How does the 70 Nm electrically released holding brake impact system design?

The brake allows torque retention when de-energized, which is helpful for vertical axes or safety holds, but the control supply must power it appropriately at shutdown or during fault. Electrically releasing it means that in a power loss, the brake will engage, so you must plan for safe fallback.

How does continuous torque of 57 Nm compare to peak torque of 160 Nm in motion planning?

You can use the 160 Nm during short bursts for acceleration or transient loads, but continuous duty must stay near 57 Nm to avoid overheating — motion profiles must be dimensioned for thermal capacity. Exceeding continuous torque for too long reduces lifetime or risks thermal overload.

What installation constraints stem from the right-side power connector?

Cable routing must allow clearance and stress relief on the right side of the motor; tight cabinets or adjacent modules may block the connector. Also, any connector alignment or bending radius must be respected, especially for high-current lines.

How do you size the drive supply given a 137.7 A maximum current rating?

The drive must supply that peak without voltage collapse or overheating, so select DC bus, smoothing caps, and wiring to handle transients. Keep cable impedance low to avoid voltage drop under high current peaks.

How critical is the “requires Cooling FN” constraint in system integration?

It implies that under some modes or specs, forced cooling (fan or blower) must be used — you cannot rely solely on natural cooling in all duty cases. Ignoring that can push the motor into thermal overload in high duty or high ambient.
