5.3.3.1 Adjustment of the pole position identification
This function extension is available from software version V4.0!
The two procedures for Pole position identification (PPI) described in the previous sections can be
adjusted to the respective machine and the prevailing moments of inertia by means of the
parameters described below.
In the Lenze setting of the parameters, the pole position identification remains the same as in
software versions < V4.0.
Parameters for the pole position identification 360°
• The current amplitude can be adjusted proportionally in C00641 .
• For large machines and high mass inertia values or for linear direct drives, the current
amplitude usually has to be increased.
• The Lenze setting "100 %" corresponds to the smaller of the two following values:

Note!
The two procedures for the pole position identification should give the same results. But,
due to e.g. friction, bearing forces and a trapezoidal field pattern, the results may differ.
A proportional increase of the current amplitude in C00641 or C00646 can counteract
this deviation.

If there is no temperature monitoring in the motor and/or the I

xt motor monitoring and
the maximum current monitoring are not parameterised correctly, the motor may be
permanently damaged when the current amplitude is set too high (e.g. to the maximum
value)!
