Frequently Asked Questions
What does the optical multiturn absolute Hiperface encoder (128 signal periods) contribute on this model?
The encoder provides absolute position across multiple revolutions with fine interpolation from 128 signal periods for enabling repeatable homing-free startup and accurate velocity feedback. It improves contouring, registration and recovery after power loss.
How does the 7,800 mH winding inductivity influence drive tuning and current ripple?
The higher inductivity smooths current transitions for lowering ripple and easing current-loop tuning for quieter torque production. It may slightly limit electrical bandwidth, so set current-loop gains appropriately and rely on velocity loop to meet dynamic targets.
Why specify a left-side power connector on MSK100A-0450-NN-M1-LP0-NNNN in compact machines?
The side orientation simplifies cable routing in narrow cabinets and multi-axis racks for reducing bend stress at the motor exit. It also helps segregate power from encoder leads to minimize EMI in high-gain loops.
Is MSK100A-0450-NN-M1-LP0-NNNN compatible with Bosch Rexroth IndraDrive platforms?
Yes, the MSK (IndraDyn S) motors are intended for IndraDrive for leveraging native encoder interfaces and motion libraries for multi-axis coordination. It eases commissioning, diagnostics and safety integration on packaging and converting lines.
What advantage does a shaft with keyway offer versus a plain/serrated shaft?
The keyed shaft provides positive mechanical indexing and transmits torque without relying solely on friction for easing hub alignment. It’s well-suited to belt-pulley or rigid-coupling interfaces where repeatable phasing matters.
