Frequently Asked Questions
The 4GN-120K is designed for universal compatibility with both AC and DC motors. It features standardized mounting interfaces that accommodate NEMA and IEC motor frames, making integration straightforward with most industrial motor types.
The 120:1 reduction ratio significantly increases output torque while proportionally decreasing output speed. For example, with an input speed of 1800 RPM, the output speed would be approximately 15 RPM, while the output torque would be approximately 120 times the input torque (minus efficiency losses).
The gear reducer is factory pre-lubricated and typically requires minimal maintenance. Recommended maintenance includes periodic lubrication condition checks (every 6-12 months depending on operating conditions), inspection of seals and mounting hardware, and monitoring for unusual noise or vibration.
Yes, with its IP54 protection rating, the 4GN-120K is suitable for industrial environments with dust and water splash exposure. For more severe conditions, additional protective measures or higher IP-rated enclosures may be required.
Integration involves selecting an appropriate motor compatible with your PLC's control capabilities, proper wiring of motor control circuits, and programming the PLC to manage speed, direction, and position control. Detailed integration guides are available from Koeed Industrial Automation.
