Frequently asked questions
Where can I buy 1FK7100-5AC71-1UA3-ZN01N05 and how do I get a price?
Availability, lot quantity, and current pricing are all confirmed at quote time — no stock count, lead-time figure, or price is asserted on this page. Send the BOM line and required quantity to start a quote.
What is the closest pin-compatible alternative to 1FK7100-5AC71-1UA3-ZN01N05 in this family?
No official pin-compatible successor code is on record for this exact order code. The -Z N05 option ties its shaft dimensions to the older 1FT510x series, which is itself on a similar retirement track; a board-spin to the current SIMOTICS S 1FK2 platform is the realistic replacement path for new machine builds.
Does 1FK7100-5AC71-1UA3-ZN01N05 carry a holding brake?
No. The order code explicitly states WITHOUT HOLDING BRAKE. Any vertical-axis holding function depends on the drive's active braking or an external mechanical brake specified separately.
What are the key ratings on this 1FK7 motor?
Rated torque 18 Nm, thermal class 100 K, rated speed 2000 rpm, continuous power 3.05 kW under natural cooling, resolver multi-pole SMI feedback, IP64 protection, IM B5 flange mounting (IM V1 / IM V3 usable).
