Frequently Asked Questions

What is the practical impact of the 6,000 mH winding inductivity in MSK101C-0300-NN-M1-AG0-NNNN drives?

Its high inductivity lowers current ripple and smooths torque production with PWM inverters for aiding surface finish and contour accuracy. It also eases EMI filtering and benefits current-loop stability at typical IndraDrive switching frequencies.

How does the multiturn absolute Hiperface encoder on MSK101C-0300-NN-M1-AG0-NNNN improve axis recovery and referencing?

The Hiperface optical multiturn system preserves true shaft position over power cycles to eliminate homing on restart and reducing cycle loss. Its 128 signal periods enable precise interpolation for fine positioning and smooth velocity control.

Why use natural-convection cooling on product code MSK101C-0300-NN-M1-AG0-NNNN instead of forced ventilation?

The natural convection removes heat without fans or blowers for reducing maintenance points and contamination ingress in food, packaging or clean-adjacent environments. Its thermal constants are predictable for simplifying continuous-torque sizing at 100 K temperature rise.

How do the continuous 36.5 Nm @100 K and 110 Nm peak torque values influence servo sizing for machine tools?

They allow generous acceleration reserves for spindle indexing, rotary tables or heavy axes while sustaining feed torques under thermal limits. Its balance supports short move profiles without exceeding drive current or thermal envelopes.

What are the integration benefits of the A-side power connector used on MSK101C-0300-NN-M1-AG0-NNNN?

Its A-side routing simplifies cable management in tight enclosures and reduces bend-radius stress at the motor face. It also standardizes pin-outs with Rexroth cable sets for quick IndraDrive commissioning and service.
