Hiperface DSL (OCT): Previously existing reference is lost after switching to mains (corrected from V01.04.01)
Corrected from:
Servo Inverter i950 FW: from V01.04.01.1471
Response of the new version: Hiperface DSL (OCT): Bit 5 "Motor enc abs. pos. avail." in the "Inverter status word 2" (0x2833) is now set correctly. The reference jam is no longer erroneously lost after power switching.
What happens? Absolute value encoder Hiperface DSL (OCT): After booting the device bit 5 "Motor enc abs. pos. avail." is set. in the "Inverter status word 2" (0x2833) is not set correctly. This signals that the absolute position does not exist and that a new referencing is necessary
When does the behaviour occur? After switching on (booting) the device, e.g. by switching the 24V power supply.
Which products are affected?
Servo-Inverter i950 FW
Short-term measures / Evaluation / Recommendations: The described behaviour only occurs after switching on (booting) the device. Bit 5 (motor enc abs. pos. avail.) is set correctly after an encoder error has been occurred. By initiating an encoder error (disconnect encoder plug and reconnect) it is possible to circumvent the above described behaviour.
