Adapt pole posion idencaon PLI (min. movement)
The process of pole posion idencaon described above can be adapted to the respecve
machine and the exisng moments of inera by using the parameters described in the follow-
ing.
NOTICE
Thermal overload of the motor!
The mot

▶
If no temperature monitoring is available in the motor, and/or the I²xt motor monitoring
and the maximum current monitoring are not parameterised correctly, the motor can be
permanently damaged if the current amplitude is set too high!

idencaon (min. movement) sengs:
Current amplitude
1 ... [25] ... 1000 %
•
Seng can only be changed if the inverter is inhibi-
ted.
Percentage adaptaon of the current amplitude.
•
For large machines, high mass inera values or for linear direct drives,
the current amplitude usually must be increased.
•
Default seng 25 % ≡ 35 % of Motor rated current (0x6075)
Note!
If the current amplitude is set to > 100 %, the device ulisaon (Ixt)
monitoring and/or one of the motor monitoring funcons may respond
and cause the abort of the pole posion idencaon.

Gain
0 ... [0] ... 1000 %
Adaptaon of the proporonal PI controller gain.
With the Lenze seng "0 %",the PI controller works as an I controller.

Reset me
0.1 ... [62.5] ... 6000.0 ms
Adaptaon of the reset me of the PI controller.
•
In order to be able to compensate a posional variaon faster, rst
the reset me should be reduced. If this does not result in the desired
behaviour, the proporonal gain can be increased.
•
Ensure that the posion control does not get unstable. We therefore
recommend you to use an I controller.
0x2C62:005 Pole posion idencaon (min. movement) sengs:
Max. move permied
1 ... [20] ... 90 °
Adaptaon of the permied movement.
•
The pole posion idencaon comprises a monitoring funcon for
the follow-up control. If a movement greater than the permissible
movement set is detected by the encoder system, the pole posion
idencaon is aborted and the error response parameterised is trip-
ped:
•
In order to detect a non-permissible blocking of the machine, a posi-
ve and negave test angle relave to the current posion are
dened aer the idencaon. The machine must align itself to these
two test angles within a tolerance of 25 %. The size of the test angle
corresponds to the max. move permied set here.
