Micro Automation Set 26

V1.0 (Version 07/2004)

Preamble

Micro Automation Sets are fully functional and tested automation configurations based

on A&D standard products for simple, fast and inexpensive automation tasks for small-

scale automation. Each of these Micro Automation Sets covers a frequently used

subtask of a typical customer automation task in the low-end range.

The sets help the customer answer the following questions for these subtasks: “Which

products do I need?” and “How do the products work together?”

However, depending on the requirements of the system, a variety of other

components (e.g., other CPUs, power supplies, etc.) can be used to implement the

functionality on which this set is based. See respective SIEMENS A&D catalogs for

these components.

Note

When simultaneously connecting PG/PC and TP 170micro (and frequency

inverters) to the controller, do not use the "TP 170micro to CPU" connecting

cable specified in the 'Accessories' list. For this purpose, a Profibus cable must

be prepared individually.

Order two Profibus connectors instead of only one specified in the "Accessories"

list and correspondingly more Profibus cable as well.

Note

The configuration, as it is, is intended for industrial application. For energy

supply, industrial networks are usually implemented here. It is therefore not

necessary to use special filters/inductors with low leakage currents.

If the configuration is used in sensible networks (e.g. PCs on the same network),

filters or inductors should be used.

Note

Standard motors with 400V/230V star/delta winding have to be connected

to the inverter in a delta connection ( 230V).

Warning

What should be done to prevent electromagnetic interference:

• Make sure a good conductive connection between the inverter and the

(earthed) metal mounting plate is provided.

• Make sure all devices in the cabinet are earthed using short earthing lines

with a large diameter and are connected to a common earthing point or

earthing bar.

• Make sure the S7-200 CPU connected to the inverter is connected to the

same earthing or earthing point as the inverter using a short line with a large

diameter.

• Please use shielded control lines, e.g. a SIEMENS Profibus cable for setting

up the RS485 bus.

• Run control lines as far separated from power cables in separate installation

channels as possible. Crossings between power and control lines should be

at 90° angle.

• Connect the protective conductor of the motor to the earth connection (PE)

of the respective inverter.

• The line ends should be properly terminated and unshielded lines kept as

short as possible.

• Use shielded lines for motor connections, earth the shielding both on the

inverter and the motor side using cable clamps.

Method of Function

The configuration consists of a S7-224 XP CPU and four SINAMICS G110

drives. Visualization is provided through TP 170micro.

All SINAMICS G110 drives are coupled to the S7-224 XP CPU through a

serial RS485 interface on which the USS protocol is run. The S7-224 XP

CPU controls each individual inverter depending on the desired

performance. This makes it possible to successively switch on the drives or

to control the speed.

Moreover, precise dosing and energy-saving response are thus enabled

depending on the need. See following figures (an applicative example of

water supply):

The following figure shows the setpoint value of water drawing-off,

represented in the first diagram in green. The four further diagrams show

the four setpoint values of individual drives (red) depending on the setpoint

value of the water drawing-off.

(The diagrams only show the setpoint values specified by the S7-200 CPU

for the frequency inverters. The inverters use ramps parameterizable for

the start and slowdown).

Figure 3-2 setpoint values according to the performance needed

The peaks of the setpoint values of individual motors result from the fact

that a motor operation at a low speed is avoided.

If, for example, a total setpoint of 105% is predefined, motor 1 does not run

at 100% and motor 2 at 5%, it rather means that motor 1 operates at 55%

and motor 2 at 50%.
