Typical application


1. Automated production line
The Siemens 1FL6090-1AC61-2LB1 absolute encoder can continuously provide precise position feedback to the servo system, enabling the motor to complete accurate starting, stopping, positioning, and speed adjustment according to the control system instructions. It can also perform material feeding, positioning, sorting, handling, and actuator drive.

2. Packaging machinery
The motion sections include film conveying, material feeding, cutting, packaging, labeling, and packaging mechanism positioning. For packaging equipment that requires coordinated operation of multiple motion axes, it can be used in conjunction with the SINAMICS V90 servo drive system to achieve stable synchronous motion.

3. Conveying and sorting equipment
For conveying equipment that requires frequent start-stop, positioning, and speed variation, servo control is more suitable for precise motion control compared to ordinary constant-speed motors. It can be used to drive conveying shafts, drums, synchronous belts, or other mechanical actuators, using encoder feedback to help the control system accurately determine the position and motion state of the motor.

4. Precision positioning equipment
It can provide high-resolution position feedback to the control system, enabling precise positioning of mechanical mechanisms. It includes automatic positioning platforms, mechanical hands, pick-and-place mechanisms, processing positioning mechanisms, and automatic adjustment mechanisms. For equipment requiring high repeatability positioning accuracy, system-level precision design can be carried out in combination with specific mechanical structures, reduction mechanisms, and controllers.

5. Material handling system
It is equipped with a holding brake with a torque of 30 Nm. In vertical lifting or mechanical mechanisms that require maintaining position, the holding brake function can be used reasonably based on the overall safety design and load conditions of the entire machine.

6. Machine tools and mechanical equipment
The Siemens 1FL6090-1AC61-2LB1 can be selected based on the load curve and motion requirements of the equipment. It adopts a permanent magnet synchronous motor structure, with a rated speed of 2000 rpm, a maximum speed of 3000 rpm, a rated torque of 11.9 Nm, and a maximum torque of 35.7 Nm.

7. Multi-axis motion control system
It can configure different power levels of servo motors based on the load, speed, inertia, and motion cycle of the mechanical axes.

8. Servo positioning system
It consists of an absolute encoder, servo driver, and controller, forming a closed-loop motion control system, which can be used for equipment requiring precise speed, position, and torque control. Its 90 mm shaft height, IM B5 installation method, angle connector, and shaft end with a sliding key are also convenient for installation and integration with the corresponding mechanical structure.

Procurement precautions for replacing the module


When purchasing Siemens 1FL6090-1AC61-2LB1, do not replace only the 2.5kW servo motor. For the same 1FL6090 model with 2.5 kW power, the configurations such as encoder, shaft end type, and holding brake may vary. If you encounter the problem of production suspension, you can inform us, and we will find out a reasonable plan for you.
