Installation Guidelines
Mounting: Mount vertically on a flat, non‑flammable surface. Ensure free airflow above and below the drive for convection cooling. Maintain minimum clearances of 50 mm above and below, 10 mm on sides.
Wiring: Use shielded cables for motor, feedback, and communication. Follow recommended wire gauges and terminal torques (typically 0.5‑0.6 Nm for signal terminals, 1.2‑1.5 Nm for power).
Grounding: Connect the drive chassis directly to the system ground using a low‑impedance path. Use a single‑point ground to avoid ground loops.
EMC Compliance: Install the drive in a grounded metal cabinet. Use ferrite cores on signal cables if necessary, and separate power and signal wiring.
