Lifecycle read on 1FK7062-2AH7.-....
The catalog line for 1FK7062-2AH7.-.... carries eol_hot, which is the entry that drives the BOM-side decision: do not write this into new builds without a confirmed LTB window and a fallback drive package sized for the same shaft and encoder profile.
Decoding the 1FK7-CT nameplate string
The descriptor in the record reads SIMOTICS S Synchronous motor 1FK7-CT, PN=1.4 kW, UDC=600 V, M0=8.5 Nm (100 K), NN=4500 rpm, naturally cooled — a compact, self-cooled high-dynamic servo sized for SINAMICS S120 line-side converter operation at the 600 V DC-link class. 8.5 Nm stall at the 100 K winding rise and 4500 rpm rated speed put this 1FK7-CT frame in the mid-range positioning / feed axis slot — typical machine-tool changeover, packaging indexing, and small-format pick-and-place duty where the cycle budget is set by torque, not continuous power.
Where a naturally-cooled 1FK7-CT typically lands
Naturally-cooled SIMOTICS S motors of this frame are deployed on machine axes where cabinet airflow is restricted and the motor is mounted away from the drives rack — the convection-only thermal path makes the M0 figure and the duty cycle, not the continuous kW, the design constraint.
