Cygnus servo drives have integrated motion controllers and other key functions
For compactness, advanced motor drives can integrate motion controllers and other key functions into the servo drive. Still, though, the servo drives need versatile real-time control multiple encoders support, and sufficient power output.
Our Cygnus 2- or 4-axis servo drives have a powerful integrated motion control system and integrated input and output filtering so they need a minimum of external components. They integrate input and output ElectroMagnetic Compatibility (EMC) filters, along with key safety functions like Safe Torque Off (STO) and Safe Brake Control (SBC).
These motor drives can be controlled synchronously across an EtherCAT® network, and work as slave or stand-alone using its internal high-performance controller. The same controller allows you to run any custom control loop made by Matlab®/Simulink®. Cygnus accepts a variety of encoders including incremental (RS422), analog, absolute, SinCos, EnDAT, Hiperface, SSI, BISS-C®, and Hall types. The drives work with any motor type including brushless, brushed, linear, stepper, and voice coil. There are dual and quad motor output versions covering a range from 500 W up to 7 kWPK per axis.
There are two versions with 48 or 400 VDC input voltages and 30 or 10 APK input currents. The Cygnus D3-400/4 (400 VDC input voltage with two motor channels) has an optional matching Quasar B1-400/6 bi-directional power supply with AC-DC rectifier. Quasar increases overall efficiency and saves cost on external brake resistors since it can return the regenerative energy back to the grid with no need to dissipate it.
The drives are fully programmable with our versatile PMP (Prodrive Motion Platform). PMP offers motion applications with powerful and diverse APIs, and real-time control ensures fast and effortless commissioning. There are C++, C#, and Python API versions, and custom real-time code can be generated using Simulink or C++ blocks.
