Frequently Asked Questions

What does natural-convection cooling mean for duty cycle and thermal behavior on MSK076C-0300-NN-S1-UG0-NNNN in S1 continuous operation?

The heat is dissipated through the frame, so airflow around the motor largely defines permissible continuous torque. Its 25-minute thermal time constant smooths temperature excursions in intermittent moves but sustained overload still requires derating or supplemental machine-side cooling.

How do the 43.5 Nm maximum torque and 32.4 A peak current of MSK076C-0300-NN-S1-UG0-NNNN translate into usable overload capability?

They define short-term acceleration torque beyond continuous limits for enabling faster indexing and recovery from process disturbances. Its drive parameterization should enforce time-at-peak constraints to protect windings and maintain magnet and bearing lifetimes.

Why are 240° rotatable encoder and power connectors advantageous on the MSK076C-0300-NN-S1-UG0-NNNN during integration?

They allow optimal cable egress and strain-relief in cramped enclosures for reducing bend stress and EMI coupling. Its orientation flexibility also shortens installation time and prevents connector clashes with adjacent axes or guarding.

Is MSK076C-0300-NN-S1-UG0-NNNN interoperable with Rexroth IndraDrive controllers and third-party systems using Hiperface?

Yes, the Rexroth specifies IndraDrive compatibility for MSK series and Hiperface is widely supported for analog Sin/Cos with a digital parameter channel. The cable sets, scaling constants and encoder ID in the drive firmware is of importance to verify.

What ingress protection level is typical for MSK IndraDyn S motors used in shop-floor environments, and what should be verified for this code?

The MSK series commonly ship with IP65-class sealing for dust and low-pressure water jets in standard configurations.
