General information
Once the power supply has been connected to the frequency inverter, it will be operational within a few
moments. In this condition, the frequency inverter can be set up for the application requirements, i.e.
parameterised. A complete and comprehensive description of each parameter is set out in the following
sections.
The motor should only be started with the enable signal after the parameters have been successfully set by
qualified personnel.
CAUTION: The frequency inverter is not equipped with a line main switch and is therefore always live when
connected to the power supply.
6.1 Basic settings
All frequency inverters supplied by Getriebebau NORD are pre-programmed with the factory setting for
standard applications with 4-pole standard motors. For use with other motors, the data from the name plate of
the motor must be input into the parameters under the menu item >Motor data<.
Recommendation: For correct operation of the drive unit it is necessary to set the motor data as
precisely as possible (name plate). In particular, an automatic stator resistance measurement
(P208) must be carried out.

Note: In this example, the motor must be "star" wired (400V, P207 = 0).
The frequency inverter is pre-programmed at the factory for standard applications using 4-pole DC standard
motors. If another NORD motor is to be used, it can be selected from a motor list in P200. The data is
automatically loaded into parameters P201
– P208 and can be compared again with the data from the motor
name plate. Then, 0 or no change appears in P200.
When using other motors, the data from the name plate of the motor must be input into parameters P201 to
P208.
In order to automatically determine the stator resistance, set P208 = 0 and confirm by pressing "ENTER". The
value adjusted to the line resistance will be saved (dependent upon P207).
