Compact servo drive - Motor and servo amplifier in one
Overview
The ECOMPACT 23E21 is a decentralized compact servo drive that integrates motor, measuring system and servo amplifier in a single NEMA 23 housing. It is mounted directly on the axis so the drive electronics move out of the cabinet and onto the machine.
This compact design reduces space in the control cabinet, shortens motor cabling and simplifies installation for modular machine concepts. The drive operates on a 24 to 60 VDC supply and delivers up to 1.1 Nm peak torque and 0.72 Nm stall torque at speeds up to 2000 rpm. Within the ECOMPACT 23E family, the 23E21 can be combined with different encoder systems, holding brake options and mechanical adaptations so machine builders can match feedback and torque to their application while keeping the footprint small.
Advantages
- Reduces cabinet size and wiring effort by integrating the servo amplifier on the motor and using short local cabling instead of long motor cables.
- Supports modular machine design because each axis forms a self contained motion module that can be added, removed or repositioned with minimal rewiring.
- On drive intelligence with current, speed and position control, graphical sequence programming and integrated diagnostics can take over low level logic that would otherwise need a small PLC.
- Efficient commissioning and service through ECOSTUDIO engineering software with oscilloscope and diagnostic functions that make tuning and troubleshooting faster.
Where it fits
- Pick and place and handling modules where compact axes and simple wiring are important.
- Focusing, inspection and small positioning tasks in electronics, photonics and test systems that require precise motion in tight spaces.
- Low voltage and mobile platforms supplied from a 24 to 60 VDC bus, such as small transport or assistance systems.
- Retrofit projects where existing NEMA 23 based mechanics should be upgraded from stepper to servo performance without major mechanical changes.
Interfaces
- Control modes for digital current, speed and position control with configurable limits for torque, speed and position.
- Fieldbus connectivity with DS402 profile support via CANopen or EtherCAT for integration into standard controllers.
- Local I/O with 5 digital inputs (2 insulated) and 2 digital outputs (2 insulated) for direct connection of sensors and actuators at the axis.
- Engineering environment via ECOSTUDIO with integrated oscilloscope, parameter handling and diagnostics for commissioning and optimization.
- Series options such as incremental or absolute encoders, holding brake and mechanical adaptations available within the ECOMPACT range to align resolution and safety with the machine concept.
