The JOG function in frequency inverters is a feature that allows the motor to operate at a low, manually controlled speed, usually through a specific button or an external command. This function is useful in various situations, especially in industrial and maintenance processes. Operation only occurs as long as the command is activated, normally through an instantaneous actuation key, so the inverter stops immediately when the command is not pressed by the operator.

What is it:

The JOG function allows the motor to operate at a very low speed, usually for fine adjustments or positioning. The JOG function is activated through a specific button or command on the inverter panel or through an external control device, such as a JOG button on the control box.

What is it for:

1. Adjustment and Positioning: It is very useful for precise positioning of equipment, such as conveyor belts, axles, or other mechanical systems, where it is necessary to move the motor at a low, controlled speed.

2. Maintenance and Inspection: Facilitates engine movement during maintenance or inspection operations, allowing technicians to adjust the position of the equipment without having to operate at its normal operating speed.

3. Fine Adjustments: Allows fine adjustments to be made to the system without the need to change the general speed setting of the inverter, providing more detailed control.

4. Temporary Operation: The JOG function is generally designed for temporary rather than continuous operation. Therefore, it is ideal for applications where the motor needs to be manually moved intermittently.

5. Safety and Precision: In processes where precision is crucial, the JOG function provides a safe and controlled method for moving the motor and equipment, minimizing the risk of errors.

In summary, the JOG function in frequency inverters provides precise manual control over the motor, facilitating adjustment, maintenance and safe operation in situations where precise and controlled movements are required.
