How to control the frequency inverter with the ParameterBox
Complete control of the frequency inverter with the ParameterBox (involving speed and phase sequence of the
motor) presupposes that the (P509) >Interface< parameter has been set to the function >Control terminals or
keyboard< (= 0) which as far as the NORDAC SK 300E and SK 700E are concerned is the default setting
made in the factory, and that the inverter has not previously been enabled via the control terminals.

If the frequency inverter is enabled in this mode of control, the set of parameters used will be the
one for this particular inverter in the >Parameter set< (P100) parameter which is found in the >Basic
parameters< section of the >Parameterisation< menu. If the operator wished to switch to a different
parameter set while operation is going on, the same parameter (P100) must be accessed, the new
parameter set selected and then activated with any of the following keys: , or .
Caution: On receiving the START command, the frequency inverter may start up immediately
supplying the frequency which has been programmed before, if any (minimum fre-
quency P104 or start-off frequency P113).
