ETEL DSC2P154-421-000 Servo Drive – High Power
The ETEL DSC2P154-421-000 is a high‑power digital servo drive engineered for the most demanding motion control tasks. It belongs to the DSC2 series but features a higher current rating and reinforced thermal design, making it suitable for driving large‑frame linear motors, torque motors, and heavy‑duty rotary axes. This drive provides the power and control necessary for applications requiring high force and continuous operation.
With a peak current capability exceeding 40 Arms and continuous current around 15 Arms, the DSC2P154-421-000 can handle large inertia loads and aggressive acceleration profiles. Its advanced current loop architecture ensures precise torque regulation even at stall, while the built‑in diagnostics monitor temperature, current, and voltage to prevent faults and extend component life.
Key Features
High Continuous and Peak Current: 15 Arms continuous, 45 Arms peak for 1 second.
Reinforced Cooling: Large heatsink and optional fan for high power dissipation.
Flexible Control Modes: Torque, velocity, and position control with smooth transitions.
Advanced Feedback: Supports high‑resolution absolute encoders and sine‑cosine encoders.
Integrated Safety Functions: STO, SS1, and SLS (Safe Limited Speed) for machine protection.
EtherCAT and CANopen: High‑speed network connectivity for synchronized multi‑axis systems.
Technical Specifications
Operating from a DC bus voltage of 300–565 VDC, the drive delivers a continuous output current of 15 Arms and a peak current of 45 Arms (1 s). The switching frequency is adjustable from 8 to 16 kHz, and the power stage uses IGBT technology for high efficiency and ruggedness. The module includes a built‑in braking transistor and supports external resistors. Environmental ratings include operation from 0 to 45 °C ambient, with derating above 40 °C. The drive is housed in a robust metal enclosure with IP20 protection.
