Temperature Range

Different kinds of the PowerFlex Architecture-7 series drives have varying operating temperature ranges, which reflects how well they function in various industrial settings. The maximum ambient temperature (without derating) for open IP 20-rated PowerFlex 700 drives is between 0 and 50 degrees Celsius. All enclosure choices for the PowerFlex 753 have a storage temperature range of -40 to 70 degrees Celsius. To accommodate settings where greater ambient temperatures may be encountered, the PowerFlex 70 is made to operate within a somewhat more constrained temperature range of 32 to 104 degrees Fahrenheit. With a wider operating temperature range of 0°C to 50°C, the PowerFlex 750 and PowerFlex 755 series drives offer versatility for usage in more harsh settings, such as those with higher ambient temperatures or frequent temperature swings.

Control Topologies

Different control topologies are available for the PowerFlex 7 series drives to meet a range of industrial automation requirements. PowerFlex 700 drives provide a vector control technique that incorporates Allen-Bradley Force Technology for sophisticated motor control. These drives also provide versatile and accurate control for both conventional and demanding applications by supporting sensorless vector control and voltage per hertz. PowerFlex 700S drives provide a variety of motor control methods, including flux vector control. Slip compensation, safe torque-off, droop control, inertia ride-through, PI control, and user control sets are among the features that the PowerFlex 70 employs. The drives of the PowerFlex 753 series enable voltage per hertz control, sensorless vector control, and vector control with FORCE technology. Furthermore, the PowerFlex 755 AC drives allow a variety of control schemes. Vector control with FORCE technology, voltage per hertz control, permanent magnet motor control, and sensorless vector control are among the possible control alternatives. The PowerFlex 755TS drives use a number of application-specific factors in addition to TotalFORCE control technology. Ultimately, the PowerFlex 700H drives support Volts-per-Hertz control and sensorless vector control modes.

Communication Protocols

Allen-Bradley provides optional communications adapters for the USB, Ethernet, ControlNet, and DeviceNet networks, among other communication possibilities, for the PowerFlex 700 series. Ethernet and ControlNet networks are among the sophisticated communication features offered by the PowerFlex 700S series. In order to improve performance in big systems, it also supports high-speed fiber-optic connections (SynchLink) for data transfer and synchronization between drives. The PowerFlex 753’s dual-port Ethernet module allows customers to benefit from robust, fast Ethernet networks fully. The PowerFlex 755 has strong connectivity features, such as DeviceNet and Ethernet/IP. Because it offers pre-engineered power option bays, integrating it with different industrial networks is simple. Like the PowerFlex 755, the PowerFlex 755TS variant is extremely compatible with Allen-Bradley systems since it supports Ethernet/IP connectivity. Additionally, it provides versatility in regulating torque, velocity, and motor position.
