A standard motor without extra sealing or environmental protection is more vulnerable to dust, moisture, or debris ingress, so in harsh environments you may need external protection or an upgraded variant to maintain reliability and avoid encoder errors.

By comparing continuous torque (57 Nm) and peak torque, and knowing the motor’s thermal mass, you can derive how long you can run at high torque before the motor overheats (i.e. allowable duty cycle). In practice, manufacturer’s planning manuals (e.g., the Rexroth IndraDyn S Project Planning Manual) give thermal time constant curves for safe peak durations.

Without a holding brake, the motor can’t resist external torques when unpowered, so for vertical axes, safety zones, or applications needing fail-safe hold, you’ll need an external brake or mechanical locking device.

You should consider the motor’s maximum current (99.9 A) plus margin, select a DC-link filter that can handle ripple currents above that, and ensure its inductance doesn’t overly degrade the drive’s voltage dynamics; also coordinate the drive manufacturer’s recommended input filter specs (from datasheet) to avoid oscillations.

The left-side power connector means cabling must exit sideways, so you must ensure sufficient cable bend radius clearance and avoid running the cable across moving structures that might obstruct or fatigue the wires.
