i700 resolver version and FAST Motion: Reference state of Motion axis is reset if encoder parameters differ from default (corrected from V2.10.12)

Corrected from:
i700 servo inverter,  series devices (V02.x):  from V02.10.12.11906
                                  existing devices (V01.x):  from V01.10.12.11905

Response of the new version:
The reference state of the FAST Motion axis is no longer reset if the selected encoder parameter settings differ from the Lenze setting.
 

What happens?
In the Motion axis, the reference state (HomePosAvailable bit) is erroneously reset after power-on.
This will be caused by an i700 internal bit of the encoder evaluation, which will be not reset correctly in case of using resolver variant.
 
When does this behaviour occur?
  • i700 resolver version under FAST Motion,
  • 'Home position after mains switching' mode is set to 'Maintain' (AxisRef subindex 081 = TRUE),
  • The i700 encoder parameter settings (0x2C40, 0x2C42/1, 0x2C42/2) differ from the Lenze setting.
Which products are affected?
i700 servo inverter

Short-term measures:
Do not change the Lenze setting of the encoder parameters in the i700 or reset them to the Lenze setting.

Evaluation/recommendations:
Operation of the i700 resolver version does not require any encoder parameter changes.
