Corrected from:
Servo Inverter i950 FW: from V01.04.01.1471
Response of the new version:
Changed settings of the motor parameters are now immediately effective without a renewed initialization of the drive controller.
What happens?
Changed settings of the motor parameters only become effective after a new initialization (power switching).
If, for example, the motor mass moment of inertia 0x2901:1 = 0 is set, then the torque pre-control is still effective based on the motor mass moment of inertia (0x2901:1) and the current acceleration existing at the last power-up.
When does this behaviour occur?
Changes to the motor parameters only become effective after a new initialization (power-on).
The value from 0x2901:1 is only accepted when the device is started or when TA switching over via 0x4000.
Which products are affected?
Servo inverter i950 FW
Short-term measures, Evaluation/recommendations:
Set 0x2901:1 via 0x4000 before the TA changeover or after the motor parameters have been changed, switch to mains or execute the function 'Restart Device' ( 0x2022:35 = 1:On).
The described behaviour must be taken into account if the torque pre-control is to be deactivated during operation or if motors from other manufacturers are used, in which a Lenze motor is first preset and then the motor parameters are adjusted.
