Frequently Asked Questions

What are the thermal/installation implications of the “NN” natural-convection cooling on MSK100B-0200-NN-M2-BP2-RNNN?

The conduction surface radiation carry heat to ambient, so cabinet and machine airflow clearances matter to preserve the 33 Nm standstill rating. It allow blower or liquid upgrades if duty cycle later requires added thermal headroom.

How does the M2 EnDat 2.1 multiturn system in MSK100B-0200-NN-M2-BP2-RNNN enhance indexing or synchronized motion?

It provides absolute position over 4,096 revolutions with 2048 signal periods for enabling fast homing-free startup and tight phase alignment. Its deterministic digital link simplifies diagnostics and supports high loop gains with low interpolation error.

Why specify the electrically released 70 Nm holding brake on MSK100B-0200-NN-M2-BP2-RNNN?

The spring-applied brake prevents axis drift on vertical loads or during E-stop for reducing risk while powered down. Its electrical release (24 V DC) integrates easily with safety relays and allows controlled stop/hold sequencing.

How do increased concentricity and a keyed shaft on MSK100B-0200-NN-M2-BP2-RNNN influence coupling precision and bearing life?

The tighter run-out (per DIN 42955 references for MSK) minimizes radial vibration for improving servo bandwidth and surface finish on machine tools. Its keyway provides positive torque transmission and repeatable phasing for gearboxes or timing pulleys.

What does the “BP2” B-side power connector mean for cable routing and EMC on MSK100B-0200-NN-M2-BP2-RNNN?

The B-side placement helps separate motor-power from feedback runs and can shorten conduits in certain layouts. Its connectors are rotatable (A/B, L/R) for aiding strain-relief and minimizing loop area for conducted/radiated emissions.
