New brushless drives for low power servo applications
February 2007
Motion Control & Drives
The SERVOSTAR 200 brushless servo drives push high performance servo technology into lower power applications than was previously possible without having to compromise on reliability or package size. Couple a SERVOSTAR 200 drive with a AKM servo motor for a complete servo control solution designed for applications such as semiconductor fabrication, electronic assembly, packaging, medical, and woodworking equipment.
The SERVOSTAR 200 servo drives are one of the first all digital industrial drives with a velocity loop bandwidth up to 800 Hz offering unmatched system throughput and simplified tuning. High resolution (24 bit) feedback and high performance 3-5 kHz current loop bandwidth provide smooth motion, and rapid start and stop action to optimise machine performance. Smart feedback and industry leading high bandwidth deliver fast and accurate commissioning by eliminating the need for servo loop tuning in most applications.
Separate 'Keep Alive' power input allows rapid recovery from emergency stop conditions. Optically isolated inputs/outputs, positive locking connectors and full fault protection promise long machine life and immunity to accidental damage. A single motor power/feedback cable simplifies connectivity. All connectors and LED status indicators are easily accessible from the front of the drive.
Increased machine throughput and longer life servo system performance is synonymous with machine throughput. The SERVOSTAR 200 family ensures servo performance.
* Industry-leading current loop bandwidth up to 5 KHz and velocity loop bandwidth up to 800 Hz means machine throughput can be increased by as much as two to three times.
* Robust design including full fault protection, locking connectors and optical isolation promise greater machine 'up-time'.
* Smooth motion, a benefit of sinusoidal current control and high resolution (24 bit) feedback minimises harsh torque disturbances that can cut short the life of mechanical components.
* Both the AC and the DC input drives are equipped with separate control power input to speed recovery from 'E-Stop' conditions.
Reduced engineering and support time
Simplified tuning, friendly graphical user interface and shared components with stepper products.
* Windows-based Graphical User Interface models the tree format found in Explorer so learning is quick and easy.
* Easy to debug with full fault diagnostics reduce engineering support time.
* Shares option cards, electrical I/O, and GUI components with the P7000 stepper drive family reducing the time required to learn new products.
CE/UL conformity
SERVOSTAR meets all relevant standards:
* EMC Directive 89/336/EWG.
* Low Voltage Directive 73/23/EWG.
* UL/cUL pending.
