Frequently Asked Questions
How does the M1 optical multiturn Hiperface encoder with 128 signal periods on MSK100A-0450-NN-M1-BG1-NNNN affect absolute accuracy and repeatability in micro-positioning tasks?
It provides absolute angle and turn count, avoiding homing and cycle-to-cycle drift. Its 128 periods and drive interpolation achieves fine quantization and stable repeatability for tight movements.
Why is the plain-shaft option on MSK100A-0450-NN-M1-BG1-NNNN preferred for precise gearbox coupling and backlash control?
The cylindrical shaft supports shrink-disc or clamp-hub couplings with concentric fit and minimal micro-play. It improves torsional stiffness and repeatability on reversing axes and precision linear stages.
How do the 13.6 A standstill current and 17.0 Nm continuous standstill torque translate to holding capability and thermal margins in static load cases?
The 100 K standstill point defines sustainable electromagnetic holding without overshoot. Its correct current limiting preserves insulation life while leaving headroom for short transients.
What functional role does the 32 Nm electrically-released holding brake play during emergency stop or power-loss events?
The MSK100A-0450-NN-M1-BG1-NNNN has spring-applied brake that engages automatically when power drops, locking the axis. Its 32 Nm secures vertical or inclined loads until controlled recovery.
How does the listed winding inductivity of 7,800 mH influence current ripple and torque smoothness under PWM drive control?
The MSK100A-0450-NN-M1-BG1-NNNN's higher phase inductance filters switching ripple for smoother torque at a given carrier frequency. It constrains current-loop bandwidth, so tuning must balance responsiveness and noise rejection.
