1. Introducció
This manual provides detailed instructions for the installation, operation, and maintenance of the MOLLOM 0.75KW 1HP G70 Variable Frequency Drive (VFD). This VFD is designed to control the speed of three-phase AC motors, offering precise control for applications such as CNC routers, milling machines, drilling machines, and various other industrial equipment. It supports both single-phase and three-phase 220V input and provides a three-phase 220V output with a frequency range of 0-3000 Hz.
Key features include a user-friendly keyboard design, digital display, RS485 communication port, and strong anti-jamming capability. Please read this manual thoroughly before installation and operation to ensure safe and efficient use of the device.
2. Instruccions de seguretat
Seguretat elèctrica:
- Ensure all power is disconnected before performing any wiring or maintenance.
- Només personal qualificat ha d'instal·lar i mantenir aquest equip.
- La connexió a terra adequada és essencial per evitar descàrregues elèctriques.
- The frequency converter must be directly connected to the motor. Control of motor start and stop must be managed by the frequency converter to prevent damage.
Condicions ambientals:
- Avoid installation in environments with excessive humidity, water mist, water droplets, or where metal objects could fall into the unit, as this may cause short circuits.
- Ensure adequate ventilation around the VFD for proper heat dissipation.
Nota important: This VFD does not support external resistors. For heavy load motors, consider a higher power level VFD or consult technical support for model selection.

4. Instal·lació
4.1. Muntatge
Mount the VFD in a vertical position on a flat, stable surface. Ensure sufficient clearance around the unit for proper airflow and heat dissipation. Avoid mounting in direct sunlight or near heat sources.
4.2. Instruccions de cablejat
Refer to the wiring diagram and the video for correct connections. Ensure all connections are secure and properly insulated.
- Potència d'entrada (R, S, T): For single-phase 220V input, connect to any two of the R, S, T terminals. For three-phase 220V input, connect to R, S, T terminals.
- Sortida del motor (U, V, W): Connect the three-phase motor wires to the U, V, W terminals.
- Posada a terra: Connect the ground wire to the designated grounding terminal.
- Terminals de control: The VFD supports various control terminals for external switches, potentiometers, and RS485 communication. Refer to the detailed terminal block for specific connections.
4.3. Comunicació RS485
For RS485 communication, connect RS485+ and RS485- to the corresponding terminals. If the control device requires a power supply, connect GND and 24V terminals.
