200 Operating Instructions ACU 12/16
16.5.3 Table of functions
With the table of functions, external analog or digital signals and internal logic signals of the
frequency inverter can be linked to one another. Apart from standard AND, OR and XOR
combinations, various complex logic functions such as RS Flip Flop are available. The corresponding
output value can be used for other logic instructions and digital outputs. Logic instructions can be
combined to one another so that any complex links can be realized.
Up to 32 instructions enable flexible adjustment for linking different input signals.
Analog functions include, for example, comparisons of analog input values, mathematical functions,
PID control functions, filters, control of positioning functions limitations, switches and counters.
Example:
A drive is to start if
 release is given AND S5IND is set
OR
 release is given AND S6IND and MFI1D are set.
For a detailed description, refer to the application manual “Function Table”.
16.5.4 Multiplexer/demultiplexer
The multiplexer/demultiplexer enables the transfer of various digital signals between an overriding
controller and frequency inverters via field bus or between frequency inverters via the system bus.
For parameterization of the multiplexer and demultiplexer using the VTable application, the
commissioning and diagnosis software VPlus, version 4.0.2 or higher is required.
Multiplexer:
The multiplexer features 16 inputs for logic signals or digital input signals.
On the output, the logic signal 927 – Output MUX for the inputs of the TxPDO process data of the
system bus or for PZDx-IN process data of the Profibus can be used
.
Operation mode Factory setting
1252 Mux inputs 7 - off
Parameters Mux Input Index (write)
1250 and
Mux Input Index (read)
1251 for the input signals of
the multiplexer enable parameterization via the control unit KP500 or the application VTable in
VPlus.

non-volatile (fixed parameterization): Volatile:
0: all indices in EEPROM 17: all indices in RAM
1…16: On index in EEPROM 18…33: Index 1…16 in RAM
NOTICE
Setting "0" for
Mux Input Index (write)
1250 will change all data in EEPROM and RAM.
In the case of non-volatile storage (0..16), the changed values are still available when
power supply is switched on again.
In the case of volatile storage (17…33), the data is only stored in RAM. If the unit is
switched off, this data is lost and the data required are loaded from EEPROM.
