These parameters determine the speed and torque of the motor, so it is important to set them correctly. The voltage setting should match the voltage of the power supply, while the frequency setting should match the frequency of the power supply. Voltage and Frequency: The voltage and frequency parameters are the most basic and important settings that need to be configured in a VFD.Ensure the VFD is set to Factory Defaults as the starting point ( P053=2 FACTORY RESET).Now, its time to set up the Powerflex 525 Parameters: It is usually located on the outside of the motor housing and looks something like this: Lets assume the line voltage feeding the VFD is 460VAC, 3Ph, 60Hz. In this article, we will outline the basic parameters that need to be set up in a VFD for optimal performance.įirst, locate the motor nameplate. Setting up Powerflex 525 parameters correctly is crucial to ensure that the motor runs smoothly and efficiently. (2) Setting is specific to PowerFlex 525 drives only.Variable Frequency Drives (VFDs) are electronic devices that control the speed of an AC motor by adjusting the frequency of the electrical power supplied to the motor. (1) Select this setting if using the optional PowerFlex 25-COMM-E2P, 25-COMM-D, or 25-COMM-P adapters as the speed reference. P047 is the factory default speed reference unless overridden. Changes to these inputs take effect as soon as they are entered. Selects the source of speed command for the drive. (2) Setting is specific to PowerFlex 525 drives only.įor all settings except when t064 is set to 1 “Level Sense”, the drive must receive a leading edge from the start input for the drive to start after a stop input, loss of power, or fault condition. (1) Select this setting if using the optional PowerFlex 25-COMM-E2P, 25-COMM-D, or 25-COMM-P adapters as the start source. Start and Speed Reference Control on page 46 P046 is the factory default start source unless overridden.
