How does the continuous torque at standstill (57 Nm) affect acceleration planning in CNC axes?

That continuous torque defines how much load (inertia or friction) the axis can hold without moving, and it limits available acceleration at zero speed. In motion planning you should ensure the torque demand never exceeds 57 Nm for prolonged periods.

What happens to thermal performance when the motor is used under intermittent duty rather than steady duty?

Under pulsed or S3 duty, the motor will soak higher thermal stress; repeated cycling reduces permissible torque peaks due to heating time constants. Always refer to Rexroth’s duty cycle curves to derate the 160 Nm peak accordingly.

What are the implications of the motor’s winding inductance (~3,200 mH) on the drive current dynamics?

High inductance slows the current rise time in response to voltage commands, thereby limiting how fast the drive can push torque changes. So for very fast transients, ensure your amplifier can supply the required voltage headroom.

How should a B2B system designer size the drive current capacity for safe operation?

The drive should comfortably handle both the continuous current at standstill (34.9 A) and transient demands up to 137.7 A, with margin for peaks. Choose a servo amplifier with ability to supply those peaks (with back-EMF headroom) without saturation.

What is the bearing life expectation under normal operating loads and how is it calculated?

When operated within permissible axial/radial loads and ambient temperature limits, the L₁₀ bearing life is specified at ~30,000 hours per Bosch’s project planning manual.
