Where this motor lives on the machine
The 1FK7043-4CK71-1CH1 is a high-dynamic synchronous servo motor in the Siemens 1FK7 family, specified for the motion axis on machines where the drive must accelerate and reverse a load faster than a general-purpose induction servo can. Position-hold, contouring, and indexing axes on packaging, converting, and machine-tool slides are the typical deployments for this frame size.
Lifecycle and what EOL/hot means for the order
Stock on the manufacturer channel is no longer the sourcing baseline; independent distribution carries the residual new-surplus and factory-traceable inventory until it is exhausted.
Sourcing posture for an EOL/hot servo
There is no factory-direct line to lean on once EOL/hot is in effect — the lead time and quantity conversation lives with the distributor carrying the residual stock.
