If you disconnect the motor from the ball screw, the physical relationship between the encoder and the machine zero changes.
Absolute encoders rely on a backup battery to "remember" their position when the power is off. If the battery dies, the position is lost.
When a machine is equipped with absolute encoders, it does not require a manual "home" or zero-return operation every time it is powered on, provided the absolute position is correctly saved. Parameter 1860 is the system's "flag" that tells it whether this position is currently valid. 1. The Core Meaning of Parameter 1860
In a perfectly functioning machine, this parameter stays at "1" indefinitely. However, certain events will force it to "0," requiring a re-homing procedure:
AAI Cargo Logistics and Allied Services Company Ltd. (AAICLAS) was incorporated on 11th August 2016 as a 100 % subsidiary of Airports Authority of India. Keeping in mind the economic boom, the importance of Air Cargo and its impact on the overall Economy of India, AAICLAS was carved out of the Airports Authority of India as a separate Company to meet the challenges of the future.
