System Communication Application Dynamics and precision

System

Optimized for the lower power range, the servo drive ServoOne Junior has all the technological features of the ServoOne family. Full function compatibility and handling within the ServoOne family is always guaranteed.

The ServoOne Junior easily combines cost optimization, minimization of size and maximum functionality. The integration of high-speed fieldbus systems and encoder interfaces guarantees persistence and flexibility. Extensive motion control functions allow a wide range of applications.

3 - 8 A Rated current at 1/3 x 230 V AC
2 - 16 A Rated current at 3 x 400 - 480 V AC
Up to 300% overloadable

Communication

Field bus variety

The product range offers the flexible integration into the world of control and automation technology.
ServoOne provides a wide range of different field bus systems.

Real-time Ethernet-based communication interfaces such as:
EtherCAT, Sercos III, PROFINET IRT or PowerLink
Sercos II + III as the established machine tool communication interfaces
Proven field bus interfaces like CANopen based on DS301/DSP402 and PROFIBUS DP-V1 profiles complete the ServoOne field bus portfolio
