پاور ان پٽ (آر، ايس، ٽي):
Connect the main power supply to these terminals. For the 1PH220VAC model, connect the single-phase input to R and S, leaving T unused or bridged as per specific model instructions. Ensure proper grounding.
موٽر آئوٽ پُٽ (U، V، W):
Connect the motor's three-phase windings to these terminals. Ensure correct phase sequence for desired motor rotation.
ڪنٽرول ٽرمينل:
These terminals are for external control signals such as start/stop commands, speed reference (e.g., 0-10V, 4-20mA), and fault indicators. Refer to the detailed wiring diagram for specific terminal functions.
