1 to 3 drives, 85-265Vac, up to 15/30A
EtherCAT ® Drive Module, Compact, Powerful
The UDMHP/BA is a state of the art series of EtherCAT drive modules with three built-in universal drives. It addresses the needs of modern machinery for both economical and for high performance, scalable and distributed control for motion centric applications.
The UDMHP/BA operates as an EtherCAT node under any SPiiPlus EtherCAT master Controller including the PC based SPiiPlusSC Soft Controller.
The UDMHP/BA addresses high accuracy demanding applications, while the UDMHP/BA econo version addresses more price sensitive applications.
The UDMHP/BA are complemented by the SPiiPlus NT suite of software tools that minimizes network configuration and drive set up efforts and time to market.
The built-in drives are offered with three current levels: 5/10A, 10/20A and 15/30A ((cont./peak).
The modules are powered by a single or three-phase AC from 24 to 265Vac (rectified internally to generate a Vac x 1.4 motor voltage) and by a separate 24Vdc control supply that keeps all low voltage signals alive during emergency conditions. It supports a wide range of position feedback devices: incremental digital, analog SIN-COS, and absolute encoders.
A standard comprehensive set of powerful algorithms to enhance accuracy, move & settle time, smooth velocity, stability and robustness.
