Speed Control and Positioning using standard drives (Set 1)

Highlights:

Simple solution for positioning a linear axis (horizontal or vertical) or a rotary axis.
Clearly reduced engineering overhead by providing a command library for STEP 7 Micro/WIN.
The use of a particularly sturdy control algorithm ensures that a manual optimization of the position control is not necessary even if there are strong load fluctuations.
Realization of the drive task without comprehensive control engineering know-how. The SIMATIC S7-200 takes the position control.
Engineering and commissioning of S7-200 and closed loop positioning control with only one software tool: STEP 7 Micro/WIN.
Cost-effective and high-performance solution with SINAMICS G110.
In addition to your control task, the S7-200 can also solve multiple automation tasks.
Visualization and control of the process via the TP 177micro Touch Panel.

Automation task:

Automation solution:
By means of the Touch Panel TP177 micro, all wire coils available for production including their type and capacity can be stored as a recipe in the voltage-resistant memory module of the S7-200 CPU 224XP. Prior to production, the wire coil to be used for production has to be selected by means of the Touch Panel TP177 micro. During insertion of the wire, a block running in the S7-200 CPU 224XP controls the frequency inverter G110 via an analog interface so that the wire will stop after having passed an inductive sensor and that the positioning axis thus is referenced. The distance over which the axis has been moved will be reported to the S7-200 CPU 224XP as pulses by an HTL encoder. After having entered the production ID, length and quantity of the wire pieces to be produced via the Touch Panel TP177 micro, a block running in the S7-200 CPU 224XP will induce the frequency inverter to move the positioning axis over the desired length of the wire. Via a digital output signal, the S7-200 CPU 224XP then controls a cutting device which will cut the wire. This process is repeated according to the quantity entered. After production has been completed or after an interruption, all production parameters such as e.g. the setpoint and actual quantity of the produced wire rods will be stored in the voltage-resistant memory module of the S7-200 CPU 224XP. The thus buffered information can be read via serial coupling by means of a PC/PPI cable and the STEP 7 Micro/WIN tool S7-200 Explorer and can be stored as a CSV file. After production has been completed, the residual wire coil capacity is stored in the voltage-resistant memory module of the S7-200 CPU 224XP. If the wire quantity is not sufficient for the planned production, this will be indicated via a corresponding message at the Touch Panel TP177 micro.
