ICS TRIPLEX 9852 Alternating Current Servo Drives

ICS TRIPLEX 9852 is a very mature application of a speed control technology, due to its unique advantages in speed control, in many speed areas are widely used, frequency control controller is a typical application. The two design schemes mentioned in the paper are representative: the isolation scheme is more mature and has more applications, but the hardware cost is relatively high; the common ground scheme based on a single power supply IPM module is much more attractive, and under the premise of meeting the performance, it can minimize the hardware cost, which greatly improves the market competitiveness of the product.

The ICS TRIPLEX 9852 upper plaque is fully reversible for scrubbing and changing rollers and has an adjustable tilt. The lower plaque can move up and down on the guide rail driven by worm gear elevator, and there is one inlet and one outlet respectively. The opening degree of the inlet and outlet is adjusted, that is to say, the size of the roller gap of the lower straightening roller relative to the upper straightening roller is adjusted, so as to change the degree of bending of the copper strip, and the adjustment amount is completed by the servo positioning. The lower roller is also installed in the deed-shaped adjustment block, the local plate shape of the micro-adjustment, through the displacement sensor feedback its actual adjustment position.

The ICS TRIPLEX 9852 uses a Siemens S7-200 CN and uses a positioning module to control the AC servo drive for precise positioning of the AC servo motors, and an EM235 module to collect the feedback signals from the displacement sensors to control the amount of fit adjustment. The three fit adjustments are driven by three AC motors, and an AC inverter is used to control the rotation speed of these three motors at the same time.
