Does the lack of a holding brake limit vertical-axis use?

Yes, without a brake, vertical axes need a mechanical counterbalance (e.g., spring/gas) or a fail-safe external brake; drive torque alone is not a safe holding method during E-stop. The MSK manuals cover brake options and connection standards for variants that include brakes.

How do 2048 signal periods translate to practical positioning resolution?

Sin/Cos encoders with 2048 periods are interpolated in the drive, yielding much finer internal counts per rev and smoother velocity loops than the base period count implies. EnDat-based singleturn feedback in MSK motors is intended for high-precision servo control when paired with compatible drives.

What shaft-loading limits should I observe when using keyed couplings or pulleys?

Stay within the specified radial/axial load curves to preserve the 30,000-hour bearing L10 life; oversizing pulleys or belt tension shortens bearing life quickly. The IndraDyn S planning manual provides load curves and lifetime assumptions for all MSK frames.

What’s the realistic top speed and what does that mean for gear ratio choices?

MSK101D variants run up to about 3400 rpm; selecting a ratio that keeps motor speed below this while meeting axis torque avoids field-weakening operation. Published specs for the MSK101D list 3400 rpm with torque peaking to 160 Nm.

For Bosch Rexroth Indramat MSK101D-0200-NN-S2-BP0-RNNN, how should I size for 57 Nm continuous vs. 160 Nm peak?

Use 57 Nm for thermal steady-state duty at the given winding temperature basis and reserve 160 Nm for short transients within the drive’s peak-current time limits; verify cabinet temperature and cooling to avoid overheat trips. Published data for this exact code confirms 57 Nm continuous at standstill and 160 Nm peak.

MSK-101D-0200-NN-S2-BP0-RNNN

The IndraDyn S Synchronous Servomotor MSK101D-0200-NN-S2-BP0-RNNN by Bosch Rexroth uses an optical singleturn encoder with 2048 signal periods and EnDat2.1 interface. It delivers 57.0 Nm continuous torque and up to 160.0 Nm peak torque, with natural convection cooling. Ideal for use in robotics, metal forming, and packaging machinery.
