Manual "current/frequency" test mode
Preconditions for the performance
•
The motor must rotate freely.
•
The inverter is error-free and in "
" device state.
Functional description
In this test mode, three phase currents are injected into the connected motor after the inver-
ter is enabled.

Advantages compared to the manual "voltage/frequency" test mode
•
The current cannot be set freely but is adjusted to a defined value.
•
If a synchronous motor is connected, it is possible to predict the torque.
Response of the motor during performance
•
The motor moves as a function of the set output frequency.
After the inverter has been enabled, the synchronous motor makes a jerky com-
pensating movement if its pole position does not correspond to the starting
angle.
How to activate the manual "current/frequency" test mode:
1
.
Disable inverter
2
.
Change to the "current/frequency" test mode.
3
.
Enable the inverter to start the test mode.
4
.
To stop the test mode again:
•
Disable inverter.
•
Change back to the CiA402 operating mode.
