Set the following values for the respective parameters if a frequency value is needed for the
further processing:
Table 8- 13 parameter setting for digital tachometer with frequency value
Parameter
Value
"P-PULSE INPUT/Mode"
"f > 20 kHz"
"P-PULSE INPUT/Max.plse."
"25,600 Hz"
"P-PULSE INPUT/Pulses/360"
"1024"
The frequency is available for further processing as "Freq.act." from 0 Hz to 25.6 kHz and as
"Pulse act" from 0 % to 100 %.

Setpoint channel and closed-loop control
8.6.1
Specifying source for speed setpoint
Specify under "P-SPEED DEFAULT//n Set source" the setpoint source to which the inverter
must react, e.g. including:
●
"Internal" using <up arrow> or <down arrow> of the display
●
"AI 1" via analog input 1 of the control terminal block -X2
●
"BUS 1" as control word via the optional fieldbus connection

Principle of operation of the configuration
NOTICE
Incorrect parameter settings
The converter and other connected components can be damaged or destroyed if the
parameter settings are incorrect.
Only qualified personnel may change parameters; the instructions in the Operating Manual
and the technical data of the converter and connected components must be carefully
observed.
Parameterization is based on the principle - Input
→ Processing → Output. Many functions in
plain text are available in the bit pool for the input. You always have the selection from the bit
