Frequently Asked Questions

What advantages does the multiturn optical EnDat 2.1 encoder (2048 signal periods) provide for MSK100A-0200-NN-M2-AG1-RNNN?

The EnDat 2.1 supplies absolute multi-turn position plus fine incremental interpolation for improving commutation and velocity ripple at low speed. Its optical scanning yields very fine graduation periods for precise feedback to compatible IndraDrive controllers.

How is DIN 42955 “increased concentricity and run-out” relevant to coupling the MSK100A-0200-NN-M2-AG1-RNNN to precision loads?

The DIN 42955 defines tolerances for shaft concentricity and flange run-out (classes N/R) for reducing eccentric loading on couplings, ballscrews or gear stages. Its better run-out minimizes excitation of torsional resonances in precision axes.

What does the A-side power connector imply for cabinet and cable routing on MSK100A-0200-NN-M2-AG1-RNNN?

The A-side orientation simplifies straight-through routing in tight machine frames and can reduce bend radius stress. It is important to follow Rexroth cable kits and EMC guidance for separation from encoder leads.

Why specify an electrically released 32 Nm holding brake on MSK100A-0200-NN-M2-AG1-RNNN?

The electrically released brake provides secure static holding when power is off to support vertical Z-axes or suspended loads. Its 32 Nm capacity helps maintain position through controlled stops and during maintenance.

Why might a plain-shaft MSK100A-0200-NN-M2-AG1-RNNN be chosen over keyed variants in automation lines?

Its plain shafts pair well with zero-backlash clamping couplings for reducing fretting and keyway stress under reversing duty. It supports smooth torque transmission into ballscrews or gearheads meeting DIN run-out constraints.
