gefran ADV200 Functions Description And Parameters List

6 ADV200 • Functions description and parameters list
Practicalexample
The following examples illustrate the philosophies and methods with which more or less complex operations
are performed in the single “function blocks”, the results of which represent the output of the block.
• Example: Changing the Speed Reference source
The main drive reference (in the default conguration) Rampref1mon(PAR: 620) is generated by the output
of the function block “RampsetpointBlock”.
Its default source is the Analoginput1mon signal (PAR: 1500), from the output of the function block “Analog
input1Block”, which in this case refers to analog input 1 of the signal terminal strip.
To change the reference source from the analog input to a digital reference inside the drive, the input signal
must be changed to “RampsetpointBlock”.
Enter the Rampref1srcparameter (PAR: 610)and set a new reference, selecting it from among those listed
in the L_MLTREF selection list, for example Digrampref1(PAR: 600).
• Example: Inverting the analog reference signal
To invert the “Analoginput1Block” output signal, the value of the Aninp1signsrcparameter (PAR: 1526),
which has a default setting of Null (no operation), must be changed by selecting the source of the command
signal from among those listed in the L_DIGSEL 2 selection list, for example DigitalinputXmon, One(func-
tion always enabled), etc.

The diagrams above illustrate the internal processing philosophy of the single “function blocks” and the result of
these changes on the other interconnected “function blocks”.
Note ! This section contains a brief description of the functions of the other parameters in the function blocks not included for the
changes in the example
The Aninp1altselsrc parameter (PAR: 1528) can be used to select an alternative reference for the Analog
input1mon(PAR: 1500) output.
The Aninp1altvalueparameter (PAR: 1524) determines the alternative reference value for the Analoginput
1mon(PAR: 1500) output.
The Ramprefinvertsrc parameter (PAR: 616) can be used to select the source for the command to reverse
the “Rampsetpoint” function block output.
The output signal from the “Rampsetpoint” block is displayed in the Rampref1monparameter (PAR: 620).
