When sourcing a Monarch inverter (such as the NICE 3000+ or NICE 1000+ series), you must verify the rated power (kW) and rated current (A) to ensure they match your elevator motor's capacity. It is critical to confirm the input voltage range (typically 3-phase 380V-460V) and the control mode, such as Closed-loop Vector Control, which is essential for the smooth start and stop transitions required in passenger elevators. Additionally, check for encoder interface compatibility (e.g., SIN/COS, UVW, or ABZ) to ensure seamless feedback integration.
