Frequently Asked Questions
What positioning benefits does the optical multiturn EnDat 2.1 encoder provide on MSK101C-0300-NN-M2-BP2-RNNN?
The encoder supplies absolute multi-revolution feedback with 2048 signal periods for ensuring precise homing-free startup and high repeatability. Its EnDat also supports rich diagnostics and parameter data exchange for reliable integration with modern drives.
How does natural-convection cooling (FN) influence continuous and peak torque behavior?
The motor safely dissipates heat to sustain 36.5 Nm continuous torque at standstill and reach 110 Nm peak without forced air or liquid circuits. Its thermal limits and mounting conditions still govern duty cycles and permissible load profiles.
Why is a 70 Nm electrically released holding brake useful on MSK101C-0300-NN-M2-BP2-RNNN?
It holds axes against gravity or external disturbance when power is removed for improving machine safety and start-position stability. Its electrical release simplifies controlled engagement/disengagement during servo enable and emergency-stop sequences in vertical or indexer applications.
How does the shaft-with-keyway interface aid torque transmission on MSK101C-0300-NN-M2-BP2-RNNN?
The keyed shaft provides positive mechanical indexing and slip-free torque transfer to pulleys, couplings or gearboxes. It simplifies timing alignment for multi-axis machines while maintaining serviceable assembly and repeatable repositioning.
What’s the role of winding inductivity (≈6,000 mH) in control performance of MSK101C-0300-NN-M2-BP2-RNNN?
The higher phase inductance filters current ripple and eases current-loop tuning with PWM inverters. It also influences dynamic response, while controller bandwidth and voltage headroom must be matched to achieve commanded torque rise times.
