Frequently Asked Questions

What advantages does the Hiperface optical, multiturn absolute encoder bring to MSK101C-0450-FN-M1-BG2-NNNN in closed-loop motion?

Its sine/cosine plus RS-485 absolute channel provides fine interpolation (128 periods) and absolute multi-revolution tracking for simplifying homing and improving low-speed smoothness. It enhances position fidelity under dynamic load changes and supports precise synchronization.

How is the 70 Nm electrically released holding brake of MSK101C-0450-FN-M1-BG2-NNNN typically used?

It secures vertical axes or suspended loads during power-off for enabling safe static holding and controlled restart. Its electrical release integrates with drive interlocks to prevent unintended motion during maintenance or emergency stops.

What continuous and peak capability should designers assume at 100 K for MSK101C-0450-FN-M1-BG2-NNNN, and how does that map to motion profiles?

Its 36.5 Nm at 28.6 A continuous and up to 110 Nm at 113 A for short bursts. It is used to shape acceleration, dwell and braking intervals while staying within thermal and RMS current limits.

Why is a plain shaft advantageous for MSK101C-0450-FN-M1-BG2-NNNN in precision couplings?

It supports backlash-free clamping or shrink-fit couplers for minimizing runout and torsional compliance. It helps preserve encoder-referenced accuracy when reversing under cyclic loads or executing contouring profiles.

How does the B-side power connector on MSK101C-0450-FN-M1-BG2-NNNN influence cabinet and cable routing?

It allows motor leads to exit away from load-side tooling for reducing bending stress and EMI coupling into feedback lines. It eases hygienic or confined layouts by separating power and encoder harness paths.
