Responses of the motor during performance
Remove the mechanical xaon aer the current controller has been adjusted!
The motor usually aligns itself only once with the rst controller enable.
How to adjust the current controller by means of the manual test mode "current pulse":
•
Disable inverter.
•
Calculate start parameters for the inverter based on the parameterised motor data.
•
The automac calculaon is made via the parameter 0x2822:013.
•
You can determine the start parameter manually.
•
Change to the "current pulse" test mode. 40x2825 = 3
•
Set the setpoint current for the manual test mode. 40x2835:001
•
Enable the inverter for a short while to start the test mode.
•
Measure the step response of the motor current in the motor phase U by means of an
oscilloscope and a clamp-on ammeter.
•
Evaluate the step response.
•
Adjust the gain and the reset me of the inverter.
•
Repeat steps 1 ... 6 unl the opmum step response of the motor current has been
reached.
•
Exit the test mode:
•
Disable the inverter.
•
Change to the CiA402 mode. 40x2825 = 0
•
For permanent saving: save changed current controller parameters.
