function
To check the rotor position identification, using a test function,
you can determine the difference between the calculated rotor
angle position and that actually used by the closed–loop control.
Proceed as follows:
– Start the test function several times and evaluate the difference
Start Set P1736 (test rotor position identification) to 1
Difference P1737 (difference, rotor position identification)
= _ _ _ _ , _ _ _ _ , _ _ _ _ , _ _ _ _ , _ _ _ _
– Is the spread of the measured values less than 2 degrees electri-
cal?
Yes: OK
No: Increase P1019 (e.g. by 10 %)
and repeat the measurements
If OK after having repeated the measurements, then the
angular commutation offset can be re–determined:
For an incremental measuring system:
as for Point 2. (determining the angular commutation off-
set)
For an absolute measuring system:
Power–down the drive (POWER ON–RESET)
Power–up the drive with the pulse or controller enable
signals switched–out
Set P1017.0 to 1
Switch–in the pulse and enable signals
––> The angular offset is automatically
entered into P1016
––> Fault 799
(Save to FEPROM and HW–RESET required)
is displayed
Save to FEPROM and carry–out a HW–RESET
measurement
In order to check the rotor position identification routine, the
ramp–up time measurements can also be made in both directions of
rotation.
Objective:
Set P1016 so that the ramp–up times in both directions of rotation
are approximately the same
– P1120 is pre–set with "Calculate controller data"
– Check the pre–setting for the current controller adaptation
(the values were already entered together with the motor data):
P1180 = 0 %, P1181 = 30 %, P1182 = 30 %
