Frequently asked questions
Can 1FK7042-5AF7Z replace 1FK7042-5AF71-1DB0 without rewiring?
Drop-in substitution is not guaranteed — both are 1FK7042-5AF7x frame motors but the -5AF7Z at 2.27 kg versus the -5AF71-1DB0 at 5.44 kg points to different shaft, holding-brake, and encoder options inside the same stator, so the resolver/encoder cable and brake connector pinout must be checked against the axis wiring before a swap.
