High-dynamic Two-channel Servo Drives for Tightening Systems in the Automotive Industry
Customized Servo Drives
On behalf of a client SIEB & MEYER has developed a double-axis servo drives to be used as central component in a two-channel tightening (nutrunner) system.
Client requirements:
The client planned a compact two-channel tightening system using his own control card and a double-axis servo drive purchased in addition. The servo drive should work as central component with integrated control technology.
In addition, the client required a device that makes two different installation concepts possible – a switch cabinet version with IP20 housing and a board solution to be installed in the client's device housing.
The servo drive should operate servo motors with speeds up to 40,000 rpm. Due to the application the motor as well as the driving servo drive require a high overload capacity – the construction volume, however, should remain quite small.
The client uses motors with various power and voltage data and wished for a servo drive that is optimally adapted to these conditions. Beside high availability, the devices must provide scalability and excellent quality of current feed.
The customized solution by SIEB & MEYER:
SIEB & MEYER assisted the client from the design phase to serial production. In cooperation the partners developed a customized system solution. The customized development is based on the well-proven technology of the servo drive series SD2 that was especially designed for multi-axis applications.
There are six different device variants based on the output stages of the series devices. All six cards use the same PCB layout but have different equipment variants, which makes the greatest number of common parts possible.
The drive and the measurement and control group are accommodated in a common, compact housing – this saves installation space, makes external wiring redundant and ensures quick and trouble-free exchange of the unit when service is required.
Together the companies developed the hardware and software interface for the control card enabling a flexible access to all process-related objects of both tightening channels. This way the client can implement his application software easily by himself.
The most important details in short:
- customized double-axis servo drive
- three power ranges and two different installation concepts
- input: 3 x 230 VAC and 4 x 400 VAC, 50/60 Hz
- max. rated current/peak current (5 s): 2 x 7/42 Arms
- hardware and software interface to the client's control card
