Frequently Asked Questions

How does natural-convection cooling on MSK100A-0200-NN-M1-LG1-NNNN impact sizing and mounting choices?

The passive cooling relies on the machine structure as a heatsink, so thermal performance depends on mounting surface, airflow and duty cycle. It reduces ancillary hardware compared with forced-air/liquid options available across the MSK family.

What does the Hiperface multiturn optical encoder in MSK100A-0200-NN-M1-LG1-NNNN contribute to axis control?

It provides absolute position information across multiple revolutions and an analog sine/cosine track for fine interpolation for enabling precise homing-free startup and smooth velocity control. Its 128 signal periods are interpolated by the drive for high effective resolution.

Why is a 32 Nm electrically-released holding brake used on this motor? (MSK100A-0200-NN-M1-LG1-NNNN)

The power-off applied electrically released brake secures vertical or safety-critical axes during e-stops or servo disable to prevent back-drive. Its 32 Nm static torque suits mid-inertia loads and complements the motor’s 17 Nm continuous standstill torque for dependable holding.

How does the 13,900 mH winding inductivity in MSK100A-0200-NN-M1-LG1-NNNN influence control dynamics?

Its inductance attenuates current ripple and eases current-loop tuning, which helps smooth torque production at low speed. Its tradeoff is slower di/dt response, so bandwidth and field-weakening limits should be matched to the application load profile.

How do the 10.4 A continuous standstill current and 17.0 Nm torque guide drive and gearbox pairing for MSK100A-0200-NN-M1-LG1-NNNN?

They define thermal limits for continuous holding or low-speed process moves and help size the IndraDrive current rating. Its gear ratios should keep required torque below 17 Nm continuous for reserving 54 Nm peak for transient moves.
