Following frequency converter parameters helps you control and adjust the operation and performance of electric motors by varying the supplied frequency and voltage. Incorrectly set parameters can lead to equipment damage, performance issues, costly downtime, and repairs. This guide provides practical advice on setting up key parameters for frequency converters, ensuring you get the most out of your equipment.
Minimum and Maximum Operating Frequency
The minimum and maximum operating frequencies define the range of speed within which your frequency converter operates. Setting these limits prevents damage to both the converter and the connected machinery. Consider your system’s operational requirements, and make sure these limits align with your equipment specifications.
Frequency Limitations
Frequency limitations control the converter’s output range. You can also use them to control the speed of the connected machinery, such as conveyor belts and fans. Always configure frequency limitations to the unique application when your converter is in use.
Acceleration and Deceleration Time
Acceleration and deceleration time control how quickly a motor reaches operating frequency and slows down from operating frequency to zero. Set the acceleration current lower than the converter’s overcurrent capacity to prevent overvoltage. Another good rule of thumb is to troubleshoot these parameters by starting with longer times and progressively shortening them until there are no warning alarms.
Torque Boosting
Torque boosting, also known as torque compensation, provides extra torque when a motor operates at a low speed. This supports the operation of the motor during acceleration. You can set the parameter to an automatic or manual mode, which affects the acceleration curve and energy efficiency depending on the load characteristics.
Electronic Thermal Overload Protection
Electronic thermal overload protection safeguards your frequency converter and connected equipment from overheating. This parameter calculates the CPU’s temperature based on operating current and frequency and shuts down the system if it exceeds safe levels. Enable this protection mechanism and set it to match the thermal capacity of your equipment.
Setting up frequency converter parameters involves considering various factors for efficient and reliable operation. Following these guidelines can optimize performance and extend the life of your equipment.
