The power and signal connector on the housing is a rotatable plug, turnable through roughly 270°, which lets the wireman orient the cable exit for the cabinet routing without re-machining the mounting footprint — a small detail that matters when this is a drop-in replacement on a line that was already wired. ## 36 Nm at 3000 rpm and what that means on the line 36 Nm at 3000 rpm puts this frame in the mid-power bracket of the 1FK7 Compact line — sized for machine-tool spindles, packaging axes, and conveyor sections where a dynamic, position-controlled drive replaces a slower induction-geared solution. Naturally cooled means the continuous rating holds without a forced-air duct on the machine frame; the thermal envelope is set by the motor surface area to ambient, so when the cabinet layout traps heat or the duty cycle climbs above the 100 K class assumption, the continuous torque must be derated or the motor overspecified at the next frame size.","metaTitle":"1FK7103-5AF7.-1...
