General settings for test modes

Wiring check by means of manual test modes
Before starting the parameter setting of the inverter, check the motor wiring (motor connec-
tion / feedback connection) for errors and function and correct them if required:
1. Provided that the motor is connected in correct phase relation and the rotating field fre-
quency is positive, the motor shaft rotates clockwise.
2. An existing speed feedback in the rotor position () generates a numerical value with posi-
tive counting direction. If required, take corrective measures: see the table at the end of
the list.
3. After the controller inhibit (0x6040) has been activated, the following manual test modes
are available via the parameter 0x2825:
Manual "tension/frequency" test mode
•
Manual "current/frequency" test mode
•
The parameters for the test modes can be adapted via the parameter . Please observe the
notes in the description of the respective test mode.
