08/11/2011 - Upgrade package for autoleveler draw frames

The "AC SERVOcombi" upgrade package for older generations of draw frames ensures very high production rates through precise autoleveling and operating reliability.

Servo controller G90 for the "AC SERVOcombi"

The "AC SERVOcombi" upgrade package consists of a state-of-the-art servo motor and a new control unit. An ideal combination representing the latest state of the art in AC servo motors.

The "AC SERVOcombi" motor

The powerful "AC SERVOcombi" motor for autoleveling achieves higher efficiency through its sustained, powerful torque throughout the entire speed range. Positioning is by means of a rotary transducer, which ensures a constant actual-value comparison. The servo drive therefore follows the preset autoleveling profile precisely. Perfectly leveled draw frame slivers are the result.

The "AC SERVOcombi" motor offers further advantages:

• very quiet running properties
• high dynamics
• very homogeneous control behaviour

The "AC SERVOcombi" motor is an AC servo motor. Carbon brushes are elimated, making this type of servo motor completely maintenance-free.

A further element contributing to reduced maintenance time is the electronic control of the new G90, which replaces the mechanical motor brake used to date. The components of the "AC SERVOcombi" motor are designed so that overheating cannot occur in extreme environments.

The control unit for the "AC SERVOcombi" motor

The new servo controller supplied with the motor and the "AC SERVOcombi" motor are ideally coordinated. Signal processing is performed in the digital servo controller in real time. The measuring signals are therefore precisely coordinated with the setpoints and this results in very accurate autoleveling.

Easy installation

The motor's compact design and the pre-wired servo controller on a baseplate facilitate user-friendly and rapid installation. Customers benefit from a short installation time and rapid return to production of the draw frame after conversion. It is worthwile adjusting autoleveling quality to the current state of the art on older draw frame models.

The "AC SERVOcombi" upgrade package is available for the following autoleveler draw frames with DC-servo motors: RSB 51, RSB 851, RSB 951, RSB 1, RSB-D 30, RSB-D 30c, RSB-D 35 and RSB-D 35c.
