Hiperface DSL (OCT): After booting, error code 0x7381 occurs and cannot be reset (corrected from V01.05.02)
Corrected from:
Servo inverter i950 FW: from V01.05.02.1788
Response of the new version:
Error 0x7381 no longer occurs unexpectedly during booting.
What happens?
Immediately after booting the i950, monitoring responds with the following error message, although the encoder position has not changed:
0x7381 "Hiperface absolute value not valid because motor speed is too high at slot A"
When does the behaviour occur?
One cable technology (OCT):
Absolute value encoder Hiperface DSL is used as motor feedback (0x2DE1:1 = 10: Hiperface DSL).
When powering-on the device (Boot-up).
Which products are affected?
Servo inverter i950 FW
Short-term measures / Evaluation/ Recommendations: There is no known remedy. The behavior does not necessarily occur with every boot and is therefore not necessarily detected during commissioning.
Hiperface DSL encoders (OCT) can not be used with the affected firmware versions of i950.
