group) developed the CDS44 series as a high-performance, compact servo amplifier platform engineered for demanding motion-control applications in industrial automation. The CDS44 line is widely deployed across European and Asian OEM machine builders for its robust closed-loop torque, velocity, and position control capabilities.
Product Positioning
The CDS44.032LC1.1.NF is a 3.2 A continuous-output AC servo amplifier designed for single-axis servo systems requiring precise dynamic response, compact DIN-rail or panel mounting, and seamless integration with standard industrial fieldbus architectures. It is the preferred choice for procurement engineers sourcing a verified, drop-in replacement or expansion unit for existing CDS44-based machine platforms.

- Wide motor compatibility – supports LUST and third-party AC servo motors with standard encoder interfaces
- Integrated safety logic – STO (Safe Torque Off) ready per IEC 62061 / EN 13849 (verify per firmware revision)
- Parameterization via PC – LUST DriveManager software for rapid commissioning and diagnostics
- Robust EMC design – CE-marked, built-in EMC filter reduces external BOM cost
System Architecture & Signal Flow
The CDS44.032LC1.1.NF operates as a single-axis servo amplifier within a hierarchical motion architecture:
- Host Controller (PLC / CNC) → issues position/velocity/torque setpoints via CANopen DS402 or analog ±10 V reference
- CDS44 Amplifier → executes real-time current loop (≥ 16 kHz PWM), velocity loop, and position loop
- Servo Motor → receives PWM drive output; encoder feedback closes the loop back to the amplifier
- Safety Channel → STO input disables power stage independently of control logic

Technical FAQ
Q: Is the CDS44.032LC1.1.NF compatible with my existing LUST servo motor?
A: In most cases yes, provided the motor’s encoder type (incremental TTL or resolver) matches the amplifier’s feedback card. Contact us with your motor nameplate data for confirmation.
Q: What does “NF” in the part number signify?
A: “NF” denotes the No Fieldbus option – the unit uses CANopen or analog I/O for setpoint input rather than a dedicated fieldbus card (e.g., PROFIBUS, DeviceNet).
Q: Can I use LUST DriveManager software with this unit?
A: Yes. Connect via the RS-232 service port using a standard null-modem cable. DriveManager is available from the Bonfiglioli/LUST support portal.
Q: What warranty does Konmask provide?
A: A 90-day functional warranty covering power-on operation and stated output current. Physical damage caused by incorrect installation is excluded.
Q: Do you provide a datasheet or wiring diagram?
A: Yes – request via support@konmask.com and we will supply available documentation with your order confirmation.
