The electrically released brake supplies 70 Nm holding torque, so you must command it to engage before drive power is removed and accommodate its disconnection delay (milliseconds) to prevent unwanted motion. Also, ensure the brake’s inertia and torque are included in the control model.

You get ≈ 0.18° resolution (360°/2048) per revolution, but absolute accuracy depends on encoder interpolation, system latency, and mechanical play—so real-world repeatability is typically tighter than raw counts.

The motor datasheet mandates coolant pH 6–8, maximum inlet pressure ~3.0 bar, and dew point margin (coolant temperature must be ~5 °C below ambient to avoid condensation)

The plain shaft requires a suitable coupling (e.g. flexible, jaw, or bellows type) and precise alignment to minimize runout or bearing loads; misalignment adds parasitic torque and reduces system stiffness. Also consider thermal expansion compensation.

The drive must deliver high peak current during acceleration without voltage collapse or converter DC bus drops; choose a servo amplifier and power supply that can reliably deliver 137.7 A pulses plus margin for voltage drop and cabling losses.
