Frequently Asked Questions

What feedback topology does MSK100A-0300-NN-S1-AG0-NNNN use, and how does it influence servo loop tuning?

It employs an optical Hiperface singleturn encoder with 128 signal periods for enabling accurate commutation and velocity estimation for stable, high-bandwidth current/velocity loops. Its deterministic interface simplifies drive-side interpolation and minimizes quantization error during low-speed contouring.

How does the motor’s natural-convection cooling affect continuous torque for MSK100A-0300-NN-S1-AG0-NNNN?

The convection cooling makes the motor delivers 17.0 Nm continuous torque at standstill (100 K) and 11.6 A continuous current, while thermal margins depend on installation airflow and mounting mass. For higher duty cycles, Rexroth supports retrofit blower or liquid-cooling options on MSK series variants.

What does the IP65 classification mean for MSK100A-0300-NN-S1-AG0-NNNN in production environments?

The IP65 protects against dust ingress and low-pressure water jets for supporting deployment near coolants, washdown spray, or paper/film dust. Its cable glands and correct connector orientation (A-side power) are critical to maintain enclosure integrity at speed.

How does the motor’s inertia (≈0.011 kg·m²) influence axis design with MSK100A-0300-NN-S1-AG0-NNNN?

The moderate rotor inertia improves disturbance rejection on belt/ball-screw drives and allows crisp accel/decel without excessive jerk. Its servo tuning should consider load-to-motor inertia ratio to avoid resonance in compliant couplings and long carriages.

What connector orientation and shaft interface are provided on MSK100A-0300-NN-S1-AG0-NNNN, and why might that matter?

the A-side power connector simplifies cable routing in left-hand machine bays and the plain shaft supports precision couplings or pulleys without keyseat imbalance. Its physical interfaces aid compact panel layouts and low-runout transmission.
