Frequently Asked Questions

How does the S1 optical single-turn Hiperface encoder (128 signal periods) in MSK100B-0200-NN-S1-BP2-NNNN improve commutation accuracy and response?

The Hiperface sine/cosine signals enable fine interpolation for precise electrical angle estimation for aiding smooth FOC commutation and low ripple torque. Its absolute single-turn data reduces homing moves and speeds recovery after E-stop.

What does the “0200” winding/speed code imply for MSK100B-0200-NN-S1-BP2-NNNN selection and kV/torque-constant tradeoffs?

This winding variant targets a lower base speed with higher torque constant, while reaches ~4100 rpm maximum speed. Its balance favors higher torque per ampere while keeping voltage within common IndraDrive ranges.

How does the electrically released 70 Nm holding brake benefit vertical axes or index stations on MSK100B-0200-NN-S1-BP2-NNNN?

The 24 V-released brake safely holds load when power is off for minimizing drift on Z-axes and securing fixture positions. Its drive energizes to release the brake for preventing drag losses in motion modes.

How do the keyed output shaft (DIN 6885) and B-side power connector aid integration and reliability?

The keyway simplifies torsion-resistant hub coupling and repeatable phasing for lowering backlash risk. Its B-side flange socket routes cabling away from machine tooling to support cleaner harness layouts and easier service access in tight frames.

How does the stated winding inductivity (7,600 mH) affect current-loop tuning and EMC on MSK100B-0200-NN-S1-BP2-NNNN?

The higher phase inductance attenuates PWM ripple for easing EMI filtering and enabling stable current loops at moderate bandwidth. Its controllers may require refined decoupling/feed-forward and slightly lower current-loop gains to preserve phase margin during fast steps.
