3. Check and set the rotor position identification routine via the test
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

is displayed
Save to FEPROM and carry–out a HW–RESET
4. Check the rotor position identification routine via the ramp–up time
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
5. Set the current controller adaptation (refer to Chapter 4.8.3)
– 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 %
