Frequently Asked Questions

How does the M2 optical multiturn EnDat 2.1 encoder in the MSK100B-0200-NN-M2-AG2-RNNN improve positioning and commissioning?

It preserves absolute position over 4096 mechanical revolutions and communicates digitally for enabling precise homing-free startups. Its encoder built-in data memory lets IndraDrive read motor parameters automatically for simplifying setup and avoiding mismatched drive tuning.

Why is natural-convection cooling appropriate on MSK100B-0200-NN-M2-AG2-RNNN, and when would another cooling method be selected?

The natural-convection (self-cooling) minimizes components and suits moderate thermal loads or tightly integrated machine frames. It also supports alternative cooling options when higher continuous torque density or elevated duty cycles require more heat rejection.

How is the 70 Nm electrically released holding brake used on vertical or safety-critical axes of MSK100B-0200-NN-M2-AG2-RNNN?

It is intended to hold a de-energized axis at standstill rather than stop dynamic motion for preventing sag on Z-axes or suspended loads. Its specifies use at standstill and lists the 70 Nm option in the MSK brake data.

What does “increased concentricity” on the plain shaft achieve in MSK100B-0200-NN-M2-AG2-RNNN?

The shaft concentricity reduces radial runout at the coupling for improving velocity ripple and contouring accuracy. It also eases alignment for backlash-sensitive couplings for lowering bearing loads and improving long-term geometric stability.

How does EnDat 2.1 compare with Hiperface or single-turn variants in the MSK family?

The EnDat 2.1 is a digital, bidirectional interface offering absolute data and diagnostics, it supports both single- and multiturn optical options, including M2 for multiturn.
