Description
The ARS 2000 series represents the new generation of highly dynamic digital servo controllers for three-phase synchronous motors. As the successor of the existing ARS series the philosophy of flexibility and multi-functionality has been continued. The universal encoder interface for a number of angle encoders of well-known manufacturers and the CAN interface are just a few of the outstanding features.
Due to one additional external incremental encoder input and output each, the controllers are suitable for synchronization with variable gear ratios or simple connection to a PLC. Automatic identification functions facilitate and accelerate first commissioning. The servo controllers for control cabinet installation are designed for a rated power of approximately 2500 W for single-phase supply and integrate a Power Factor Correction. The devices thus fulfill the requirements of EN 61000-3-2 regarding current harmonics and achieve a better utilization of the motors and more stable intermediate circuit voltage.
Universal encoder interface
Integrated universal encoder evaluation for the following feedback sensors :
- Resolver, high control quality due to extremely good sensor technology

- High-resolution Heidenhain incremental encoders, absolute encoders with EnDat
Extension and fieldbus modules
- EA88 I/O extension module
- PROFIBUS-DP
- SERCOS
- Ethernet
- Service flash module
