6. Configuration
For correct function please consider the required setting of
•
Operation mode
•
Input for Set Value
•
Maximum input frequency of encoder
and place the according jumpers at the front side of the drive, where :
* means...set Jumper -- means remove Jumper.

J12 is responsible for the filtering of the output signal of the encoder/tacho conversion module. If it is
set, the quality of the signal is better but the dynamic range is reduced due to the lowpass response.
Example: resolution 500 counts per revolution (cpr)
nmax = 2520 round per minute (rpm)
maximum frequency: (2520 rpm * 500cpr) / 60 = 21000 Hz = 21 kHz
jumpers 7,8,9 and 10 have to be placed to get the desired signal
