What operational risk arises from the motor’s 3,200 mH inductance during fast torque transients?

The large inductance slows current rise during acceleration, limiting how fast torque can change and requiring the drive to supply a higher voltage to overcome it. You’ll want a drive with sufficient voltage margin and current regulation bandwidth to fully exploit peak torque.

How does the built-in holding brake torque of 120 Nm impact safety during power loss?

In a power-off state it safely holds the load, but during engagement/disengagement it must be sequenced properly to avoid torque transients. Ensure drive logic cuts motor torque before brake release to avoid collision or mechanical shock.

In closed-loop systems, how critical is the 128 signal-periods (Hiperface) resolution for precision tasks?

It supports sub-micron incremental steps, which allows tight position control for high-precision machinery. However, mechanical backlash, coupling compliance, and loop tuning often dominate over raw encoder resolution.

How should I size the cabling given the peak current of 137.7 A?

Use low-resistance, heavily rated conductors and minimize length to limit IR drop and voltage sag; include proper shielding to avoid EMI with encoder lines. A voltage drop >2–3% under peak current can degrade dynamic response or trip drive protection.

What is the implication of the motor’s thermal time constant of ~100 minutes?

The motor temperature reacts slowly to load changes, so short bursts up to max torque are permitted, but sustained high duty cycles must be derated to avoid overheating.
