Frequently Asked Questions

What control advantages arise from the optical multiturn absolute Hiperface encoder (128 periods) on this IndraDyn S motor?

It retains multi-revolution position after power loss for eliminating homing on startup and protecting tooling. Its Hiperface interface stores motor data and supports accurate commutation and fine interpolation for stable, high-gain loops.

How does the 7,600 mH winding inductivity of MSK100B-0200-NN-M1-LP0-NNNN affect current ripple, torque ripple, and achievable servo bandwidth?

The higher inductivity smooths current transitions and reduces ripple for aiding EMC and current-loop stability. Its tradeoff is slightly reduced high-frequency response to managed via current-/velocity-loop tuning and sufficient DC-bus voltage headroom.

What integration considerations follow from the left-side power connector orientation on MSK100B-0200-NN-M1-LP0-NNNN?

The left exit can simplify routing along machine uprights and avoid crossovers between axes. It maintains separation between power and encoder harnesses.

Why specify a keyed shaft for this unit instead of a plain or taper fit?

The keyed couplings provide positive torque transmission and deterministic angular alignment without relying solely on friction. Tit implements DIN-6885 keyways with sealing-ring options to ease repeatable assembly and service under dynamic loads.

What are the motion-accuracy and uptime benefits of the encoder’s multiturn absolute capability for MSK100B-0200-NN-M1-LP0-NNNN?

The absolute position is preserved across power cycles for up to 4,096 turns for enabling immediate controlled moves without homing. It shortens recovery and reduces risk when tooling or fixtures can’t tolerate hard stops.
