8.6 Reading Data From Control Unit
„Parameter transmission“ enables the transmission of parameter values from the control unit KP 500
to the frequency inverter. In this operation mode, all other functions of the control unit are disable,
except for the COPY function. Transmission from the frequency inverter to the control unit is also
disabled.
Activation of the control unit KP 500 for parameter transfer is prepared via parameter Program 34.
