LAPOND K100-022G1 30HP/22KW Variable Frequency Drive User Manual

1. Maklumat Keselamatan Penting

This Variable Frequency Drive (VFD) is designed for controlling three-phase asynchronous motors. Adhere to all safety precautions during installation, operation, and maintenance to prevent injury or equipment damage.

• Keserasian Motor: This VFD is ONLY applicable to three-phase asynchronous motors.
• Horsepower Selection: If your motor operates under heavy load, select a VFD with higher horsepower than your motor's rating.
• Air Compressor Application: For air compressors, due to large instantaneous starting currents, select a VFD with twice the horsepower of the motor. For example, a 2 HP compressor requires a 4 HP or 5 HP VFD.
• Soft-Start Function: The VFD provides a soft-start capability to prevent high current surges to the power grid and mechanical shock to the machine system. Do NOT start the motor directly after the VFD is powered on.
• Ensure proper grounding of the VFD and motor.
• All electrical work should be performed by qualified personnel.

5.2 Power and Motor Wiring Diagram (4KW-15KW Example)

Gambar 5.2: Cthample wiring diagram for VFD models between 4KW and 15KW. This diagram illustrates connections for single or three-phase AC 220V input, 3-phase AC 220V output to the motor, grounding, and an optional braking resistor.

Input Power (R, S, T): Connect the AC 220V single or three-phase power supply to the R, S, T terminals. For single-phase input, connect to R and S (or R and T) as per the detailed manual. Ensure a circuit breaker is installed upstream for protection.

Output to Motor (U, V, W): Connect the three-phase motor to the U, V, W terminals. Ensure correct phase sequence for desired motor rotation.

Pembumian: Connect the grounding terminal (marked with earth symbol) to a reliable earth ground. This is critical for safety.

Braking Resistor (P+, PB): For applications requiring rapid deceleration, connect an external braking resistor between P+ and PB terminals. Refer to the VFD's specifications for appropriate resistor values.

Note: The provided diagram is an example for 4KW-15KW models. For the 22KW/30HP model, ensure to consult the specific wiring instructions in the comprehensive manual for terminal designations and current ratings.
