13.11.2
Manual "tension/frequency" test mode
Functional description
In case of devices that correspond to the "dual use regulation" (EC 428/2009),
values higher than + 599 Hz up to lower than - 599 Hz do not increase the out-
put frequency. Please observe the deadband occurring in this case.
Further information can be found in the section "
".
After the controller is enabled in this test mode, a rotary field voltage is output at the motor
terminals with the set output frequency f
out
.
•
If the selected frequency is positive, the motor should rotate clockwise when looking at
the A side of the motor. If this is not the case, the motor phases are connected incorrectly.
•
The output voltage level is determined by the following equation

The manual "voltage / frequency" test mode also serves to check the wiring of the feedback
system.
•
If the feedback system of a synchronous motor is set correctly, an actual speed should be
displayed that can be calculated with the following equation (if the feedback system of an
asynchronous motor is set correctly, the actual speed is a bit lower due to the slip):

Conditions for the execution
•
The motor must rotate freely.
•
The servo inverter is error-free and in the "switched-on" device state.
Response of the motor during performance
The motor moves as a function of the set output frequency.
How to activate the manual "voltage/frequency" test mode:
1
.
Disable the inverter
2
.
Change to the "voltage/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".
