About PowerFlex 4
The PowerFlex 4 series is a series of adjustable frequency drives that are fully designed by Allen-Bradley/Rockwell Automation. This kind of equipment is used to control induction motors by modifying their frequency and voltage. The variables that can be controlled are the motor speed, torque, start, and stop. A variable-speed motor cannot operate on its own without any kind of control. When the motor is attached to an adjustable frequency drive, each change or variation is programmed and thus performed smoothly so that they will not cause any damage to the motor. These drives provide secure and safe operations.
The Allen-Bradley/Rockwell Automation PowerFlex 4 series adjustable frequency drives come with different voltages, and 2 of them are intended for 3-phase operations and the other 2 are intended for single-phase operations. Their Horsepower ratings will depend fully on the current that is used at a specific voltage. There are other things to consider when choosing 1 of these drives such as the enclosure and the mounting mechanisms. The Allen-Bradley/Rockwell Automation PowerFlex 4 series adjustable frequency drives feature a fixed keypad and although these include filters, the drives will still need to be grounded. Besides grounding the drive, it is recommended to use shielded cables and to separate the power cables from the signal cables. Another important recommendation is to install the drives as near as possible to the motors in order to avoid power loss phenomena. Drives from this series need to have proper ventilation when operating. The ambient air temperature should not surpass 40 degrees Celsius if the drives are enclosed, and it should not surpass 50 degrees Celsius when they are used with open enclosures.
