LAPOND AC 220V/18KW 25HP Variable Frequency Drive Instruction Manual

1. Ifihan

This manual provides instructions for the safe and efficient operation of the LAPOND AC 220V/18KW 25HP Variable Frequency Drive (VFD). This VFD is designed to convert single-phase or three-phase 220VAC input to three-phase 220VAC output, suitable for controlling three-phase asynchronous motors up to 20HP (15kW) 55Amps.

The LAPOND VFD features high stability, low failure rate IGBT modules, and a robust cooling system. It includes a detachable operation panel for remote control and enhanced digital/analog terminals, supporting Mach3 function and RS-485 communication.

Read all safety warnings and instructions carefully before installation, operation, or maintenance of the VFD. Failure to follow these instructions may result in electric shock, fire, serious injury, or death.

• This VFD is ONLY applicable to three-phase asynchronous motors.
• Ensure proper grounding of the VFD and the motor to prevent electric shock.
• Disconnect all power sources before performing any wiring, inspection, or maintenance. Wait for the VFD's indicator lights to turn off completely before touching any components.
• If your motor operates under heavy load, select a VFD with higher horsepower than your motor's rated capacity.
• For air compressors, which have a very large instantaneous starting current, select a VFD with at least twice the horsepower of the motor to avoid overcurrent. For example, for a 2 HP compressor, a 4 HP or 5 HP VFD is recommended.
• Do not start the motor directly after the VFD is powered on. The VFD's soft-start capability prevents high current to the power grid and mechanical shock to the machine system.
• Install the VFD in a clean, dry, well-ventilated area, free from direct sunlight, corrosive gases, conductive dust, and excessive vibration.

• Input Power (R, S, T): Connect single-phase or three-phase AC 220V power supply to these terminals.
• Ìjáde Mọ́tò (U, V, W): Connect the three-phase asynchronous motor to these terminals.
• Grounding (⚧): Connect the VFD to a reliable ground. This is critical for safety.
• Braking Resistor (P+, PB): If an external braking resistor is required for applications needing rapid deceleration, connect it to these terminals.

  • Ensure the RUN command is active (e.g., RUN key pressed, or external control signal).
  • Check motor wiring for correct phase sequence and connections.
  • Verify that no protection (e.g., overload, overcurrent) is active. Reset if necessary.
• Overcurrent/Overload Protection (Error Code):
  • Check the motor load. Reduce the load if it exceeds the motor's capacity.
  • Ensure the VFD's capacity is appropriate for the motor, especially for high-starting current applications like compressors (refer to Safety Information).
  • Inspect motor and VFD for any short circuits.
• Apọjutage/ Undervoltage (Error Code):
  • Check the stability and voltage level of the input power supply.
  • Fun overvoltage during deceleration, consider installing a braking resistor if not already present.
• Overheating (Error Code):
  • Ensure proper ventilation around the VFD.
  • Clean the cooling fan and heat sinks to remove dust and obstructions.
  • Verify ambient temperature is within specifications.
