m Method 1
The motor must be able to move free of load in any direction with at least twice the val-
ue of Z127.9– Maximum angle. Reducing Z127.9– to values lower than 0.5° does not
result in a pole position search without motion. This is achieved with method 2.
The current set value is linearly (Z127.5– Current rise) increased to the Z127.4– Max-
imum current. The movement of the motor is minimized by adjusting the electric angle
(Z127.10– Angle rising) during this operation. Based on the starting position the me-
chanical movement is monitored via Z127.13–.
The determination of the notch position is made twice. Both results must be checked
for consistency. If both of the notch positions deviate, a third pole position search must
be done.
Reasons for error 716:
– No conformant notch positions after making three procedures of measuring.
– No conformance check, because of less than two successful measuring.
– The mechanical movement during the procedure is greater than the value of
Z127.11– Error limit mechanical angle change.
– Timeout of 2 minutes for pole position search was exceeded.
Method 1 affects the following factors:
– Notch positions of motor.
– Friction.
– Resolution and quality of encoder signals.
– Setting of current controller see ZAutotuning of Current controller– from page
199.
– Setting of specific parameters for the operating mode Notch position search.
The default values of these parameters (Z127.5– to Z127.12–) are preset ro-
bust enough for the most drive configurations. Therefore, in general, the default
values must not be changed.
m Method 2
Here the injection procedure is provided. See chapter ZNotch position search with the
injection method– from page 645.
